Bottom Line: The anomalous location of coronary ostium on the aortic root was observed in 1 case (0.06%).An anomalous collateral vessel was observed in 1 case (0.06%).The prevalence of coronary artery anomalies in Korean men was 1.14%.

ABSTRACT

Background and objectives: It has been demonstrated that the anomalous origin of coronary arteries (AOCA) are generally asymptomatic and rare diseases. However, some cases can cause severe life threatening events. To detect these anomalies, coronary angiographies and autopsies were used to detect coronary artery anomalies, but these procedures have limitations because of their invasiveness. The new device, Multidetector Computed Tomography (MDCT), now replaces the method of choice for detecting coronary anomalies. The prevalence of these anomalies in Korea has not been studied yet. This present analysis attempted to determine the prevalence of AOCA in Korean men by MDCT.

Subjects and methods: 1582 Korean male police officers underwent coronary MDCT for their health screening voluntarily. After reconstruction of CT images, we could confirm coronary artery anomalies.

Results: The prevalence of AOCA in Korean men was 1.14% (18 out of 1582 cases). The most common abnormality (11 cases, 0.70%) was the origin of the coronary artery. Anomalies of the coronary artery end point were observed in 5 cases (0.32%). The anomalous location of coronary ostium on the aortic root was observed in 1 case (0.06%). An anomalous collateral vessel was observed in 1 case (0.06%).

Conclusion: The prevalence of coronary artery anomalies in Korean men was 1.14%. Coronary CT is a safe and noninvasive modality for detecting coronary anomalies.

Anomalous origin of right coronary artery. A: volume-rendered CT image shows RCA (white arrow) and LCA (black arrow) arising from the left coronary sinus. RCA with a course between Ao and PA. B: CT image shows high interarterial course. An anomalous RCA ostium (black arrow) from the left coronary sinus is located between the Ao and the RVOT above the pulmonary valve (white arrow). C: CT image shows low interarterial course. An anomalous RCA ostium (black arrow) from the left coronary sinus is located between the Ao and the RVOT below the pulmonary valve (white arrow). RCA: right coronary artery, LCA: left main coronary artery, Ao: aorta, PA: pulmonary artery, RVOT: right ventricular outflow tract.

Figure 1: Anomalous origin of right coronary artery. A: volume-rendered CT image shows RCA (white arrow) and LCA (black arrow) arising from the left coronary sinus. RCA with a course between Ao and PA. B: CT image shows high interarterial course. An anomalous RCA ostium (black arrow) from the left coronary sinus is located between the Ao and the RVOT above the pulmonary valve (white arrow). C: CT image shows low interarterial course. An anomalous RCA ostium (black arrow) from the left coronary sinus is located between the Ao and the RVOT below the pulmonary valve (white arrow). RCA: right coronary artery, LCA: left main coronary artery, Ao: aorta, PA: pulmonary artery, RVOT: right ventricular outflow tract.

Mentions: The overall incidence of coronary artery anomalies was 1.14% (18 out of 1582 participants). The most common anomaly was an abnormal origin of the coronary ostium arising from an opposite or non-coronary sinus (n=11, 0.70%), and 7 out of 11 cases of abnormal origin were in the right coronary artery (RCA) arising from the left coronary sinus (0.44%) (Fig. 1). All of them were of an interarterial type, which the RCA runs between the pulmonary artery and the aorta. The second most common anomaly was fistulas from RCA, left coronary artery, or infundibular artery to the main pulmonary trunk and appeared in 5 cases (0.32%) (Fig. 2). An anomalous location of coronary ostium on the aortic root was detected in only one person (0.06%) (Fig. 3). An anomalous collateral vessel which is connecting proximal RCA and proximal LAD, was observed in 1 case (0.06%). The classification of coronary anomalies and their prevalence was presented according to anatomical criteria of origin, course, intrinsic anatomy, termination, and collateral vessels (Table 2).
