Dynamic cardiomyoplasty: impact of effective pacing.

Dynamic cardiomyoplasty, in which the transposed latissimus dorsi muscle is wrapped around the heart and then electrically stimulated to augment systolic dysfunction, is an alternative surgical treatment for severe cardiomyopathies. Critical to success of this operation is to provide the wrapped skeletal muscle with more fatigue-resistant structure through repetitive electrical stimulation. A cardiostimulating device is important in this regard to perform synchronised contraction contributing to symptomatic improvement. Here in, we present a case with dynamic cardiomyoplasty improving following renewal of impaired myostimulator device.
