“…The prevalence of congenital coronary-pulmonary artery fistulas (CPAFs) varies between 0.17% and 0.68%, making them the least common type among all coronary artery fistulas, at 15-30% [1,2]. Most CPAFs are classified as anterior type, connecting the proximal part of the coronary arteries to the anterior wall of the pulmonary artery.…”

Coronary artery fistulas are abnormal connections between the coronary arteries and the heart or other surrounding vascular structures. Although they are usually congenital, they can also occur iatrogenically or due to trauma. They are usually asymptomatic, but they can cause serious and even fatal complications. These complications include myocardial infarction, embolism, thrombosis, arrhythmia, and rupture. In a 54-year-old woman admitted to the emergency department with an acute inferior myocardial infarction, a giant coronary-pulmonary artery fistula was detected on angiography. The fistula could not be closed percutaneously, and computed tomography angiography (CTA) revealed extensive aneurysms and diffuse calcifications. Large fistulas should be closed due to the risk of rupture. Small fistulas should be detected by CTA, and radiologists should be familiar with the imaging features.
