Abstract [en]

Anterior leaflet circumferential and radial curvatures were quantified in the six hearts as described in Appendix C. In brief, for each frame a best-fit plane was fit to all the anterior leaflet markers, including the trigonal hinge markers. Coordinate X-Y basis vectors were established in this plane and radial curvature was defined from the radius of a circle passing through the X-Z coordinates of radial marker triplets in this coordinate system (roughly perpendicular to the line connecting the LFT-RFT markers) and circumferential curvature defined from the radius of the circle passing through the Y-Z coordinates of circumferential marker triplets (roughly parallel to the line connecting the LFT-RFT markers). As defined in this fashion, positive curvature was concave to the LV, negative curvature was convex to the LV.
