In this case, a successful mitral valve repair was confirmed by transesophageal echocardiography (TEE) at the end of a cardiopulmonary bypass. The left ventricular vent was placed through the mitral valve to remove the air after the TEE examination, and on its way out, the left ventricular vent damaged the anterior mitral leaflet (AML). Re-examination of the valve with TEE detected the new mitral valve insufficiency. The CPB was reinstituted, and tearing of the lateral third part of the anterior mitral leaflet was found. This case emphasizes the importance of TEE in the operating room as a continuous monitor, not only to evaluate the result of the cardiac surgery, but also to detect any unpredictable events during the surgery.
