Results of Surgical Repair
of Ostium Primum Atrial Septal Defect in Adult Patients The outcome of patients aged over 20 years having surgical repair of ostium primum defect was examined. Fifteen patients (10 males, five 5 females; mean age 31.4 ± 13.1 years) operated on between 1982 and 2000 were followed. All patients were examined physically and underwent chest radiography, ECG and echocardiography before and after surgery. Autologous pericardium was used to close the defect in 14 patients; a direct suture was used in one patient. Mitral valvuloplasty was performed in 12 cases, and tricuspid in eight. There were no hospital deaths among patients. Preoperatively, nine patients (60%) were in NYHA classes III and IV; at the end of follow up, 14 (93.3%) were in classes I and II. The mean preoperative cardiac volume index of 695 ± 216 ml/m2 was reduced after repair to 523 ± 108 ml/m2 (p <0.05). In one case, a residual intracardiac shunt was identified after surgery. The right ventricular dimension decreased from 5.0 ± 1.5 mm before surgery to 3.2 ± 0.6 mm after repair (p <0.001). In conclusion, patients aged over 20 years with ostium primum atrial septal defect benefit from surgical repair. |
