摘要 |
A remodeling mitral annuloplasty ring with a reduced anterior-to-posterior dimension to restore coaptation between the mitral leaflets in mitral valve insufficiency (IMVI). The ring has a generally oval shaped body with a major axis perpendicular to a mirror axis, both perpendicular to a blood flow axis. An anterior section lies between anteriolateral and posteriomedial trigones, while a posterior section defines the remaining ring body and is divided into P1, P2, and P3 segments corresponding to the three scallops of the same nomenclature in the posterior leaflet of the mitral valve. The anterior-to-posterior dimension of the ring body is reduced from conventional rings; such as by providing, in atrial plan view, a pulled-in P3 segment. Viewed another way, the convexity of the P3 segment is less pronounced than the convexity of the P1 segment. |
