dc.description.abstractIschemic mitral regurgitation is affiliated with changes in annular dimensions as well as remodeling of the left ventricle. Undersized mitral annuloplasty (UMA), which involves implanting a titanium-based ring-like structure onto the mitral annulus, is aimed at reducing annular dimensions in order to restore leaflet coaptation and therefor correct IMR. The durability of this treatment is improved with papillary muscle approximation (PMA), in which a suture draws together the two papillary muscles that connect the mitral valve to the heart muscle, reducing the lateral separation of the papillary muscles in order to relieve tethering on the mitral leaflets to correct IMR. The participants in this investigation are retrospectively identified patients who have already undergone surgery for IMR. The purpose of this retrospective study is to investigate (1) the impact UMA has on left ventricular function and (2) whether preoperative geometry, specifically interpapillary muscle separation (IPMS), is predictive of FMR severity at 12 months after UMA.
