Eleven cases of ASD were experienced in subjects aged more than 50 years. The ages ranged from 50-68 years (mean: 57.1 years), and there were 6 males and 5 females. The preoperative NYHA class was I in three cases, II in six cases, and III in two cases. The pulmonary arterial pressure ranged from 20-46 mmHg (mean: 30.9 mmHg), the PP/PS 0.19-0.42 (mean: 0.25), the QP/QS 1.4-3.5 (mean: 2.3), and the left to right short circuit rate was 38-73% (mean: 58.6). A patch closure operation was performed in all cases except two. After operation, the NYHA class improved in all cases except one. The CTR decreased from 59.3 +/- 6.05% to 54.1 +/- 5.07, and the pulmonary arterial pressure from 30.3 +/- 6.65 mmHg to 21.4 +/- 5.04 mmHg (improving in all cases).
