INTRODUCTION :
Functional mitral regurgitation is a frequent complication of dilated cardiomyopathies and can seriously alter the vital prognosis of patients with heart failure.
The better understanding of the pathophysiological mechanisms of mitral regurgitation; a consequence of ventricular remodeling, and the new surgical treatments resulting from it allow excellent correction of mitral insufficiency as well as primary ventricular remodeling by plasty of the base of the left ventricle, and secondary by the reduction of the parietal tension
