Background: The aim of our study is to determine the incidence of single coronary artery (SCA). SCA is a rarely seen coronary anomaly in which the right coronary artery and the left main coronary artery arise from single aortic sinus. Although SCA has a benign course in most cases and its clinical significance is unknown, in some autopsy studies it was shown to be related to sudden cardiac death. Materials and methods: SCA patients detected among 215,140 coronary angiographies (CAG) performed between 1998 and 2013 in SANKO Hospital were included in our study. The classification of CAG was made according to the two different classifications defined by Smith and Lipton and colleagues. Results: A total number of 215,140 patients who underwent routine CAG were included in the study, and SCA was detected in 67 (0.031%) patients. There were 6 (9%) type R-I, 23 (34%) type R-II, 10 (15%) type R-III, 16 (24%) type L-I and 12 (18%) type L-II patients according to the angiographic classification. Conclusions: SCA is rarely seen during routine cardiac catheterisation and its incidence is 0.014–0.066% in angiographic series. In our study, the incidence was shown to be similar to the previous studies. (Folia Morphol 2014; 73, 4: 469–474)

Background: The prevalence of coronary artery anomalies (CAA) are reported between 0.6–1.3% in the literature. CAA are usually asymptomatic incidental findings, but they may deteriorate coronary circulation, cause symptoms and lead to sudden cardiac death; especially in young athletes. Since interventional procedures are increasing rapidly for treatment of coronary artery disease (CAD) in the modern era, comprehensive understanding of CAA is becoming progressively critical element in dealing with CAD. Materials and methods: We reviewed the database of the Cardiac Catheterisation Laboratory of Sani Konukoglu University Hospital in Gaziantep, Turkey. All patients who were subjected to coronary angiography from 1998 to 2006 were included. Results: Among 53,655 coronary angiographies performed, CAA were found in 653 patients (incidence of 1.21%); 590 (90.3%) patients had anomalies of origin and distribution and 63 (11.7%) had coronary fistulae. Separate origins of left anterior descending (LAD) and left circumflex (LCX) coronary artery from the left sinus of Valsalva was the most common anomaly (64.1%). Coronary arteries branching from anomalous aortic origin was the second most common anomaly (16.5%). Right coronary artery (RCA) originating from left sinus of Valsalva or left main coronary artery (LMCA) was observed in 55 (8.4%) patients, LCX arising from RCA or right sinus of Valsalva (RSV) was seen in 52 (7.9%) patients and LMCA or LAD originating from RSV was seen in 14 (0.2%) patients. There were 16 (2.45%) patients with single coronary artery and 1 (0.15%) patient with LMCA originating from pulmonary artery. Conclusions: The incidence and the pattern of CAA in our patient population were similar with previous studies. Angiographic recognition of these vessels is important because of their clinical significance and importance in patients undergoing coronary angioplasty or cardiac surgery.
