Abstract

A 72-year-old man was admitted to our hospital because of dyspnea. He had a history of cardiac resynchronization therapy for congestive heart failure due to dilated cardiomyopathy 6 months previously. Echocardiography revealed severe functional mitral regurgitation which had been mild 6 months before. Because medical treatment was ineffective, on-pump beating mitral valve replacement using a bioprosthesis was performed to prevent reperfusion injury. The patient was easily weaned from cardiopulmonary bypass with low-dose inotropic support and scheduled intra-aortic balloon pump. Then, he was discharged in a good condition on the 37th postoperative day. Beating mitral valve replacement seems to be a good surgical option for patients with poor left ventricular function.
