Cardiomyoplasty

Cardiomyoplasty is a surgical procedure that involves the use of skeletal muscle to assist the heart in its pumping action. This procedure is typically used in cases where the heart has been weakened due to conditions such as heart failure or cardiomyopathy.

Procedure

The procedure involves wrapping a portion of the latissimus dorsi muscle around the heart. This muscle is then stimulated to contract in synchrony with the heart, thereby assisting the heart's own contractions. The muscle is typically stimulated using a pacemaker, which is implanted during the procedure.

Indications

Cardiomyoplasty is typically indicated for patients with severe heart failure who are not candidates for heart transplantation. It may also be used in patients with dilated cardiomyopathy who have not responded to medical therapy.

Risks and Complications

As with any surgical procedure, cardiomyoplasty carries certain risks. These may include infection, bleeding, and complications related to the use of anesthesia. In addition, there is a risk that the latissimus dorsi muscle may not adequately assist the heart, leading to continued heart failure.

Prognosis

The prognosis following cardiomyoplasty varies depending on the patient's overall health and the severity of their heart failure. Some studies have shown improved survival rates and quality of life following the procedure, while others have shown no significant benefit.
