Abstract

The patient was a 61-year-old female. She underwent mitral valve replacement (MVR) with a 27 mm Carbomedics valve and tricuspid valve annuloplasty using the DeVega method in September 1997. She has received anticoagulant therapy by aspirin and warfarin in a nearby hospital. Because of aggravating dyspnea and chest pain after an acute upper respiratory inflammation, she was transferred to our hospital on an emergency basis on April 14, 2003. Upon admission she went into cardiogenic shock and multiple-organ failure. Biolite carbon coating prevents adhesion of thrombus or pannus on the sewing cuff of Carbomedics valve, and there were few reports of Carbomedics valve dysfunction by pannus formation. But in this case cineradiography demonstrated the prosthetic valve was fixed in the closed position. We diagnosed acute heart failure due to a stuck valve in the mitral position, and redo MVR was performed in emergency. Thrombotic pannus extended from the sewing cuff and into the orifice on the inflow and outflow sides of the valve, and fixed both leaflets in a closed position. The postoperative course was uneventful, and she was discharged on the 20th postoperative day, and now anticoagulant therapy is managed in the outpatient clinic of our hospital. A combination of cineradiography and echocardiography provides a detailed diagnosis of asymptomatic valve dysfunction. Periodical examination by a prosthetic valve specialist is necessary in order to perform adequate anticoagulant therapy, echocardiography and cineradiography after prosthetic valve replacement.
