[Immediate Results of Mitral Valve Surgery in Asymptomatic Patients With Severe Mitral Regurgitation Due to Degenerative Mitral Valve Disease].

Degenerative mitral valve disease nowadays is the most common cause of mitral insufficiency in developed countries and is associated with high morbidity and mortality. In the last decades repairing the mitral valve has become the operation of choice for treatment of the mitral valve prolapse, enabling to improve the geometry and function of the left ventricle and long-term survival. Nevertheless, the problem of choice of method of management of severe mitral regurgitation in asymptomatic patients with degenerative mitral valve disease remains unsolved. In this article we present immediate results of a prospective comparative study of mitral valve surgery in asymptomatic and symptomatic patients in dependence on NYHA class of heart failure.
