Prevalence of congenital coronary artery anomalies as shown by multi-slice computed tomography coronary angiography: a single-centre study from Turkey

Abstract

ObjectiveCoronary artery anomaly (CAA) is a remarkable etiological factor for sudden cardiac death in young adults. The incidence of CAA is unknown, with most reliable data available based on postmortem/angiography investigations. This study aimed to assess the prevalence of different forms of coronary anomalies, and to investigate the relationships between demographic data and occurrence of CAA.MethodsA total of 2401 consecutive patients (1805 men; mean age, 56 ± 11.7 years), who were referred between January 2005 and December 2008 for noninvasive multi-slice computed tomography (MSCT) imaging, were retrospectively analysed.ResultsA total of 225 cases (191 men; mean age, 55.9 ± 12) of CAAs were identified (9.37%). Because 11 patients had multiple muscular bridges of the coronary arteries, 236 coronary artery anomalies were found in these 225 patients. Cases were classified into three groups: group 1, coronary anomalies of origin and distribution (n = 36, 1.5%); group 2, anomalies of intrinsic coronary arterial anatomy (n = 180, 7.49%); and group 3, anomalies of coronary termination (n = 9, 0.4%).ConclusionThe prevalence of CAA was 9.37% in our single-centre study, which is consistent with previous research. A minimally invasive tool, such as MSCT angiography, should be used to identify CAA.

Coronary Artery Anomalies by Multidetector Computed Tomography

“…Another study by Chaiyagool et al [7] showed almost double prevalence of coronary anomalies (61.6%). On the other side, the present study results were higher than those of Tongut et al [4] with prevalence of 10%.…”

“…The present study included 7 patients with abnormal origin of right coronary artery from left coronary sinus out of 630 patients (1.1%). Rao et al [5] reported those anomalies in 0.6% and Tongut et al, 2016 [4] reported them in 0.5% of the studied cases.…”

“…It has been a constant endeavor in coronary artery imaging to find a variety of non-invasive techniques that may successfully replace invasive conventional coronary angiography. Some of these techniques like computed tomography (CT) and magnetic resonance have shown promising results [4,5].…”

Most common anatomic anomalies of coronary arteries

“…Prevalence of anomalies of origin and of course was 1.02%, similar to what has been reported in other studies. 14,19 MBLAD, a 9.7% prevalence in our study, was considered a normal anatomic variant in other studies. When this anomaly is excluded, the prevalence of CA found in our study decreases to 1.27%, showing that, when such anomaly is considered, the result of the study can change.…”

“…Several studies only consider anomalies of origin and course, based on the Angelini et al classification 3 , or only disregard MBLAD as anomaly. [12][13][14][15][16][17][18][19] In addition, there are studies that use their own classification, [20][21][22][23] making it challenging to compare data unless one performs a re-analysis of the results using the same classification.…”
