[Severe mixed prosthetic double-discs mitral valve dysfunction due to thrombosis - a case report]

Abstract

We reported a rare case of acute thrombosis of mechanical mitral prosthesis. A 58-year-old man underwent mitral valve replacement using St. Jude Medical mechanical valve prosthesis because of rheumatic heart disease 3 years ago. On admission he presented symptoms and signs of heart failure (NYHA class IV). Transthoracic transesophageal echocardiogram revealed mixed prosthetic mitral valve dysfunction. Disturbances of discs movements caused by thrombosis were observed. After unsuccessful thrombolytic treatment patient underwent biological mitral valve replacement.
