Right coronary artery-right ventricle fistula with a rare giant thrombotic aneurysm: a case report and literature review.

ABSTRACT:

Background

Coronary artery fistula (CAF) is a rare vascular anomaly characterized by an abnormal shunt originating from a coronary artery and terminating at an atypical endpoint, typically involving dilated and tortuous vessels. The increased shunt flow can lead to a "coronary steal" phenomenon, resulting in angina pectoris. At present, the complications of CAF other than fistula steal need to be paid more attention, especially aneurysm rupture, thrombosis, and myocardial infarction. CAF may be accompanied by aneurysms, but it is seldomly reported that the aneurysm is giant with thrombosis and possibly relevant to myocardial infarction.

Case description

A 51-year-old female who presented stomachache, chest pain, and palpitation had been indicated as having right coronary art
