Functional mitral insufficiency is a disease of the entire mitral-papillary complex involving the left ventricle. Therefore, appropriate correction is necessary. In this regard, it is not surprising that most isolated techniques demonstrate unsatisfactory results. Indeed, these procedures influence only one component of functional mitral insufficiency, mainly mitral annulus. Correction of annular enlargement does not prevent left ventricular remodeling that results failure of most reconstructions. The authors report successful multicomponent mitral valve reconstruction involving the entire mitral-papillary complex in a patient with ischemic mitral insufficiency type IIIb. In 1 year after surgery, optimal hemodynamic parameters on the mitral valve and effective reverse left ventricular remodeling were observed.
