Abstract

 

Coronary artery fistulas are rare anomalies that occur as an incidental finding in 0.1% to 0.2% of coronary angiograms.  In this case report we present a 64-year-old symptomatic patient with right coronary artery (RCA)-main pulmonary artery (MPA) fistula.

Coronary angiography showed stenosis of left anterior descending coronary artery (LAD) and circumflex artery (Cx).  There was fistulization of RCA to MPA as well.  Following coronary artery bypass grafting (CABG), both ends of the fistula were closed with epicardiac clips in the same operation.

During the postoperative course, no complication was observed.  In the follow-ups, the patient did not complain of his preoperative symptoms and no additional problem was observed.

Coronary artery fistulas are uncommon congenital anomalies that may cause serious clinical symptoms, even sudden death.  Early surgical treatment is a safe and necessary approach.
