Mitral annulus dynamics early after valve repair: Preliminary observations of the effect of resectional versus non-resectional approaches
Cardiac Surgical Procedures
Mitral Valve Insufficiency
The size of the mitral annulus is reduced after repair with either surgical approach. Compared with resectional valve repair, more dynamic changes in the structure of the mitral annulus are maintained during the cardiac cycle with the NVR technique early postoperatively, along with more preserved motion of the posterior leaflet.
