The other genome contains 6 tRNA genes in novel locations. Most chelicerates with rearranged mitochondrial genes show a genome-wide reversal of the CA nucleotide bias typical for arthropods on their major coding strand, and instead possess a GT bias. Yet despite their extensive rearrangement , these pseudoscorpion mitochondrial genomes possess a CA bias on the major coding strand.
Phylogenetic analyses of all In order to study the clonal relationship and blaKPC gene detection in clinical isolates of Klebsiella pneumoniae resistant to carbapenems, we analyzed 22 clinical isolates of K. Susceptibility to different antimicrobials was determined, and the presence of carbapenemases was detected by modified Hodge method, phenyl boronic acid synergy and combination discs.
High rates of antimicrobial resistance were found, five strains were negative, at least one phenotypic method, and all carried the blaKPC gene. Clonal spread was observed only in the intensive care unit ICU , while in other services, polyclonality was found. We concluded that blaKPC gene is present in K. Rearrangement of a large novel Pseudomonas aeruginosa gene island in strains isolated from a patient developing ventilator-associated pneumonia.
Bacterial gene islands add to the genetic repertoire of opportunistic pathogens. Here, we perform comparative analyses of three Pseudomonas aeruginosa strains isolated sequentially over a 3-week period from a patient with ventilator-associated pneumonia VAP who received clindamycin and piperacillin-tazobactam as part of their treatment regime.
While all three strains appeared to be clonal by standard pulsed-field gel electrophoresis, whole-genome sequencing revealed subtle alterations in the chromosomal organization of the last two strains; specifically, an inversion event within a novel kb gene island PAGI 12 composed of open reading frames [ORFs]. Predicted ORFs in the island included metabolism and virulence genes.
Examination of a separate cohort of 76 patients with VAP for integration at this tRNA lys recombination site demonstrated that patients exhibiting evidence of integration at this site had significantly higher day mortality. These findings provide evidence that P. All Rights Reserved. Singh, G. Examination of a separate cohort of 76 patients with VAP for integration at this tRNAlys recombination site demonstrated that patients exhibiting evidence of integration at this site had significantly higher day mortality.
Hendrickx, Antoni P. Most Enterococcus faecium isolates associated with hospital outbreaks and invasive infections belong to a distinct genetic subpopulation called clonal complex 17 CC It has been postulated that the genetic evolution of CC17 involves the acquisition of various genes involved in antibiotic resistance, metabolic pathways, and virulence.
To gain insight into additional genes that may have favored the rapid emergence of this nosocomial pathogen, we aimed to identify surface-exposed LPXTG cell wall-anchored proteins CWAPs specifically enriched in CC17 E. Expression at the mRNA level was demonstrated, and immunotransmission electron microscopy revealed an association of the five LPXTG surface proteins with the cell wall. Clonal expansion of T-cell receptor beta gene segment in the retrocochlear lesions of EAE mice.
It has been reported that the T cell receptor V beta 8. We have demonstrated retrocochlear hearing loss in EAE mice in previous studies. Administration of a monoclonal antibody specific to the T cell receptor V beta 8 TcrbV8 subfamily prevented both this type of hearing loss and the central nerve disease. In this study, we examined the role of the TcrbV8.
A clonal expression of T cell receptor beta chain gene segment TcrbV8. The TcrbV8. The TcrbJ2. Only TcrbD2, with a length of 4 amino acids, was observed recombining with these TcrbV8. This dominant TcrbV gene segment TcrbV8. These results suggest that a small subset of antigen-specific T cells migrate to, and expand at, the retrocochlear lesions, which leads to hearing loss.
Cytomorphology of non-small cell lung carcinoma with anaplastic lymphoma kinase gene rearrangement. Cytogenetic analysis was performed with fluorescence in situ hybridization. A total of 12 patients were identified, 10 with available material.
Cellular morphology and smear background was evaluated in the study group, as well as control cases lacking ALK rearrangement. A total of 25 specimens from 10 patients were obtained. Biological valves usually are made from animal tissue. Full Text Available Aim. To study the effect of transcatheter aortic valve implantation TAVI, performed by different types of prostheses and various surgical access, on the prognosis of patients with critical aortic stenosis and comorbidities.
Material and methods. Complications including perioperative mortality, total day mortality, as well as post-hospital mortality were registered during aortic valve replacement, immediately after surgery, before the expiry of 30 days. Mean follow-up was 2. Hospital mortality was on average 6. The number of deaths in the post-hospital period was Valve type and the type of access had no effect on post-hospital mortality. Men died more than 2.
Atrioventricular block, pacemaker implantation, and history of chronic obstructive pulmonary disease were the most significant prognostic factors. An important role of minor stroke and renal failure should be noted. Mortality did not depend on the surgical access or valve type.
All parameters characterizing the intervention were significantly associated with mortality, both during and after surgery. The proportion of survivors at the end of the first year of observation using Corvalve system was Two-year survival was TAVI is the method of choice, reasonable alternative approach for surgical valve replacement in patients with high surgical risk, although.
Valve system incorporating single failure protection logic. A valve system incorporating single failure protective logic. The system consists of a valve combination or composite valve which allows actuation or de-actuation of a device such as a hydraulic cylinder or other mechanism, integral with or separate from the valve assembly, by means of three independent input signals combined in a function commonly known as two-out-of-three logic.
Ball check valve. A pressurized nuclear reactor having an instrument assembly sheathed in a metallic tube which is extended vertically upward into the reactor core by traversing a metallic guide tube which is welded to the wall of the vessel is described. Sensors in each instrument assembly are connected to instruments outside the vessel to manifest the conditions within the core.
Each instrument assembly probe is moved into position within a metallic guide channel. The guide channel penetrates the wall of the vessel and forms part of the barrier to the environment within the pressure vessel. Each channel includes a ball check valve which is opened by the instrument assembly probe when the probe passes through the valve. A ball valve element is moved from its seat by the probe to a position lateral of the bore of the channel and is guided to its seat along a sloped path within the valve body when the probe is removed.
Thermostatic Radiator Valve Evaluation. Dentz, J. A large stock of multifamily buildings in the Northeast and Midwest are heated by steam distribution systems. Losses from these systems are typically high and a significant number of apartments are overheated much of the time.
Thermostatically controlled radiator valves TRVs are one potential strategy to combat this problem, but have not been widely accepted by the residential retrofit market. In this project, the ARIES team sought to better understand the current usage of TRVs by key market players in steam and hot water heating and to conduct limited experiments on the effectiveness of new and old TRVs as a means of controlling space temperatures and reducing heating fuel consumption.
Objective: Cardiac surgical mortality has improved during the last decade despite the aging of the population. An integrated US health plan developed a heart valve registry to track outcomes and complications of heart valve operations. This database was used for longitudinal evaluation of mitral valve MV outcomes from to at four affiliated hospitals.
Methods: We identified patients in the Apollo database who underwent initial MV procedures. Internal administrative and Social Security Administration databases were merged to determine survival rates. Electronic health records were searched to ascertain demographics, comorbidities, and postoperative complications. Cox regression was used to evaluate mean survival and identify risk factors.
Results: The procedures included mechanical valve replacements, tissue valve replacements, and annuloplasties. Mean survival was 8. Early in the study, there was a preference for implanting mechanical MVs. Beginning in , more patients received tissue valve replacements rather than mechanical valves.
Over time, there was an increasing trend of annuloplasty. Cox regression analysis identified the following risk factors for increased ten-year mortality: tissue valve implantation; advanced age; female sex; nonelective, nonisolated procedure; diabetes; postoperative use of banked blood products; previous cardiovascular intervention; dialysis; and longer perfusion time.
Hospital location, reoperation, preoperative anticoagulation, and cardiogenic shock were not statistically significant risk factors. Conclusions: When controlling for other risk factors, we observed a lower long-term survival rate for tissue valve replacement compared with. Full Text Available Background: There have been a number of studies on mitral valve replacement and repeated percutaneous mitral balloon valvotomy for mitral valve restenosis after percutaneous mitral balloon valvotomy.
However, studies on mitral valve repair for these patients are rare. In this study, we analyzed postoperative outcomes of mitral valve repair for mitral valve restenosis after percutaneous mitral balloon valvotomy. Methods: In this study, we assessed 15 patients mean age, The mean interval between the initial percutaneous mitral balloon valvotomy and the mitral valve repair was The mean preoperative Wilkins score was 9.
Results: The mean mitral valve area obtained using planimetry increased from 1. The mean pressure half time obtained using Doppler ultrasound decreased from The mean pressure gradient obtained using Doppler ultrasound decreased from 9. There were no early or late deaths.
Thromboembolic events or infective endocarditis did not occur. The 5-year event-free survival was Conclusion: On the basis of these results, we could not conclude that mitral valve repair could be an alternative for patients with mitral valve restenosis after percutaneous balloon mitral valvotomy. However, some patients presented with results similar to those of mitral valve replacement. Further studies including more patients with long-term follow-up are necessary to determine the possibility of this application of mitral valve repair.
Mitral valve replacement is the procedure of choice in patients with severe mitral valve disease. However, these patients are surviving longer and are thus at an increased risk of prosthesis failure or valve -related complications. Study population: All patients undergoing redo mechanical mitral valve replacement surgery between January and December Study design: Retrospective analysis of patients undergoing redo mitral valve replacement. Patients were identified from theatre record books, their files were electronically accessed and pertinent information extracted onto a data capture sheet.
The data was stored on an Excel datasheet. Mean duration between first surgery and redo was 8. Presenting features at redo surgery were congestive cardiac failure 27 , chest pain 11 and palpitations Mean preoperative Ejection Fraction was Thirty-two patients had tricuspid regurgitation.
The most commonly used valve was the On-X. Mean presenting INR was 1. Two patients died postoperatively. Twelve patients Physiologic changes during pregnancy can deteriorate or improve patients' hemodynamic status in the setting of valvular heart disease. There are sparse data regarding the effect of pregnancy on valve hemodynamics in normal pregnant women with known valvular heart disease.
In a prospective study from July to January , a total of 52 normal pregnant women who had mitral stenosis, aortic stenosis, or a history of mitral valve or aortic valve replacements were assessed. All patients underwent echocardiographic examinations and hemodynamic parameters were measured for both the mitral valve and aortic valve at first, second, and third trimesters.
Although most hemodynamic parameters i. The ratio of changes between trimesters for valve area and dimensionless velocity index were comparable. No clinical decompensations were observed except for 3 and 7 cases of deterioration to functional class II at second and third trimesters, respectively.
In conclusion, during a full-term and uncomplicated pregnancy, mitral and aortic valve gradients increase without significant changes in valve area that are more marked between the second and first trimester than between the third and second trimester. Aortic valve insufficiency in the teenager and young adult: the role of prosthetic valve replacement.
The contents of this article were presented in the session "Aortic insufficiency in the teenager" at the congenital parallel symposium of the Society of Thoracic Surgeons STS annual meeting. The accompanying articles detail the approaches of aortic valve repair and the Ross procedure. For many young patients requiring aortic valve surgery, either aortic valve repair or a Ross procedure provides a good option. The advantages include avoidance of anticoagulation and potential for growth. In other patients, a prosthetic valve is an appropriate alternative.
This article discusses the current state of knowledge regarding mechanical and bioprosthetic valve prostheses and their specific advantages relative to valve repair or a Ross procedure. In current practice, young patients requiring aortic valve surgery frequently undergo valve replacement with a prosthetic valve. In the future, the balance among these options may be altered by design improvements in prosthetic valves , alternatives to warfarin, the development of new patch materials for valve repair, and techniques to avoid Ross autograft failure.
Multifunctional four-port directional control valve constructed from logic valves. Their widespread use in many machines and devices causes a continuing interest in the development of their design by both the scientific centers and the industry. The valve design methodology takes into account the need to seek solutions that minimize flow resistance through the valve.
For this purpose, the flow paths are prepared by means of CAD software and pressure-flow curves are determined as a result of CFD analysis. The obtained curves are compared with the curves available in the catalogs of spool type directional control valves. The new solution allows to replace the whole family of spool type four-port directional control valves by one valve built of logic valves.
In addition, the innovative directional control valve provides leak-proof shutting the flow paths off and also it can control flow rate and even pressure of working liquid. A prototype of the valve designed by the presented method has been made and tested on the test bench. The results quoted in the paper confirm that the developed logic type directional control valve is able to meet all designed connection configurations, and the obtained pressure-flow curves show very good conformity with the results of CFD analysis.
The study aim was to assess, in vitro, the hemodynamic modifications produced by transcatheter valves in the Valsalva sinuses, by mean of phase-resolved particle image velocimetry PIV measurements. Flow measurements were performed on a glass mock aortic root that included three polymeric valve leaflets, before and after the implantation of a Medtronic Core Valve device and of an Edwards SAPIEN valve.
All experiments were carried out in a hydro-mechanical cardiovascular pulse duplicator system Vivitro Superpump System SP that reproduced physiologically equivalent pressures and flow rates conforming to the requirements of the standard ISO The flow dynamics, before and after implantation of the two prosthetic devices, was characterized on the basis of phase-resolved velocity field and viscous shear rate measurements. Direct comparison indicated that both transcatheter valves determined a significant variation of flow during the early stages of valve opening and during valve closure.
In general, the presence of the two valve implants significantly reduced the flow activity in the Valsalva sinuses, promoting regions of stagnation at their base. The reduction in flow in the Valsalva sinuses could be associated with the higher incidence of ischemic events reported after transcatheter heart valve implantation.
The incidence of aortic regurgitation AR after transcatheter aortic valve replacement TAVR in a self-expanding and a balloon-expandable system is controversial. Baseline, procedural, and postprocedural inhospital outcomes were compared. A multivariate logistic regression analysis was completed to evaluate for correlates of the primary end point.
The secondary end points included the change in severity of AR at day and 1-year follow-up. There were significant differences in the rates of intraprocedural balloon postdilation with the CV There were no significant differences in inhospital safety outcomes between the 2 groups. In conclusion, the incidence of post-TAVR AR is similar between the CV and the XT valve when performed by experienced operators using optimal intraprocedural strategies, as deemed appropriate, to mitigate the severity of AR.
This study aimed to evaluate the safety and feasibility of transaortic mitral pannus removal TMPR. The median time interval from the previous surgery was 14 years. TMPR was performed in 2 patients through a normal aortic valve. Prophylactic TMPR was performed in 23 patients. There were no early deaths. Concomitant operations included 22 tricuspid valve surgeries 13 replacements, 15 repairs and 32 aortic valve replacements 24 repeats, 8 primary.
To report and compare the results of trabeculectomy with mitomycin C MMC and Ahmed valve implantation in the management of uveitic glaucoma. The records of 41 eyes of 29 patients who underwent trabeculectomy with MMC or Ahmed valve implantation for uveitic glaucoma were retrospectively reviewed. Seventeen eyes underwent trabeculectomy with MMC, and 24 eyes underwent Ahmed valve implantation.
Outcomes included postoperative intraocular pressure IOP , percent reduction from preoperative IOP, postoperative number of medications, time to failure, and complications. Cumulative success at 1 year was Mean time to failure was 8. Complications in both groups were typically rare and self-limited, with recurrent inflammation being most common.
Although both trabeculectomy with MMC and Ahmed valve implantation are reasonable surgical options in the management of uncontrolled uveitic glaucoma, Ahmed valve implantation was associated with higher cumulative success rate at 1 year and a longer mean time to failure.
First report on a human percutaneous transluminal implantation of a self-expanding valve prosthesis for interventional treatment of aortic valve stenosis. Percutaneous aortic valve replacement is a new technology for the treatment of patients with significant aortic valve stenosis.
We present the first report on a human implantation of a self-expanding aortic valve prosthesis, which is composed of three bovine pericardial leaflets inserted within a self-expanding nitinol stent. The year-old woman presented with severe symptomatic aortic valve stenosis mean transvalvular gradient of 45 mmHg; valve area of 0. Surgical valve replacement had been declined for the patient because of comorbidities, including previous bypass surgery. A retrograde approach via the common iliac artery was used for valve deployment.
The contralateral femoral vessels were used for a temporary extracorporal circulation, unloading the left ventricle during the actual stent expansion. Clinical, hemodynamic, and echocardiographic outcomes were assessed serially during the procedure.
Clinical and echocardiographic follow-up at day 1, 2, and 14 post procedure was performed to evaluate the short-term outcome. The prosthesis was successfully deployed within the native aortic valve , with accurate and stable positioning and with no impairment of the coronary artery or vein graft blood flow. The clinical status has then significantly improved. These results remained unchanged up to the day 14 follow-up.
This case report demonstrates a successful percutaneous implantation of a self-expanding aortic valve prosthesis with remarkable functional and clinical improvements in the acute and short-term outcome.
Copyright c Wiley-Liss, Inc. Small sodium valve design and operating experience.

Proving test on the reliability for nuclear valves. Since valves are the most common components, they could be the most frequent causes of troubles in nuclear power plants.
This proving test, therefore, has an important meaning to examine and verify the reliability of various valves under simulating conditions of abnormal and transient operations of the nuclear power plant. The test was performed mainly for the various types and pressure ratings of valves which were used in the primary and secondary systems in BWR and PWR nuclear power plants and which had major operating or safety related functions in those nuclear power plants. The results of the proving test, confirmed for more than four years, showed relatively favourable performance of the tested valves.
It is concluded that performances of valves including operability, seat sealing and structural integrity were proved under the thermal cycling, vibration and pipe reaction load conditions. Operating functions during and after accident such as loss of coolant accident were satisfactory.
From these results, it was considered that the purpose of this proving test was satisfactorily fulfilled. Several data accumulated by the test would be useful to get better reliability if it was evaluated with the actually experienced data of valves in the nuclear power plants. Nogami, K.
Cavitation guide for control valves. This guide teaches the basic fundamentals of cavitation to provide the reader with an understanding of what causes cavitation, when it occurs, and the potential problems cavitation can cause to a valve and piping system. The guide provides a method for predicting the cavitation intensity of control valves , and how the effect of cavitation on a system will vary with valve type, valve function, valve size, operating pressure, duration of operation and details of the piping installation.
The guide defines six cavitation limits identifying cavitation intensities ranging from inception to the maximum intensity possible. The intensity of the cavitation at each limit Is described, including a brief discussion of how each level of cavitation influences the valve and system. Examples are included to demonstrate how to apply the method, including making both size and pressure scale effects corrections. Methods of controlling cavitation are discussed providing information on various techniques which can be used to design a new system or modify an existing one so it can operate at a desired level of cavitation.
Aortic valve bypass. In aortic valve bypass AVB a valve -containing conduit is connecting the apex of the left ventricle to the descending aorta. Candidates are patients with symptomatic aortic valve stenosis rejected for conventional aortic valve replacement AVR or transcatheter aortic valve implantation TAVI. Acoustic valve leak detection in nuclear plants. Internal valve leakage is a hidden energy loss and can cause or prolong a forced outage.
Recent advances in acoustic detection of internal valve leakage have reduced piping system maintenance costs, unnecessary downtime, and energy waste. Extremely short payback periods have been reported by plants applying this technology to preventive maintenance, troubleshooting, energy conservation and outage planning. Sensors temporarily attached to the outside of valves and connected to the instruments detect ultrasonic acoustic emissions which are characteristic of internal valve leakage.
Since the sensors are attached to the outside of the valves , the time and expense of dismantling the valves or removing them from the systems are eliminated. This paper describes the instrumentation and specific applications to nuclear plant valves , including independent verification of initial findings. Guidelines for potential users, including instrumentation selection, training requirements, application planning, and the choice of in-house versus contract services are discussed.
Periodontitis is an infectious disease that affects the support tissue of the teeth and it is associated with different systemic diseases, including cardiovascular disease. Microbiological studies facilitate the detection of microorganisms from subgingival and cardiovascular samples. To describe the cultivable periodontal microbiota and the presence of microorganisms in heart valves from patients undergoing valve replacement surgery in a clinic in Cali.
We analyzed 30 subgingival and valvular tissue samples by means of two-phase culture medium, supplemented blood agar and trypticase soy agar with antibiotics. Conventional PCR was performed on samples of valve tissue. Conventional PCR did not return positive results for oral pathogens and bacterial DNA was detected only in two samples. Periodontal microbiota of patients undergoing surgery for heart valve replacement consisted of species of Gram-negative bacteria that have been associated with infections in extraoral tissues.
However, there is no evidence of the presence of periodontal pathogens in valve tissue, because even though there were valve and subgingival samples positive for Gram-negative enteric bacilli, it is not possible to maintain they corresponded to the same phylogenetic origin. Early Outcomes of Sutureless Aortic Valves. The potential advantages of sutureless aortic prostheses include reducing cross-clamping and cardiopulmonary bypass CPB time and facilitating minimally invasive surgery and complex cardiac interventions, while maintaining satisfactory hemodynamic outcomes and low rates of paravalvular leakage.
The current study reports our single-center experience regarding the early outcomes of sutureless aortic valve implantation. Methods: Between October and June , 65 patients scheduled for surgical valve replacement with symptomatic aortic valve disease and New York Heart Association function of class II or higher were included to this study.
Results: The mean age of the patients was Forty-four patients The average preoperative left ventricular ejection fraction was The CPB time was The intubation time was 8. The mean quantity of drainage from chest tubes was The hospital mortality rate was 3. A total of five patients 7. The mean follow-up time was Conclusion: In the last few years, several models of valvular sutureless bioprostheses have been developed.
The present study evaluating the single-center early outcomes of sutureless aortic valve implantation presents the results of an innovative surgical technique, finding that it resulted in appropriate hemodynamic conditions with acceptable ischemic time. In elderly high-risk surgical patients, sutureless aortic valve replacement AVR should be an alternative to standard AVR.
Between October and June , 65 patients scheduled for surgical valve replacement with symptomatic aortic valve disease and New York Heart Association function of class II or higher were included to this study. The mean age of the patients was In the last few years, several models of valvular sutureless bioprostheses have been developed. Steam turbine power plant having improved testing method and system for turbine inlet valves associated with downstream inlet valves preferably having feedforward position managed control.
A throttle valve test system for a large steam turbine functions in a turbine control system to provide throttle and governor valve test operations. The control system operates with a valve management capability to provide for pre-test governor valve mode transfer when desired, and it automatically generates feedforward valve position demand signals during and after valve tests to satisfy test and load control requirements and to provide smooth transition from valve test status to normal single or sequential governor valve operation.
A digital computer is included in the control system to provide control and test functions in the generation of the valve position demand signals. Transcatheter aortic valve replacement. Transcatheter aortic valve replacement TAVR is surgery to replace the aortic valve. Minimally invasive aortic valve replacement. In this descriptive prospective study, we evaluate the outcomes of surgery in 98 patients who were scheduled to undergo minimally invasive aortic valve replacement.
These patients were compared with a group of 50 patients who underwent scheduled aortic valve replacement through a full sternotomy The aortic cross-clamp and perfusion times were significantly different across all groups P replacement The "extended mini-aortic valve replacement" operation, on the other hand, is a risky procedure that should Magnetically operated check valve.
A magnetically operated check valve is disclosed. The valve is comprised of a valve body and a movable poppet disposed therein. A magnet attracts the poppet to hold the valve shut until the force of fluid flow through the valve overcomes the magnetic attraction and moves the poppet to an unseated, open position.
The poppet and magnet are configured and disposed to trap a magnetically attracted particulate and prevent it from flowing to a valve seating region. Pulmonary valve disruption in patients with tetralogy of Fallot and congenital pulmonary stenosis often results in pulmonary insufficiency, right ventricular dilation, and tricuspid valve regurgitation. Management of functional tricuspid regurgitation at the time of subsequent pulmonary valve replacement remains controversial.
Our aims were to 1 analyze tricuspid valve function after pulmonary valve replacement through midterm follow-up and 2 determine the benefits, if any, of concomitant tricuspid annuloplasty. Thirty-five patients with tetralogy of Fallot or congenital pulmonary stenosis were analyzed.
All patients had been palliated in childhood by disrupting the pulmonary valve , and all patients had at least moderate tricuspid valve regurgitation at the time of subsequent pulmonary valve replacement. Preoperative and serial postoperative echocardiograms were analyzed.
Pulmonary and tricuspid regurgitation, along with right ventricular dilation and dysfunction were scored as 0 none , 1 mild , 2 moderate , and 3 severe. Right ventricular volume and area were also calculated. Comparisons were made between patients who underwent pulmonary valve replacement alone and those who underwent concomitant tricuspid valve annuloplasty. At 1 month after pulmonary valve replacement, there were significant reductions in pulmonary valve regurgitation mean 3 vs 0.
However, at latest follow-up mean 7. In patients with at least moderate tricuspid valve regurgitation, significant improvement in tricuspid valve function and right ventricular size occurs in the first. What Is Heart Valve Surgery? Most valve replacements involve the aortic Tricuspid valve and mitral valves. The aortic valve separates This is called incompetence, insufficiency or regurgitation. What Is Heart Valve Disease? Biological valves are made from pig, cow, or human Ministernotomy: A preliminary experience in heart valve surgery.
The last decade of the 20th century brought up a significant development in the field of minimally invasive approaches to the valvular heart surgery. Potential benefits of this method are: good esthetic appearance, reduced pain, reduction of postoperative hemorrhage and incidence of surgical site infection, shorter postoperative intensive care units ICU period and overall in-hospital period.
Partial upper median sternotomy currently presents as a state-of-the art method for minimally invasive surgery of cardiac valves. The aim of this study was to report on initial experience in application of this surgical method in the surgery of mitral and aortic valves.
The study was designed and conducted in a prospective manner and included all the patients who underwent minimally invasive cardiac valve surgery through the partial upper median sternotomy during the period November - August We analyzed the data on mean age of patients, mean extubation time, mean postoperative drainage, mean duration of hospital stay, as well as on occurance of postoperative complications postoperative bleeding, surgical site infection and cerebrovascular insult.
During the observed period, in the Institute for Cardiovascular Diseases of Vojvodina, Clinic for Cardiovascular Surgery, 17 ministernotomies were performed, with 14 aortic valve replacements Mean age of the patients was Mean extubation time was Mean duration of hospital stay was Mean postoperative drainage was Postoperative complications included : bleeding 5. One patient 5. Partial upper median sternotomy represents. Partial upper median stemotomy currently presents as a state-of-the art method for minimally invasive surgery of cardiac valves.
The study was designed and conducted in a prospective manner and included all the patients who underwent minimally invasive cardiac valve surgery through the partial upper median stemotomy during the period November - August Partial upper median sternotomy represents the optimal surgical method for the interventions on the. Turbulence downstream of subcoronary stentless and stented aortic valves. Regions of turbulence downstream of bioprosthetic heart valves may cause damage to blood components, vessel wall as well as to aortic valve leaflets.
Stentless aortic heart valves are known to posses several hemodynamic benefits such as larger effective orifice areas, lower aortic transvalvular pressure difference and faster left ventricular mass regression compared with their stented counterpart.
Whether this is reflected by diminished turbulence formation, remains to be shown. We implanted either stented pericardial valve prostheses Mitroflow , stentless valve prostheses Solo or Toronto SPV in pigs or they preserved their native valves. Following surgery, blood velocity was measured in the cross sectional area downstream of the valves using 10MHz ultrasonic probes connected to a dedicated pulsed Doppler equipment. We found no difference in maximum RNS measurements between any of the investigated valve groups.
We, thus, found no advantages for the stentless aortic valves compared with stented prosthesis in terms of lower maximum or mean RNS values. Native valves have a significantly lower mean RNS value than all investigated bioprostheses. Butterfly valve torque prediction methodology.
This paper presents the methodology that will be used by utilities to calculate the dynamic torque requirements for butterfly valves. The total dynamic torque at any disc position is the sum of the hydrodynamic torque, bearing torque which is induced by the hydrodynamic force , as well as other small torque components such as packing torque. The hydrodynamic torque on the valve disc, caused by the fluid flow through the valve , depends on the disc angle, flow velocity, upstream flow disturbances, disc shape, and the disc aspect ratio.
The butterfly valve model provides sets of nondimensional flow and torque coefficients that can be used to predict flow rate and hydrodynamic torque throughout the disc stroke and to calculate the required actuation torque and the maximum transmitted torque throughout the opening and closing stroke. The scope of the model includes symmetric and nonsymmetric discs of different shapes and aspects ratios in compressible and incompressible fluid applications under both choked and nonchoked flow conditions.
The model features were validated against test data from a comprehensive flowloop and in situ test program. These tests were designed to systematically address the effect of the following parameters on the required torque: valve size, disc shapes and disc aspect ratios, upstream elbow orientation and its proximity, and flow conditions.
The applicability of the nondimensional coefficients to valves of different sizes was validated by performing tests on in. The butterfly valve model torque predictions were found to bound test data from the flow-loop and in situ testing, as shown in the examples provided in this paper. Selective Laser Melting SLM was utilized to fabricate a liquid hydrogen valve housing typical of those found in rocket engines and main propulsion systems.
The SLM process allowed for a valve geometry that would be difficult, if not impossible to fabricate by traditional means. Several valve bodies were built by different SLM suppliers and assembled with valve internals. The assemblies were then tested with liquid nitrogen and operated as desired.
One unit was also burst tested and sectioned for materials analysis. The design, test results, and planned testing are presented herein. In total, consecutive patients with either aortic valve disease or atrioventricular valve disease underwent minimally invasive valve surgery MIVS at our institution between 1 February and 31 March MI-AVS was performed in patients mean age SC was required in 3.
Neurological deficit occurred in 1 0. MIVS is increasingly being recognized as the 'gold-standard' for surgical valve interventions in the context of rapidly expanding catheter-based technology and increasing. Bentall procedure using cryopreserved valved aortic homografts: mid- to long-term results. The mean follow-up was 34 months months. Pump having pistons and valves made of electroactive actuators.
The present invention provides a pump for inducing a displacement of a fluid from a first medium to a second medium, including a conduit coupled to the first and second media, a transducing material piston defining a pump chamber in the conduit and being transversely displaceable for increasing a volume of the chamber to extract the fluid from the first medium to the chamber and for decreasing the chamber volume to force the fluid from the chamber to the second medium, a first transducing material valve mounted in the conduit between the piston and the first medium and being transversely displaceable from a closed position to an open position to admit the fluid to the chamber, and control means for changing a first field applied to the piston to displace the piston for changing the chamber volume and for changing a second field applied to the first valve to change the position of the first valve.
Controllable valve in a nuclear reactor system. The quick-acting gate valve of the PWR is opened and closed by means of two pistons and live steam. One of the pistons is connected to the valve disk by a piston rod which is concentrically lead into another hollow piston rod being connected to the second piston. Stops limit the strokes of the two pistons.
GL [de. Microfluidic sieve valves. Sieve valves for use in microfluidic device are provided. The valves are useful for impeding the flow of particles, such as chromatography beads or cells, in a microfluidic channel while allowing liquid solution to pass through the valve. The valves find particular use in making microfluidic chromatography modules.
Rotary pneumatic valve. A rotary pneumatic valve which is thrust balanced and the pneumatic pressure developed produces only radial loads on the valve cylinder producing negligible resistance and thus minimal torque on the bearings of the valve.
The valve is multiplexed such that at least two complete switching cycles occur for each revolution of the cylinder spindle. Mitral Valve Stenosis. A defective heart valve fails to either open or close fully. Risk factors Mitral valve stenosis is less common today than it once was because the most common cause, Aortic Valve Stenosis. Calcium buildup on the valve.
With age, heart valves may accumulate deposits of calcium aortic valve Remote actuated valve implant. Valve implant systems positionable within a flow passage, the systems having an inlet, an outlet, and a remotely activatable valve between the inlet and outlet, with the valves being operable to provide intermittent occlusion of the flow path. A remote field is applied to provide thermal or magnetic activation of the valves. Outcomes in nonagenarians after heart valve replacement operation.
Changes in the age profile of the United Kingdom population and improvements in preoperative and postoperative care have resulted in increasing numbers of very elderly patients undergoing heart valve replacement HVR operations.
Although HVR operations in nonagenarians are relatively uncommon, the demand for cardiac operations in this age group may increase over time. Outcomes after HVR operations in nonagenarians have not been well described yet.
Therefore, the aim of this study was to determine outcomes in terms of early mortality and long-term survival in 35 nonagenarians after HVR operation. Data from the United Kingdom Heart Valve Registry were analyzed and nonagenarian patients were identified. Additional analyzed data include gender, valve position, valve type, valve size, operative priority, follow-up time, and date and cause of death. Kaplan-Meier actuarial curves were calculated to determine accurate day mortality and long-term survival.
On average five HVR operations are performed annually in the United Kingdom in nonagenarians with equal numbers of males and females. Fourteen patients died within the review period; mean time to death was days. HVR operations in nonagenarians carry a significantly higher risk of early mortality and reduced long-term survival.
Despite increases in the age profile of the population, elective HVR operation with patients aged 90 years or older is likely to remain an infrequent surgical procedure reserved for very carefully selected patients.
Impact of pannus formation on hemodynamic dysfunction of prosthetic aortic valve : pannus extent and its relationship to prosthetic valve motion and degree of stenosis. Although pannus is an important cause of prosthetic valve dysfunction, the minimum pannus size that can induce hemodynamic dysfunction has not yet been determined.
This study investigated the correlation between the limitation of motion LOM of the prosthetic valve and pannus extent and determined the pannus extent that could induce severe aortic stenosis. This study included 49 patients who underwent mechanical aortic valve replacement AVR and showed pannus on cardiac computed tomography CT.
Pannus width, ratio of pannus width to valve diameter, pannus area, effective orifice area, encroachment ratio by pannus, pannus involvement angle and percent LOM of mechanical valves were evaluated on CT. Transvalvular peak velocity TPV and transvalvular pressure gradient TPG were measured by transesophageal echocardiography to determine the degree of aortic stenosis. The relationship between percent LOM of the prosthetic valve and pannus extent and the cut-off of pannus extent required to induce severe aortic stenosis were evaluated.
Leakage characterization of a piloted power operated relief valve. The valves are fail closed globe valves which means that power is required to open the valves and, on loss of power, the valves close. There are two ways to operate the PORVs. The more common way is to directly couple the disc to an actuator via a disc-stem assembly. The type of design is not the object of this paper.
The other and less common way of operating a PORV is by piloting the main valve such that the opening or closing of a pilot valve opens and closes the main valve. This is the design of interest. In most plants, the PORVs are installed with a water loop seal while in some plants no water loop seals are used. It is generally accepted that loop seal installation minimizes valve seat leakage.
In non-loop seal installation, the valve seat is exposed to steam which increases the potential for seat leakage. This paper describes the results of some tests performed with nitrogen and steam to characterize the leakage potential of a pilot operated PORV. The test results were compared with seat leakage tests of check valves to provide insight on the leakage testing of pilot operated valves and check valves. Aortic valve replacement with the Biocor PSB stentless xenograft.
The midterm clinical results after aortic valve replacement with the Biocor PSB stentless xenograft on all patients operated between October and October were reviewed. There were 5 late deaths due to cardiac cause 2 , cancer 2 , and pulmonary embolism 1 patient. No cases of valve regurgitation greater than mild were recorded at follow-up.
Assessment of New York Heart Association functional class demonstrated a significant improvement 2. All patients were free from anticoagulation. Aortic valve replacement using the Biocor PSB stentless xenograft offers excellent midterm survival, negligible valve deterioration, and a very low rate of valve -related events, which are comparable to estimates reported with other models of stentless xenografts and currently available stented xenografts.
Hemodynamic performance is favorable and. Full Text Available We present a novel 3D printed multimaterial microfluidic proportional valve. The microfluidic valve is a fundamental primitive that enables the development of programmable, automated devices for controlling fluids in a precise manner.
We discuss valve characterization results, as well as exploratory design variations in channel width, membrane thickness, and membrane stiffness. Compared to previous single material 3D printed valves that are stiff, these printed valves constrain fluidic deformation spatially, through combinations of stiff and flexible materials, to enable intricate geometries in an actuated, functionally graded device. Research presented marks a shift towards 3D printing multi-property programmable fluidic devices in a single step, in which integrated multimaterial valves can be used to control complex fluidic reactions for a variety of applications, including DNA assembly and analysis, continuous sampling and sensing, and soft robotics.
Measurement of opening and closing angles of aortic valve prostheses in vivo using dual-source computed tomography: Comparison with those of manufacturers' in 10 different types. The aims of this study were to compare opening and closing angles of normally functioning mechanical aortic valves measured on dual-source computed tomography CT with the manufacturers' values and to compare CT-measured opening angles according to valve function.
A total of patients with 10 different types of mechanical aortic valves , who underwent dual-source cardiac CT, were included. Opening and closing angles were measured on CT images. Agreement between angles in normally functioning valves and the manufacturer values was assessed using the interclass coefficient and the Bland-Altman method. CT-measured opening angles were compared between normal functioning valves and suspected dysfunctioning valves.
The CT-measured opening angles of normally functioning valves and manufacturers' values showed excellent agreement for seven valve types intraclass coefficient [ICC], 0. The mean differences in opening angles between the CT measurements and the manufacturers' values were 1. Iryna Schmeil Prof. Strebhardt Prof. Thomas Karn Dr. Uwe Holtrich.

Wozu gibt es eine Notfallambulanz, wenn Patienten abgewimmelt werden? Kann die Klinik absolut nicht weiter empfehlen. Diese Diagnose stellte die Klinik nur anhand der Tatsache das meine Tochter rechnerisch zu dem Zeitpunkt in der Woche war. Der normal gestiegene Blutwert vom HCG wurde nicht beachtet. Meinung einholen wollte, sah man einen putzmunteren Embryo mit Herzschlag.
Warum wird sich schon beim 1. Ultraschall in der Klinik widersprochen. Aussage des Arztes: "Das sieht eher nach 5. Woche aus. Wir jedenfalls betreten diese Klinik nicht mehr. Ich hatte als Patient den Eindruck, dass es nur um die Opfer-Statistik ging.
Fazit Man hatte mir Honig ums Maul geschmiert damit ich der op zustimme und nachher nichts eingehalten. Mein Fehler dass ich keine kompetente Zweitmeinung eingeholt habe. Die Geburt war in Ordnung alles prima. Wie kommt's? Ich bin voll und ganz zufrieden!!! Einziges Kontra man musste sehr lang auf Untersuchungen und Visite warten.

Wurde hier 2x an der Brust operiert Brustkrebs und wurde super ver- und umsorgt. Aus meiner Brust wurden insgesamt 3,8 cm herausgenommen und der behandelnde Arzt Chef- und Oberarzt haben die Brust wieder super aufgebaut. Auch die Versorgung nach der OP war einfach super. Ich kann dieses Brustzentrum nur empfehlen. Es wurden alle meine Fragen beantwortet und es war keinem zuviel.
Man hat hier den Eindruck, dass der Mensch wichtiger ist als Geld. Auch die Nachversorgung in der Onkologie Chemo ist sehr empfehlenswert.
