title: [Chronic mitral insufficiency secondary to coronary arteriosclerotic cardiopathy. Results of surgical treatment in 16 cases].
abstract: Our experience with 16 patients operated upon for chronic mitral insufficiency secondary to coronary artery disease is reported. The patients ranged from 40 to 65 years in age; all were in class III or IV of the N.Y.H.A. classification (10 in class IV), 3 were resuscitated from ventricular fibrillation and 11 had a cardiac index less than 2.2 1/min/m2. 15 patients had replacement of the mitral valve with a mechanical or biological prosthesis and 1 had mitral valve repair. 11 of the 16 patients also underwent aorocoronary bypass procedures. There were 2 deaths within the first 30 days following the operation (operative mortality 12.5%) and 6 more deaths during the follow-up period. 6 patients died of heart failure, correlated in 3 cases with extremely severe impairment of left ventricular function (wall motion abnormalities in all segments of the ventriculographic perimeter). Death was sudden in 2 cases. In the 8 surviving patients the clinical result is good. Preoperative factors affecting post-operative prognosis are investigated and guidelines of the indications for the surgical treatment are discussed.
