Transcatheter closure of aorto-right atrial fistula.

ABSTRACT:

Background

Aorto-right atrial fistulas are rare complications of cardiac surgery that can result in heart failure due to continuous left-to-right shunting. In patients with recent sternotomy, reoperation carries significant risk, making transcatheter closure a compelling alternative.

Case summary

A 64-year-old man with a history of diabetes, cerebrovascular disease, and recent coronary artery bypass grafting complicated by ascending aortic dissection and repair presented with progressive dyspnoea. Prior to transfer, echocardiography suggested a cardiovascular fistula. On admission, multimodality imaging-including transthoracic and transoesophageal echocardiography and computed tomography-confirmed an aorto-right atrial fistula with elevated pulmonary artery pressures.
