Key result
Coronary angiography in 7,858 patients revealed a 1.1% incidence of coronary artery anomalies, with right coronary artery dominance present in 70.99% of the cohort.
Why the study?
Coronary artery anomalies are found in 0.2% to 1.3% of angiograms, and the study aimed to describe congenital coronary artery anomalies, their variations, prevalence, and coronary artery dominance at a single center.
Observational (n=7,858)
No
The incidence of coronary artery anomalies in a Turkish center was 1.1%, consistent with other major studies, with a moderately high rate of circumflex dominance.

Adds regional CAA prevalence data consistent with prior reports; leaves open multicenter validation of dominance patterns.
BACKGROUND: Coronary artery anomalies (CAA) are found in 0.2% to 1.3% of coronary angiograms. The aim of the presented study was to describe congenital CAA and their variations, also identifying the prevalence of these anomalies and coronary artery dominance in our center.METHODS: A total of 7858 patients were included in the study retrospectively between August 2015 and March 2020. Patients undergoing coronary angiography (CAG) were reviewed by at least 2 independent and experienced observers. The Angelini’s CAA Classification method was used to classify patients. Coronary dominance was determined according to the artery from which the posterior desending artery originated.RESULTS: CAA was detected in 88 (1.1%) out of 7858 patients. Of these patients, 73 (82.9%) had anomalies of origination and course called group A, 7 (7.9%) had anomalies of intrinsic coronary arterial anatomy called group B, and 8 (9.1%) had anomalies of coronary termination called group C. Anomalous collateral vessels called group D were not detected. RCA dominance was N.=5579 (70.99%), Cx dominance was N.=1021 (12.99%), and codominancy was N.=1258 (16.01%).CONCLUSIONS: The incidence of CAA was 1.1% in total and is compatible with other major studies. According to the Angelini CAA clasification, group B anomalies are observed more frequently than other studies. Cx dominance is moderately high.
