Abstract

Background and purpose: Coronary arteries anomalies (CAA) are generally rare but more common to co-exist with congenital cardiac anomalies. These include several congenital conditions either origin, course, or termination. This study aims to emphasize that the accurate evaluation of CAA on cardiac computed tomography angiography (CTA) is a must prior to proper surgical intervention in congenital heart diseases (CHD) to prevent unnecessary procedures or vascular injury of these vital arteries. Methods: Cardiac CTA scans for patients with suspected cardiac anomalies or diseases were retrospectively reviewed by radiologist for the presence of CAA between February 2020 and March 2023. CAA were found in 162 patients of the cardiac CTA reports done for CHD. They were categorized according to anomalies of origin, course, location of sinuses, or termination. Results: A total of (900) reports were scanned for CAA. After exclusion of unfit and repeated reports, CAA were detected in 162 patients (103, 63.6% males). Three (1.9%) patients had anomalous origin of left coronary artery from pulmonary artery (ALCAPA), while (27, 16.6%) had Common origin of left coronary artery (LCA) or its branches from right coronary ostium, (16, 9.8%) had origin of LCA or its branch from opposite or non-coronary sinus (NCS). Thirteen (8%) patients had ectasia of the right coronary artery (RCA) and (1, 0.6%) had both ectasia and aneurysm. Six (3.7%) patients had RCA fistula. Conclusions: Meticulous evaluation for presence of CAA on cardiac CTA done for assessment of CHD is mandatory to avoid surgical and long-term morbidity and mortality.
