 A special pacemaker is implanted to make the skeletal muscle contract.If cardiomyoplasty is successful and increased cardiac output is achieved, it usually acts as a bridging therapy, giving time for damaged myocardium to be treated in other ways, such as remodeling by cellular therapies.Cellular cardiomyoplasty is a method which augments myocardial function and cardiac output by directly growing new muscle cells in the damaged myocardium (heart muscle).
