Anomalous Termination of Coronary Arteries
Coronary artery fistulas are anomalies of termination of the coronary arteries. Coronary artery fistulas are defined by a direct precapillary connection between a branch of a coronary artery and the lumen of a chamber of the heart or great vessel, typically pulmonary artery or inferior vena cava (IVC). These fistulas more commonly terminate in a lower pressure chamber of the heart such as the right ventricle or right atrium or a low-pressure great vessel such as the pulmonary artery or IVC. The coronary fistula to the right ventricle is most common (41%)  with termination into the right atrium accounting for 26% and pulmonary artery 17% .
