Dynamic cardiomyoplasty: indication, surgical technique, and results

Abstract

The efficacy of dynamic cardiomyoplasty is still controversial. To date more than 400 patients have been operated worldwide. In recent years the indication and the surgical technique have become more uniform, which makes results from different centers eligible for comparison. We performed cardiomyoplasty exclusively in patients with contraindications for heart transplantation, such as chronic and recurrent infections or severe, irreversible sequelae of diabetes. Between August 1990 and October 1994, 8 isolated cardiomyoplasty procedures were performed in patients with cardiomyopathy (EF 14-32%, all in NYHA III). One patient died 2 months after surgery. Reported are the results of 7 patients after a mean follow-up of 41.1 +/- 14.1 months. Considerable symptomatic improvement was found in 6 or 7 patients, 3 of whom went back to work. One patient with severe pulmonary hypertension exhibited no improvement. In the others NYHA class improved by at least one. Echocardiography showed an increase in fractional shortening in all patients. LVEF increased from 21.2 +/- 5.2% to 38.1 +/- 15.9% (n = 7, p < 0.015) at 1 year, to 36.6 +/- 17.6% (n = 6, p < 0.05) at two years, and to 36.4 +/- 18.9% (n = 5, NS) at three years.
