Impact of Intraoperative Transesophageal Echocardiography on Cardiac Surgical Operating Room

Abstract

To assess the usefulness of intraoperative transesophageal echocardiography (IOTEE) in a cardiac surgery department. Patients were examined with IOTEE before and after cardiopulmonary bypass. All studies were performed with a Toshiba 270 SSA model imaging device. All IOTEE examinations were performed by two cardiovascular surgery residents who are experienced in IOTEE. A total of 466 patients (239 men, 227 women) were examined by IOTEE from 2001 through 2007. Of these 182 (39%) were performed during correction of valvular pathologies, 193 (41%) during coronary operations, 34 (7%) during combined operations (either valvular or coronary bypass), 8 (1.7%) in adult congenital heart operations, 7 (1.5%) in cardiac mass operations, and the rest in other miscellaneous operations. TEE examinations performed before and after the cardiopulmonary bypass influenced surgical decisions by 14.8% and 9.0%, respectively. Decisions regarding the mitral valve were the most frequent followed by decisions regarding the tricuspid valve. IOTEE significantly affected decision making in cardiac surgery operating room. IOTEE examination must be a standard procedure for all patients undergoing cardiac surgery.
