Long Term Results of Surgical and Percutaneous Double Orefices Mitral Repair in Patient With p2 Prolapse Causing Degenerative Mitral Regurgitation

April 28, 2023 updated by: Michele De Bonis

Mitral regurgitation is a pathology affecting the left atrioventricular valve that causes a volumetric and pressure overload in the left chambers due to the loss of unidirectionality normally guaranteed by the cardiac valve system. The gold standard for severe mitral regurgitation is currently mitral valve plastic surgery.

Edge to edge, on the other hand, allows shorter CEC and aortic clamping times and does not require significant surgical experience in the field of mitral valve repair, therefore edge to edge could be an excellent strategy in patients suffering from mitral regurgitation caused by P2 prolapse when quadrangular resection cannot be performed.

The main objective of the present study is to examine the medium to long-term outcomes (in terms of survival and plastic outcomes) of patients undergoing central edge-to-edge to treat posterior flap pathology (P2).
