Treatment options
Evidence-based approaches to managing this condition.
First-line treatments
Device Closure with Amplatzer or Similar Occluder
Percutaneous approach using a self-expanding closure device positioned across the ASD under fluoroscopic and echocardiographic guidance. Ideal for secundum-type defects with adequate rims.
Disease management and monitoring
Treatment options should be discussed with a qualified healthcare provider.
Patch Closure via Cardiopulmonary Bypass
Open heart surgical repair using autologous pericardium or synthetic patch material. Performed under general anesthesia with cardiopulmonary bypass support.
Additional treatment options
Anticoagulation and Antiplatelet Therapy
Medical therapy to prevent thromboembolic complications, particularly in patients with atrial arrhythmias or those with residual shunts following closure procedures.
medicationLong-Term Follow-Up and Surveillance
Lifetime cardiology follow-up including periodic echocardiograms, ECG monitoring, and exercise tolerance assessment to detect complications such as arrhythmias, residual leaks, or device-related issues.
monitoringCardiac Rehabilitation and Exercise Conditioning
Phase II and III cardiac rehabilitation providing supervised exercise training, education on heart-healthy living, and psychosocial support for patients recovering from ASD repair.
