Abstract:
Objective To explore the utility of intraoperative transesophageal echocardiography (TEE) in robotic mitral valve repair (MVR) with the da Vinci system. Methods Intraoperative TEE was performed in 24 patients undergoing robotic MVR for severe degenerative mitral regurgitation (MR)between September 2007 and February 2010. Before cardiopulmonary bypass (CPB) ,TEE was performed to document the mechanism and location of degenerative MR. During establishment of peripheral CPB, TEE was used to guide placement of the cannulae in the inferior vena cava (IVC),superior vena cava (SVC),and ascending aorta (AAO). After weaning from CPB, TEE was performed to evaluate the effect of the procedure. Results Accuracy of TEE was 93.1% for the mechanism of degenerative MR, and 98.6% for the localization of the prolapsed leaflets. All the cannulae in the SVC,IVC and AAO were located in correct position. In all patients, TEE confirmed successful repair with no residual insufficiency and no procedurerelated complications. Conclusions In robotic MVR, TEE have important roles as follows: providing the reliable diagnostic information before CPB, guiding placement of the cannulae in the IVC, SVC, and AAO correctly during establishment of peripheral CPB determining the competency of MVR immediately after CPB. TEE is important for robotic MVR.
