Abstract:
:Dynamic cardiomyoplasty is a new surgical procedure proposed for treatment of the failing heart. Clinically, the latissimus dorsi muscle is raised as a pedicled flap and wrapped around the heart. The skeletal muscle is transformed to produce a myocardium-like fatigue-resistant muscle. It is stimulated to contract in synchrony with the heart in hope of assisting the myocardial contraction. An R-wave synchronous pacemaker provides a pulse-train form of stimulation to simulate, for the skeletal muscle, the contractile characteristics of the myocardial syncytium. We have undertaken a critical review of the clinical results of dynamic cardiomyoplasty reported to date. Objective evidence of clinical improvement after dynamic cardiomyoplasty resulting from the contractile assistance of the myoplasty has been modest. Many of the beneficial results reported could be explained by concomitant procedures done, such as aneurysmectomy or coronary artery bypass grafting. Hemodynamic studies have failed to demonstrate consistent and convincing improvement as a result of the cardiomyoplasty stimulation. We have, however, identified an interesting subgroup of patients, in whom a striking hemodynamic response to cardiomyoplasty stimulation has been reported. These patients all possess large resting heart volumes characteristic of dilated cardiomyopathy. Thus, case selection may ultimately be one of the most important factors in determining the success of dynamic cardiomyoplasty for the treatment of heart failure.
