Assessment of aortic annular plane. a Aortoventricular centreline is created manually. b Based on a centreline, double-oblique MPR images are created at the pre-selected level of the basal annular plane (AA) with all the AA measurements obtained at this level. c The 3D volume-rendering reformats of the aortovalvular complex are generated based on the same centreline. d Manual measurements of maximum and minimum aortic annulus diameter and perimeter
