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.
Regular Echocardiographic Surveillance
For small ASDs that may close spontaneously, regular echocardiograms are performed to monitor the defect size, cardiac function, and any progression of symptoms over time.
Open Heart Surgical Repair
Primary surgical closure of the atrial septal defect using a patch or direct suturing technique during cardiopulmonary bypass. This approach is recommended for larger defects or those not suitable for catheter-based closure.
Additional treatment options
Percutaneous Catheter-Based Closure
Minimally invasive closure device placement via cardiac catheterization. A closure device is deployed across the defect under imaging guidance, allowing tissue to grow over the device.
procedureSymptom Management Pharmacotherapy
Medical management of associated symptoms such as heart failure, arrhythmias, or pulmonary hypertension using appropriate cardiovascular medications as prescribed by a cardiologist.
medicationActivity Modification and Cardiac Rehabilitation
Structured exercise program and activity guidance tailored to cardiac capacity. Includes aerobic conditioning, strength training, and education on activity pacing and symptom monitoring.
