Abstract:
The concept of 'reconstructive cardiac surgery' using a stimulated autologous skeletal muscle has been investigated in this research. Our approach has been to investigate the substitution or reinforcement of a ventricular wall by a contractile tissue. The experiments have demonstrated the feasibility of this technique and the long-term adaptability and adequate electrophysiological properties of the Latissimus Dorsi flap transferred to a heterotopic position over the heart. Long-term biocompatible fatigue resistant muscle stimulation has become possible in experimental and clinical cases as a result of the development of specially designed electrodes and the use of a progressive sequential stimulation protocol to adapt the skeletal muscle to a cardiac support function. Autologous pericardium treated with glutaraldehyde was found to be a suitable material to close the ventricular cavity. Cardiomyoplasty with autologous skeletal muscle to restore ventricular contractility seems to be a valid alternative in addition to current methods of treatment for irreversible myocardial failure.
