Summary
Early transcatheter closure of atrial septal defects in teenagers leads to better heart function and fewer arrhythmias compared to adult closure. This suggests timely intervention improves long-term cardiac outcomes.
Area of Science:
- Cardiology
- Pediatric Cardiology
- Interventional Cardiology
Background:
- Secundum atrial septal defects (ASD) are congenital heart conditions.
- Transcatheter closure is a common treatment for ASD.
- Long-term outcomes comparing teenage versus adult closure are not well-established.
Purpose of the Study:
- To compare the long-term outcomes of percutaneous transcatheter closure of secundum ASD in teenagers versus adults.
- To assess differences in electrocardiographic and echocardiographic parameters between the two groups.
Main Methods:
- 100 patients with secundum ASD underwent transcatheter closure 2-5 years prior.
- Patients were divided into two groups: teenage (13-19 years) and adult (>30 years) closure.
- Comparison included resting ECG, 24-h Holter ECG, and transthoracic echocardiography.
Main Results:
- Adults showed higher rates of right bundle branch block (69% vs 45%) and arrhythmias like premature atrial contractions (20% vs 6%) and atrial fibrillation (12% vs <1%).
- Adults had significantly larger right ventricular diameter, right atrial area, left atrial volume, and more left ventricular diastolic dysfunction.
- Teenage group exhibited better right ventricular systolic function.
Conclusions:
- Early transcatheter closure of secundum ASD during teenage years results in superior right ventricular systolic function and size.
- Teenage closure is associated with a lower incidence of atrial arrhythmias compared to adult closure.
