Abstract
Background
Atrial flutter not responding to medications could be secondary to structural malformations of heart.
Case characteristics
A 5-year-old child with resistant arrhythmia, with onset in neonatal period.
Outcome
Multiple right atrial diverticuli were detected on CT angiography and cardiac catheterization. Patient reverted to sinus rhythm following surgical excision of diverticuli.
Message
In cases of intractable supraventricular tachycardia, structural anomalies of atrium should be suspected.
