Effects of the Surgical Techniques on Long-Term Results in Patients with Degenerative Mitral Valve Bi-Leaflet Prolapse

MVr in DMVBLP patients achieved a better preservation of left ventricular systolic indices than MVR, and guaranteed better shortand long-term survivals. When MVr is not feasible, it is recommended that subvalvular preservation be performed during MVR, in order to reduce the risk of early and late mortality and to improve left ventricular function.
