Summary
Atrial septal aneurysm (ASA) is not rare in children. Type 2L ASAs require monitoring for potential atrial septal defect (ASD) development during follow-up.
Area of Science:
- Pediatric Cardiology
- Congenital Heart Disease
- Echocardiography
Background:
- Atrial septal aneurysm (ASA) is an uncommon condition in pediatric populations.
- Understanding the natural history and incidence of ASA in children is crucial for appropriate management.
Purpose of the Study:
- To determine the incidence of atrial septal aneurysm in a pediatric cohort.
- To evaluate the natural course and potential complications of pediatric ASA, including resolution and development of atrial septal defects (ASDs).
- To identify associated cardiac lesions commonly found with ASA.
Main Methods:
- Retrospective analysis of echocardiographic data to identify children with ASA.
- Classification of ASA into types (1R and 2L).
- Longitudinal follow-up of a subset of patients diagnosed with ASA.
Main Results:
- Atrial septal aneurysm was identified in 1% of the pediatric patients studied (30 patients).
- Type 1R ASA was observed in 16 patients, and type 2L ASA in 14 patients.
- During follow-up, ASA resolved in 4 patients; 3 patients with type 2L ASA developed an ASD. Patent foramen ovale (PFO) was the most frequent associated finding.
Conclusions:
- Atrial septal aneurysms are not as rare in children as previously thought.
- Type 2L ASAs warrant close monitoring due to the risk of developing an atrial septal defect.
- Routine echocardiographic follow-up is recommended for pediatric patients with ASA.
