Coronary artery fistulas are rare and are most often diagnosed by echocardiography or by cine-angiocardiography. However, the computed tomography angiography (CTA) of coronary arteries has been gaining ground. The incidence of this disease is very low, with a more frequent occurrence of fistulas originating in the right coronary artery. There ...
