BACKGROUND: Although, conventional surgical closure of atrial septal defect (ASD) provides excellent results with very low mortality and morbidity, it leaves the scar of incision and postoperative pain. Newer treatment modalities like minimal invasive surgery and percutaneous closure are being increasingly used nowadays where available. AIM: To compare the patient population, success, safety, and efficacy of transcatheter closure of ASD (Group A) with that of minimally invasive surgery (Port Access) (Group B). METHODS: In this retrospective non-randomized study, a record of a total of 640 patients with diagnosis of ASD secundum between May 1997 and October 2006 were reviewed. A total of 470 out of 640 patients were selected for transcatheter closure (Group A) while 170 patients were taken for surgical closure by minimally invasive port access surgery (Group B). The safety and efficacy of two groups was evaluated on the basis of morbidity and mortality, duration of intensive care unit (ICU) stay, total duration of hospital stay, post-procedural complications, residual sequel at time of discharge, and residual flow across the ASD. RESULTS: Success rate in two groups was 97.1% and 99.4%, respectively and had no statistically significant difference. Similarly major complication rate also had no difference in statistical significance (1.8% and 2.9% for Group A and B, respectively). Group B patients had longer hospital stay. A small but significant number of patients were not found suitable for device closure. This number is likely to decrease as experience with technique increases. Port access surgery is currently not possible in small children (femoral artery diameter 35 mm) due to difficulty in cannulation. CONCLUSION: Percutaneous device closure of ASD can be offered as a treatment option in suitable patients. Port access is minimally invasive and an equally safe and effective alternative choice in ASDs with deficient rim in patient with appropriate age and weight.
