Abstract

Transesophageal echocardiography (TEE) plays a significant role during transcatheter aortic valve implantation (TAVR). 2DTEE allows assessment of anatomy of the aortic valve, aortic root, left ventricular (LV) outflow tract, severity of the aortic valve stenosis (AS), and the presence and severity of other valve stenosis and regurgitation. Left and right ventricular size and global function as well as cardiac hemodynamics pre and post TAVR and LV regional wall motion can be assessed. Three-dimensional (3D) imaging adds significantly via accurate measurement of aortic annulus that helps select the appropriate valve size. Biplane imaging allows simultaneous assessment of target cardiac structure in two orthogonal views and provides a rapid assessment during and immediately post valve deployment by evaluating stent height, leaflet motion, and the presence and severity of paravalvular leak (PVL). 2DTEE and 3DTEE allow evaluation of mechanism of PVL that helps guide the decision regarding need for balloon post dilation of the implanted valve or valve in valve implantation.
