Coronary Artery to Pulmonary Artery Fistula: A Congenital Rare Defect in Adult. How was it Managed?-A Case Report

Abstract

Coronary artery fistula (CAF) is a rare anatomic abnormality of the coronary arteries that results from abnormal communication between a coronary artery and either the chambers of the heart or the great vessels that bypass the myocardial capillary bed. It is usually congenital, but it can be acquired. Both male and females are affected. Clinical presentation may be asymptomatic or symptomatic and it depends on the type of fistula, size of the fistula, site of the shunt and severity of the shunt. Coronary angiography is the gold standard for the diagnosis of coronary artery fistula. Surgery is indicated when a patient is clinically symptomatic, even in asymptomatic patients those are at risk for future complications.
