Surgical treatment of mitral regurgitation employing mitral prosthetic ring

Abstract

Several surgical techniques for mitral regurgitation were progressively abondoned mainly because of the difficulty to achieve a regular and predictable result and high incidence of recurrent regurgitation. But the valve prosthesis still involve thrombotic problem and a persistent need of anticoagulation.
The recent and considerable progress in mitral valve surgery has been incentive for cardiac surgeon to improve our knowledge of the details of mitral valve and to perfect our surgical techniques to repair and reconstruct the mitral valve apparatus if possible. Progress in extracorporeal circulation and myocardial protection allows us to perform more sophisticated technique
The purpose of this paper is to state the Stanard principles and guidelines for reconstructive surgery of mitral regurgitation and its superiority in postoperative cardiac function rather than mitral valve replacement.
