Key result
Hemodynamically significant coronary artery anomalies were associated with a higher incidence of typical or atypical chest pain compared to other anomalies (44.9% vs. 17.3%, p < 0.001).

Coronary artery anomalies are present in 1.39% of patients undergoing CCTA, and a notable proportion of these patients present with typical or atypical chest pain even in the absence of obstructive coronary disease.
Purpose To determine the prevalence of coronary anomalies using coronary computed tomography angiography (CCTA) and to evaluate the relationship between coronary artery anomalies and chest pain. Materials and Methods A total of 12676 patients underwent CCTA scans at our institution between December 2006 and April 2013 using a 64-slice CT and a 128-slice dual-source CT. We determined the prevalence of coronary artery anomalies according to the classification system proposed by Greenberg. The presence or absence of chest pain with each coronary artery anomaly was also evaluated. Results Coronary anomalies were found in 176 patients (1.39%) at our institute. Anomalies of origination, course, and termination were detected in 118 (0.93%), 28 (0.22%), and 30 (0.24%) patients, respectively. After the exclusion of 32 patients with combined heart disease, typical (n = 16; 11.1%) or atypical (n = 28; 19.4%) chest pain was present in 44 (30.6%) of the 144 patients at the time of diagnosis. Conclusion The prevalence of coronary artery anomalies was 1.39% at our hospital. After the exclusion of patients with combined heart disease, 11.1% had typical chest pain at the time of diagnosis.

Yi et al. (2015) conducted an observational in Coronary artery anomalies (n=12,676). Hemodynamically significant coronary artery anomalies vs. Other coronary artery anomalies was evaluated on Incidence of typical or atypical chest pain (p=<0.001). Hemodynamically significant coronary artery anomalies were associated with a higher incidence of typical or atypical chest pain compared to other anomalies (44.9% vs. 17.3%, p < 0.001).
