Impact of intraoperative transesophageal echocardiography in cardiac and thoracic aortic surgery: Experience in 1011 cases

Background: Although intraoperative transesophageal echocardiography (IOTEE) has been widely used in cardiovascular surgery, the exact incidence of abnormalities detected by IOTEE in each type of surgical procedure is still unclear. The aim of this study was to review our experiences of IOTEE, in patients who underwent different types of cardiovascular surgery and to evaluate the clinical usefulness of IOTEE. Methods and results: Our database of 1011 consecutive patients, who underwent cardiovascular surgery and IOTEE monitoring was reviewed. The incidence of abnormal findings was 115 of 1011 patients (11.4%), and the highest incidence was the appearance of new watt motion abnormalities after cardiopulmonary bypass. These findings influenced surgical decision-making in 59 of the evaluated 1011 patients (5.8%). Conclusions: IOTEE provides important intraoperative and postoperative information that may influence surgical decision-making in various cardiovascular surgeries.
