We report our experience of seven patients out of 27, who did not undergo surgery and were followed up for a mean period of 2.8 years. They were evaluated after a mean period of 2.2 months after infarction in our centre. The septal defects measured 9.8 mms on average and the mean left-to-right shunt ratio was 1.98: 1. The mean pulmonary artery, right atrial and left ventricular end diastolic pressures were 28.3 +/- 10.6, 4 +/- 3 and 15.8 +/- 4.8 mm Hg, respectively. Only three out of seven patients had LV aneurysm and all patients had single-vessel disease. Smaller defect size, minimal left-to-right shunt and preserved right ventricular function may be the factors responsible for long-term survival.Cardiology
