Intramyocardial skeletal muscle transplantation has been shown experimental
ly to improve heart function after infarction. We report success with this
procedure in a patient with severe ischaemic heart failure. Wa implanted au
tologous skeletal myoblasts into the postinfarction scar during coronary ar
tery bypass grafting of remote myocardial areas. 5 months later, there was
evidence of contraction and viability in the grafted scar on echocardiograp
hy and positron emission tomography. Although this result is encouraging, i
t requires validation by additional studies.
