The type and extent of mitral valve remodeling in response to ischemic mitral regurgitation may predict success/recurrence after mitral valve repair.  The authors collected 3-dimensional data from patients with ischemic MR and from patients with normal valves and analyzed the data geometrically.  Remodeling was identified by lengthening of the middle portion of A2, an increased nonplanarity angle, and an increased tenting angle of P3.
