Quantitative In-Vivo Assessment of Human Mitral Valve Coaptation Area After Undersized Ring Annuloplasty Repair for Ischemic Mitral Regurgitation

Although increasing leaflet coaptation area is an intuitively obvious way to improve long-term repair durability, this study has implied that this may not be a reliable target for mitral valve repair. This study underscores the importance of a rigorous understanding of the consequences of repair techniques on mitral valve behavior, as well as a patient-specific approach to ischemic mitral regurgitation treatment within the context of mitral valve and left ventricle function.
