Dynamic cardiomyoplasty for treatment of idiopathic dilatative cardiomyopathy in a dog.

Abstract

In a dog with advanced dilatative cardiomyopathy, dynamic cardiomyoplasty resulted in improvement in clinical status and systolic function. Dynamic cardiomyoplasty involved surgical isolation of the right latissimus dorsi muscle on its neurovascular pedicle, transposition of the muscle into the thoracic cavity, wrapping the ventricles with the muscle, and implantation of a myostimulator for cardiosynchronous stimulation of the muscle. After a 2-week period, the latissimus muscle underwent a 50-day period of progressive burst stimulation to transform the muscle to a fatigue resistant phenotype. Thereafter, the muscle received cardiosynchronous stimulation at a 3:1 R-wave-to-burst ratio. This procedure may offer hope for long-term treatment of dilatative cardiomyopathy in dogs.
