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
