Abstract 13046: Real-Time Three-Dimensional Transesophageal Echocardiography Can Accurately Detect True Lumen Originated Coronary Arteries in Patients with Acute Type A Aortic Dissection
Purpose: The aim of this study was to test the hypothesis whether real-time three-dimensional transesophageal echocardiography (RT3DTEE) can detect true lumen originated coronary arteries in patients with acute type A aortic dissection (AAD).
Methods: We enrolled 51 consecutive patients who underwent intraoperative echocardiography by RT3DTEE (iE33, Philips Medical Systems, USA) during emergency surgery for AAD. We detected the position of the ostia of the coronary arteries by conventional 2D echocardiography and by analysis of 3D dataset, and compared them with surgical findings.
Results: RT3DTEE could successfully detect the ostia of the coronary arteries. In detecting the true lumen originated coronary arteries, 3D analysis was significantly more accurate than conventional 2D imaging (Table).
Conclusion: RT3DTEE is a new noninvasive approach to assess critical risks of emergency surgery for AAD.
