Abstract

Background: Fetal echocardiography can diagnose neonatal atrial flutter, which can cause heart failure in newborns. Little is known about catheter ablation in this population.

Methods: Case report that aimed to review a successful ablation in a 20-day-old patient with refractory atrial flutter.

Results: This is the first report of a successful neonatal atrial flutter ablation without any early recurrence after the procedure.

Conclusions: Atrial flutter ablation performed on newborns is a reliable and long-lasting treatment option.

Keywords: ablation; atrial flutter; atrial septal defect.
