From: Complex and multilevel left ventricular outflow tract obstruction: What can 3D echocardiography add?
A case of rheumatic aortic valve disease. 2D TOE (aortic long- and short-axis views) shows reduced excursion of the cusps with characteristic doming. X-plane mode of the aortic valve at the level of its tips to get the true anatomical orifice. Multiplanar reformatting (MPR) of the 3D volume of the aortic valve and LVOT; accurate planimetered AVA and the anteroposterior and mediolateral diameters of the aortic annulus
