Catastrophic late mitral bioprosthetic thrombosis.

Although clinically significant bioprosthetic valve thrombosis is rare, it should be considered a possible cause of valve dysfunction when there is an increasing transvalvular pressure gradient after anticoagulation is terminated. We describe a rare case of bioprosthetic mitral thrombosis in a 77-year-old woman 2 years after valve replacement and a maze procedure.

Senile Cardiac Calcification Syndrome: A Rare Case of Extensive Calcification of Left Ventricular Papillary Muscle.

Extensive papillary muscle calcification is uncommon and only scarce literature about causes and the clinical significance is available, whereas small calcific deposits are common findings in elderly people and are located most commonly at the apex. Papillary muscle calcification has been associated with coronary artery disease, dilated cardiomyopathy, mitral valve disease, hypercalcemia, and increased calcium phosphate product in end stage renal disease. We reported a rare case of extensive calcification of anterolateral papillary muscle diagnosed by echocardiography and multidetector computed tomography.
