title: [A case of prosthetic valve malfunction found by transesophageal echocardiography soon after the termination of cardiopulmonary bypass].
abstract: We present a case of mitral prosthetic valve malfunction soon after the termination of cardiopulmonary bypass. One leaflet of the St. Jude prosthetic mitral valve was found immobilized in the closed position during diastole by transesophageal echocardiography, with no abnormal hemodynamic changes. We started cardiopulmonary bypass again, and removed residual chordae. TEE is an essential tool for evaluating prosthetic valve function after the valve replacement.
