title: [Reconstruction of the left ventricle by circular endoventriculoplasty with septal exclusion].
abstract: Since 1984 the authors have developed a technical modification of left ventricular surgery after myocardial infarction. The principle is to reorganise the contractile muscle in a circumferential manner by excluding the fibrous akinetic parts of the interventricular septum. The operation consists of implanting sutures distally then resecting the exteriorized fibrous zones and finally mobilising the scarred endocardium in the zones inaccessible to resection (septum and the base of the anterior and posterior papillary muscles) up to the limits of the viable myocardium. A patch of septal endocardium or dacron lined with pericardium is sutured in the contractile muscular zone. One hundred and fifty patients have been operated for cardiac failure (37%), angina (40%) or arrhythmias (10%). One third of patients required intra-aortic balloon pumping in the preoperative period. Myocardial revascularisation was associated in 75% of cases. Surgery was performed as an emergency in 33 cases (25% mortality); in the remaining 117 cases the mortality was 5%. Postoperative control assessment (115 immediate postoperative and 60 one year controls) showed the left ventricular geometry to be almost normal and the global ejection fraction to have increased by an average of 17%. This technique of left ventricular remodelling with septal exclusion enables the surgeon to perform a more physiological repair in patients without cardiac failure and to extend the surgical indications in patients with cardiac failure.
