Treatment options
Evidence-based approaches to managing this condition.
First-line treatments
Disease management and monitoring
Treatment options should be discussed with a qualified healthcare provider.
Serial Cardiac Imaging and Hemodynamic Assessment
Comprehensive monitoring including echocardiography and cardiac catheterization to assess defect hemodynamics, pulmonary pressures, and right heart function over time.
Surgical Atrial Septal Defect Closure
Complete surgical repair of the atrial septal defect through median sternotomy or minimally invasive approaches. The surgeon closes the defect with a pericardial or synthetic patch to restore normal anatomy.
Additional treatment options
Transcatheter Device Closure
Ambulatory catheter-based procedure using occlusion devices to close moderate-sized ASDs. Device selection is based on defect dimensions and surrounding tissue rims.
procedurePulmonary Hypertension Management
Pharmacologic therapy targeting pulmonary arterial hypertension when present with ASD. May include vasodilators and diuretics to reduce right heart strain and improve exercise tolerance.
medicationIntegrated Cardiac Wellness Program
Holistic approach combining nutrition counseling, stress management, breathing exercises, and patient education to support cardiovascular health and postoperative recovery.
