Dynamic annular geometry and function in patients with mitral regurgitation: Insight from three-dimensional annular tracking
Image Interpretation, Computer-Assisted
Mitral Valve Insufficiency
Mitral Valve Prolapse
Patients with MR have significant MA enlargement, irrespective of MR etiology. In contrast to functional MR, patients with MR secondary to leaflet prolapse have the largest annular remodeling-almost 80% increase in area-and yet have preserved annular function and dynamicity. These findings may influence surgical repair technique.
