BACKGROUND Cardiovascular Magnetic Resonance is often used to evaluate patients after heart valve replacement. This study systematically analyses the influence of heart valve prostheses on phase contrast measurements in a phantom trial. METHODS Two biological and one mechanical aortic valve prostheses were integrated in a flow phantom. B0 maps and phase contrast measurements were acquired at ...

BACKGROUND Several centers favor replacing a diseased native heart valve with a tissue rather than a mechanical prosthesis, even in younger adult patients. However, long-term data supporting this approach are lacking. We examined the survival implications of selecting a tissue versus a mechanical prosthesis at initial left-heart valve replacement in a cohort of adults <60 years of age who were ...

From 1975 to 1979, 540 patients undergoing valve replacement were entered into a randomized trial and received either a Bjdrk-Shiley (273 patients) or a porcine heterograft prosthesis (initially a Hancock valve [107 patients] and later a Carpentier-Edwards prosthesis [ 160 patients]). Two hundred and sixty-two patients required mitral valve replacement, 210 required aortic valve replacement, 60...

Heart valve replacement with a mechanical valve requires lifelong anticoagulation. Guidelines currently recommend using a vitamin K antagonist (VKA) such as warfarin. Given the teratogenic effects of VKAs, it is often favorable to switch to heparin-derived therapies in pregnant patients since they do not cross the placenta. However, these therapies are known to be less effective anticoagulants ...

As a clinical case, we present the "portrait" of woman patient with acquired mitral valve (MV) defect against background infective endocarditis which was diagnosed during third trimester pregnancy. The underwent replacement surgery biological prosthesis "KemKor" followed by two successful deliveries. In 18 years after correction defect, she developed dysfunction therefore, endovascular transcat...

Prosthesis valve dehiscence is one of the most serious complications prosthetic valves. Despite improvements in medical and surgical treatments, prosthesis has high mortality. Due to fatality rates, early diagnosis treatment these patients required. In this case report, we presented a patient with severe mitral deficiency acute heart failure following mechanical secondary culture-negative endoc...

Nearly 15 million people in the United States suffer from either aortic or mitral valvular disease. For patients with severe and symptomatic valvular heart disease, valve replacement surgery improves morbidity and mortality outcomes. In 2009, 90,000 valve replacement surgeries were performed in the United States. This review evaluates the advantages and disadvantages of mechanical and bioprosth...

Dehiscence of the valve is a serious complication of prosthetic heart valve replacement. It has grave consequences unless promptly diagnosed and corrected by surgery. We report the case of a symptomless patient with near-complete detachment of the aortic prosthesis, diagnosed by radiography and two-dimensional echocardiography. This was confirmed at surgery and the dehisced prosthetic valve was...

MOTS CLÉS Traitement anticoagulant ; Valvulopathies ; Prothèses mécaniques Patients operated for mechanical heart valve replacement have a low rate of reintervention but suffer valve-related events due to thromboembolism and bleeding caused by anticoagulant therapy. New oral anticoagulants (NOACs) are easier to use than vitamin K antagonists and offer a good compromise between efficacy and safe...
