Figure 2. Graphical summary of measured aortic valve data. A: mean coaptation surface between two adjacent leaflets of 82 mm2. Mean free margin to sinutubular plane angle of 37°, mean leaflet belly to annular plane of 24° and mean angle between sinutubular and annular planes of 8° B: angles occupied by individual leaflets relative to sinutubular plane (left 122°, right 122°and noncoronary 116°). Also note the relative heights of commissures, RN commissure being the highest.
