Abstract BACKGROUND: Although the prevalence of coronary artery anomalies varies in different series, the precise population frequency is unknown. MATERIALS AND METHODS: The medical records of all patients who underwent coronary angiography between January 2002 and August 2012 were retrieved, and 238 cases with coronary anomalies were evaluated. Unlike other studies, we compared several angiographic parameters (fluoroscopy time, number of images, and catheters used) in addition to frequency and sex data. RESULTS: The angiographic frequency of coronary artery anomalies was 0.94\%. The most common coronary anomaly was a left anterior descending-circumflex artery originating from separate ostia (0.29\%). The second most common anomaly was a right coronary artery (RCA) originating from the left sinus of Valsalva (sV) (0.23\%). Overall, coronary artery anomalies (1.28 vs. 0.80\%; P<0.001) and a left anterior descending-circumflex artery originating from separate ostia (41.3 vs. 25.3\%, P=0.010) were more frequent in women than in men. The percentage of patients requiring more than two catheters during the procedure was significantly higher for an RCA originating from the left sV (45.7 vs. 16.7\%, P<0.001) and in hypertensive patients (85.7 vs. 70.8\%, P=0.015). On comparing the three most common coronary anomalies, an anomalous RCA originating from the left sV had a significantly higher value for at least one angiographic parameter. CONCLUSION: An anomalous RCA originating from the left sV is the most difficult type of anomaly to perform the ostial coronary cannulation during procedure. The results of this study may lead to the development of more suitable diagnostic catheters for an anomalous RCA originating from the left sV.
