Percutaneous closure of congenital aortic-to-right atrial fistula.

Transthoracic and transesophageal imaging of a 30-year-old patient who presented with palpitations and shortness of breath revealed flow from the aorta to the right atrium. An aortic-right atrial fistula, which is a rare anomaly, was evaluated. As there was no acquired cause, it was considered a congenital defect. Due to the patient's being symptomatic, a percutaneous closure was performed with the Amplatzer Duct Occluder II device.
