Atrial septal defects (ASDs) can cause arrhythmias like atrial flutter. This rare case highlights an infant with an ASD who developed atrial flutter, successfully treated with cardioversion.
Area of Science:
- Pediatric Cardiology
- Electrophysiology
- Congenital Heart Disease
Background:
- Atrial septal defects (ASDs) can lead to supraventricular arrhythmias due to right atrial volume overload.
- Left-to-right shunting in ASDs alters atrial electrophysiology.
- Atrial flutter is an uncommon manifestation of ASD in infancy.
Purpose of the Study:
- To report an exceedingly rare case of atrial flutter in an infant with an ostium secundum ASD.
- To highlight the successful management of this condition.
Main Methods:
- Case report of an infant diagnosed with ostium secundum ASD.
- Documentation of the development of atrial flutter.
- Treatment with direct current cardioversion.
Main Results:
- The infant presented with atrial flutter secondary to an ostium secundum ASD.
- The atrial flutter was successfully treated with direct current cardioversion.
Conclusions:
- Atrial flutter, though rare, can occur in infants with ASD.
- Direct current cardioversion is an effective treatment for atrial flutter in this pediatric population.
