A surgical method of reconstructing damaged cardiac muscle via latissimus dorsi autograft. The latissimus dorsi is dissected from its origin and insertion while maintaining the neurovascular bundle intact. The dissected muscle flap is passed into the thorax through a rib resection in the corresponding axilla. After appropriate midsternotomy, cardiopulmonary bypass, etc., the muscle flap and its preserved neurovascular bundle may be used as graft muscle in the reconstruction of cardiac muscle. The latissimus dorsi autograft minimizes or eliminates the problems of histoincompatibility associated with cardiac transplantation. A subsequent protocol of suitable pacing of the autograft enables it to contribute to the overall cardiac function, and the structural presence of the grafted muscle tissue permits cardiac muscle repair without distorting the shape of the heart in the area(s) of excised cardiac muscle.
