Hybrid three-dimensional renderings of all subjects at (A) baseline and after implantation of either the (B) saddle ring or the (C) Physio ring. In all cases color contouring is determined by intercommissural two-dimensional leaflet curvatures (KIC), with KICmin equal to −1.5 cm−1 and KICmax equal to 1.5 cm−1 as illustrated in panel A. Negative K represents local surface curvature concave towards the left ventricle; positive K represents local surface curvature concave towards the left atrium. The midanterior annulus (mid-AA), midposterior annulus (mid-PA), anterior commissure (AC), and posterior commissure (PC) have been labeled in each view.
