A rare cause of cardiac syncope: aorto-right atrial connection.

Syncope in children is commonly benign, yet rare cardiovascular anomalies may be causative. We present a child with recurrent syncope, ultimately diagnosed with an aorto-right atrial connection. Transcatheter closure was successfully performed with an Amplatzer Duct Occluder II. This case emphasizes considering aorto-atrial connections in pediatric syncope with continuous murmurs and highlights the efficacy of percutaneous closure.
