Transesophageal echocardiography (TEE) provides high-resolution images of the mitral valve apparatus, permitting detailed evaluation of its structure and function. Mitral valve evaluation is invaluable during mitral valve repair surgery, providing insight into the mechanism of valve dysfunction and formulation of a plan for repair. TEE provides immediate detection of inadequate repair after bypass and allows correction during the same operative setting. Intraoperative TEE is a valuable tool for improving patient outcome and offers the cardiovascular anesthesiologist a role in perioperative surgical decisions.
