Coronary artery fistula (CAF) in adults is a rare form of coronary artery anomalies. It is often diagnosed incidentally during coronary angiograms. The aim of this study was to evaluate clinical and angiographic characteristics of adult patients with CAF.
We retrospectively reviewed the database of 70850 patients who had undergone coronary angiography at 5 different invasive cardiology centers in the southeastern region of Turkey. Among them there were 56 patients with CAF (39 males and 17 females, mean age: 63.7±10.4 years). Demographic data and clinical evaluation, and cardiac catheterization reports were reviewed from medical records.
A total of 58 fistulas were detected in 56 patients; two patients (4%) had bilateral fistulas originating from both left coronary artery and right coronary artery. In our angiographic series, CAF prevalence was 0.079%. Dyspnea on exertion and / or angina pectoris was the most common symptoms (69%). There were 15 (29%) patients with concomitant obstructive coronary artery disease. Coronary artery fistulas were originated mainly from left anterior descending artery (n=30, 58%). Others were originating from right coronary artery (n=15, %29), circumflex artery (n=6, 11%), and right sinus of Valsalva (n=3, 6%). In four patients (n=4, 8%), there were multiple micro fistula drop into the left ventricle.
In our angiographic series, the prevalence of CAF was 0.079%. The most common site of origin was left anterior descending artery.
