Proximal aortic measurements in the parasternal long-axis view. The maximum and minimum measurements were taken from inner edge to inner edge: (1) aortic valve “annulus” at the hinge points of the leaflets; (2) aortic root at the largest diameter within the sinuses of Valsalva; (3) sinotubular junction at the transition point from sinus to tubular aorta; (4) ascending aorta at the level of the right pulmonary artery (RPA). AO, Aorta; LA, left atrium; LV, left ventricle.
