Intravalvular regurgitation of the mitral bioprosthetic valve detected by intraoperative transesophageal echocardiography -A case report-

Abstract

Intraoperative transesophageal echocardiography (IOTEE) is an invaluable diagnostic method for management of cardiac surgical patients, including patients undergoing valve replacement surgery. We report a patient who underwent reoperation for mitral valve replacement due to intravalvular regurgitation following mitral valve replacement with a bioprosthetic valve. The condition was detected by IOTEE and caused by suture entrapment.
