Prevalence of Coronary Variants and Anomalies Detected on Computed Tomography Angiogram (CTA) Cardiac Among Patients
Journal Title: Journal of Health and Medical Sciences - Year 2019, Vol 2, Issue 1
Abstract
Objectives: To estimate the prevalence of coronary variants and anomalies detected on CTA cardiac patients. To determine demographics characteristics of the study respondents based on age, sex and coronary dominance. To determine any association between coronary variants and anomalies with: (i) total calcium score (ii) stress test results (iii) other concurrent congenital heart disease iv) significant / insignificant coronary artery occlusion (v) underlying myocardial infarction. Methods ¥ 83 CTA cardiac studies were included and analysed in this retrospective study. ¥ These data were retrieved from hospital’s archiving computer system (PACS) database. ¥ All of these CTA cardiac examinations were performed by using Siemens MDCT Scanner 64 slices. ¥ The identification of coronary variants and anomalies were performed by one trainee radiologist and subsequently verified by a cardiac radiologist. ¥ The data was analyzed by using Fisher’s Exact Test with significant value taken as p < 0.05. Results Detection of coronary variants and anomalies - 25.3%. • Ramus intermedius (RI) - 20.4% • Myocardial bridging of LAD (MB) - 3.6% • Left circumflex arising from right aortic cusp -1.2%. The patients who had CTA cardiac done were: ¥ within the range of 41 to 60 years old (54.2 %) ¥ majority were male patients (67.5%) Mostly are of right coronary dominance (86.7%).
