Abstract

ABSTRACT: INTRODUCTION: Coronary artery fistulas are abnormal communications between a coronary artery and a cardiac chamber or a major vessel (vena cava, pulmonary vein, pulmonary artery). They are usually diagnosed by coronary arteriography. Clinical presentations are variable depending on the type of fistula, shunt volume, site of the shunt, and presence of other cardiac conditions. CASE PRESENTATION: This report describes a 46-year-old Greek female patient who was admitted to the hospital because of an acute coronary syndrome. She underwent coronary angiogram which showed a coronary artery fistula from the left anterior descending artery to the main pulmonary artery and severe coronary disease. The patient was referred for coronary artery bypass surgery and fistula closure operation. CONCLUSIONS: Coronary artery fistulas between left anterior descending artery and main pulmonary artery are very rare anomalies. This case report describes a patient with this anomaly combined with severe coronary disease, reviews the current literature and discusses the available options for treating this rare condition.
