【 摘 要 】

A 70-year-old man underwent mitral valve replacement using a porcine bioprosthesis for infective endocarditis. Transthoracic echocardiography revealed thickened leaflets with increased transprosthetic pressure gradient and new regurgitation, 6 months after surgery. He was followed up medically with the diagnosis of early valve degeneration. He ultimately presented with worsening orthopnea 13 months after surgery. Transesophageal echocardiography revealed an immobile round mass attached to the ventricular aspect of the leaflets, which hampered valve opening, suggesting bioprosthetic valve thrombosis. Anticoagulation with heparin and warfarin were effective and transthoracic echocardiography showed normal transprosthetic pressure gradient and disappearance of regurgitation 2 months later.
