Text Box: INTRAOPERATIVE TRANSESOPHAGEAL ECHO-CARDIO-GRAPHY IN CHILDREN UNDERGOING VALVE REPAIR Zhang Y-Q, Sun K, Chen S-B, et al Shanghai Children’s Medical Center, Shanghai, China Objective: To assess the value of intraoperative transesophageal echocardiography (TEE) in children undergoing valve repair. Methods: Intraoperative TEE was performed in 44 children undergoing valve repair. Results: Intraoperative TEE added or modified preoperative diagnosis in 8/44 (18.2%) cases, and altered the planned surgical procedure in 3 cases (6.82%). Moderate or severe valvular regurgitation were shown in 6 patients by post-bypass TEE, 4 patients needed second cardiopulmonary bypass (CPB) for prosthetic valve replacement, 2 patients died. Perivalvular leak was found in 1 of 6 patients undergoing prosthetic valve replacement and returned for CPB and repair. Conclusions: Intraoperative TEE is a safe and effective monitoring technique, and should be performed routinely during valve repair. 1853
