BACKGROUND Few published studies address the survival of kidney transplantation patients after valve surgery, and none address relative outcomes related to tissue versus nontissue prosthesis. This study aimed to assess survival of US kidney transplantation patients after cardiac valve replacement and to compare associations of valve selection. METHODS AND RESULTS Of 1 698 706 patients in the ...

An acoustic plate-valve resonator is developed and optimized to maximize absorption by enhancing the Helmholtz resonance with coincident structural vibrations of plate-valve. The current research initially examines concept experimentally a 3D printed valve. Then use analytical numerical modeling, analysis performed, which allows eigenmodes eigenfrequencies be determined. When properties are mod...

background total correction of tetralogy of fallot (tof) anomaly in early childhood has been practiced in many centers with good results, but in some of patients after few years sever pulmonary valve insufficiency occurred. materials and methods at a cross- sectional study from january 2015 to january 2016, 10 patients who had history of primary repair of tof with free pulmonary insufficiency (...

repair of the mitral valve is the treatment of choice for mitral valve regurgitation when the anatomy is favorable. it is well known that mitral valve repair enjoys better clinical and functional results than any other type of valve substitute. this fact is beyond doubt regardless of the etiology of the valve lesion and is of particular importance in degenerative diseases. this review analyzes ...

mitral valve replacement (mvr) is usually performed in two methods of running and interrupted suturing. in running method, the suturing of the valve is usually with some traction on the annulus and also there is a risk of aortic valve injury. this study was conducted to evaluate a new technique for suturing to avoid these complications and decrease the time of cardiac arrest. one hundred and se...

AIMS Pulmonary atresia with intact ventricular septum (PA-IVS) is a complex congenital heart malformation with multitude therapeutic approaches. Recently, balloon valvotomy has been used as an alternative to primary surgery. This study aimed to identify echocardiographic markers of balloon dilation success in PA-IVS. METHODS AND RESULTS The echocardiograms of 26 patients diagnosed with PA-IVS...

BACKGROUND Because of risk of outlet strut fracture, prophylactic replacement should be considered for Björk-Shiley convexo-concave (BScc) valve recipients. We assessed the effects of epidemiological and decision-analytic guidelines on actual BScc valve replacement. METHODS AND RESULTS We performed a retrospective cohort study including all 2263 Dutch BScc patients with a mean follow-up of 11...

  Introduction: Aortic valve sclerosisis considered as a manifestation of coronary atherosclerosis. Recent studies demonstrated an association between aortic valve sclerosis and obstructive coronary artery disease. The purpose of this study was to evaluatethe correlation betweenaortic valve sclerosis andobstructive coronary artery disease and the extent of coronary artery disease in patients ho...

OBJECTIVE Compared with reoperative aortic valve replacement for nonendocarditic causes, the contemporary risk and long-term outcomes of reoperation for aortic prosthetic valve endocarditis are ill-defined. METHODS Between December 1994 and April 2008, 313 patients underwent reoperative aortic valve replacement, of whom 152 (48.6%) had prosthetic valve endocarditis. Mean follow-up was 6.5 ± 0...
