This report deals with a rare complication of disc-valve prosthesis in the mitral area. A significant disc poppet and struts destruction of mitral BeaU valve prostheses occurred 20 and 17 months after implantation. The resulting valve incompetence in the first case contributed to the death of the patient. The durability of Teflon prosthetic valves appears to be in question and this type of valv...

Infective endocarditis (IE) is the infection of endocardial surface heart. IE rare disease with significant complications which require early diagnosis and proper treatment for reducing morbidity mortality.IE vegetation on pulmonary valve, leaflets are uncommon. However, we have diagnosed one case infective associated Multisystem Inflammatory Syndrome in Children (MIS-C) related COVID-19. MIS-C...

BACKGROUND Specialist clinics are recommended for the assessment and follow-up of patients with heart valve disease. We sought to identify the current provision of specialist valve clinics in UK. METHODS A database of all UK National Health Service hospitals was created. An online survey was distributed to each hospital to examine the model of heart valve clinic, patient population, provision...

BACKGROUND Various complications lead to reoperation in patients who undergo prosthetic valve replacement where inflammatory process could be involved. The goals of this study were to identify risk factors that correlate with reoperation in patients with prosthetic heart valves and to investigate the relationship between reoperation and inflammatory gene polymorphisms. RESULTS The study inclu...

BACKGROUND Minimal data exist on the long-term survival of dialysis patients after cardiac valve surgery. Current practice guidelines of the American College of Cardiology/American Heart Association Task Force on the management of patients with valvular heart disease proscribe the use of bioprosthetic (tissue) valves in hemodialysis patients. METHODS AND RESULTS Dialysis patients hospitalized...

BACKGROUND AND AIM OF THE STUDY In-vitro studies on the ATS heart valve have indicated that valve opening is less in an expanding conduit than in a straight conduit. METHODS Bileaflet valve behavior was studied using a new computational fluid-structure interaction model. A three-dimensional model of the ATS valve was studied in two geometries, simulating the valve in a geometry with sudden ex...

Congenital heart valve cyst is a rare and asymptomatic condition mostly seen in the mitral and tricuspid valves (1). In some cases, surgery is required as these cysts may cause obstruction, valve dysfunction, and sometimes embolism (2, 3). We think that if a heart valve cyst is asymptomatic and does not alter valve function, periodic evaluation with echocardiography is a feasible option. Here w...

To facilitate the radiographic identification of prosthetic heart valves, radiographic silhouettes of various aortic, mitral and tricuspid valve prostheses were analyzed and shematized. Forty different prosthetic valve models (heterograft and mechanical) were obtained from seven domestic manufacturers. Each prosthesis was positioned to approximate the aortic, mitral or tricuspid valve anulus pl...

OBJECTIVES This analysis reports on the initial German multicenter experience with the JenaValve (JenaValve Technology GmbH, Munich, Germany) transcatheter heart valve for the treatment of pure aortic regurgitation. BACKGROUND Experience with transcatheter aortic valve implantation (TAVI) for severe aortic regurgitation is limited due to the risk of insufficient anchoring of the valve stent w...
