Surgical Management of Congenital Bilateral Multiple Atrial Aneurysms.

Abstract

Congenital atrial aneurysms are a rare malformation, often associated with supraventricular arrhythmias. Here, we present the case of a child with biatrial aneurysms and a type 2 atrioseptal defect. Directly after birth the girl became symptomatic with incessant ectopic atrial tachyarrhythmia. On echocardiography, multiple biatrial aneurysms and septations were observed. The diagnosis was confirmed with computed tomography. After 7 months of antiarrhythmic therapy, the child underwent surgical intervention by aneurysm resection, atrioseptal defect closure, and ablation. Since then the patient has been in stable sinus rhythm.
