AbstractBackground: Many believe that dyskinesia is the only predictor of favorable surgical outcome after large myocardial infarction and that akinetic scars do not recover well in patients with globally depressed ventricular function. Methods: This study evaluates clinical and hemodynamic results of endoventricular circular patch plasty in patients with either large akinetic scar (n = 51) or large dyskinetic scar (n = 49) and depressed left ventricular function (ejection fraction <30%). Groups were comparable for symptoms, indication for operation, and delay from myocardial infarction. Heart failure was a major indication for operation in both groups. Coronary grafting was performed in 98% of patients: 10 had mitral valve repair or repla...
