Abstract
The principle of cardiomyoplasty is longterm electrostimulation of alatissimus dorsi muscle LDM wrapped around the failing heartTechnically this procedure consists of placing the left LDM flap aroundthe heart via a window created by partial resection of the 2nd or 3rd riband subsequent muscle electrostimulation in synchrony with ventricularsystole The aim of cardiomyoplasty is to support ventricular function inischemic or dilated cardiomyopathies or to partially replace theventricular myocardium after large aneurysm or tumor resections Ourclinical experience at Broussais Hospital involves 44 patients Thefunctional class and quality of life improved after cardiomyoplastyImprovement of the ventricular performance and limitation of cardiacdilatation were demonstrated over the longterm The actuarial survival at6 years was 71 Risk factors influencing perioperative mortality were age 65 years associated surgical procedures pulmonary vascularhypertension and patients hemodynamically unstable or on inotropic drugsupport Preoperative risk factors influencing the longterm mortalitywere permanent NYHA functional class 4 cardiothoracic ratio 060 LVejection fraction 15 biventricular heart failure and atrialfibrillation Cardiomyoplasty does not preclude the use of futureorthotopic heart transplantation
