Figure 2
Semi-automated aortic annulus measurement. This image is achieved by scrolling the image in a multi-planar reconstruction mode to maximal aortic valve opening, aligning the aorta in an upright direction in the 2 orthogonal planes (frame A and B) and defining the annular points of aortic valve insertion. Frame C demonstrates the 2D plane of the annulus and frame D is the 3D reconstruction of the annulus.
Abbreviations:
A – anterior; AL – anterolateral; Ao – ascending aorta; Av – aortic valve; Ava – aortic valve annulus; LVot – left ventricular outflow tract; P – posterior; PM - posteromedial
