title: Intraoperative real time three-dimensional transesophageal echocardiographic measurement of hemodynamic, anatomic and functional changes after aortic valve replacement.
abstract: The traditional intraoperative two-dimensional transesophageal echocardiography (2DTEE) has limitations in measuring left ventricular ejection fraction (LVEF) because measurements rely on geometric assumptions. The availability of online software and real time three-dimensional transesophageal echocardiography (RT3D-TEE) makes intraoperative LVEF measurements fast and easy. This is the first report of intraoperative measurement of LVEF and aortic valve area (AVA) by RT3-DTEE in a patient who received transcatheter-based transapical aortic valve implantation.
