Introduction: Successful closure of atrial septal defect (ASD) improves patients' functional class and exercise capacity. In this study we evaluate the safety and feasibility of percutaneous device closure of ASDs.
Methods: Two hundred fifty six patients with significant ASD according to our criteria were enrolled. The patients were treated using nitinol wire mesh transcatheter devices. Complications were followed for a median of 2.5 years.
Results: Success rate was 98.4% with 3 unsuccessful cases and a mean hospital stay of 1.007 ± 0.0004 days. Complication rate was 7.42%. Size of the right ventricle (RV) annulus was significantly decreased 24 hours after intervention (P = 0.005).
Conclusion: The present report demonstrates that transcatheter closure of ASD is safe and effective.
