| Abstract | ||
| To assess the prevalence of Coronary artery anomalies (CAAs) and their subtypes in symptomatic, but stable adults with Multi-Detector CT Coronary Angiography (MDCT-CA). 50 patients were scheduled for multidetector computed tomography – coronary angiography (MDCT-CA) which enables detailed visualization of coronary arteries and heart anatomy, (clinically suspected patients with CAD & others with suspected congenital cardiac anomalies). Coming fasting, non-contrast cardiac CT scan for calcium score was carried, after intravenous injection of contrast material & ultra-thin cardiac scanning. Images were analyzed with MPR, cMPR, MIP & VR. The data of coronary artery anomalies were reported. Among the study patients, the incidence of congenital anomalies was 10.1%. Myocardial bridging was the most frequent reaching 38.5% among all anomalies. The 2nd most common coronary artery anomalies found at our study was Anomalous location of coronary ostium at improper sinus (ACOIS), being of about 15.4 % of total anomalies The prevalence of CAAs in our study was relatively similar or near to previous studies and the literature data. Thus, CTA is a non-invasive method and an excellent tool to diagnose and guide the management of CAAs. It enables excellent three-dimensional visualization and provides a clear delineation of the origin, course, relation to the adjacent structures, and termination compared with invasive coronary angiography. | ||
