Detection of Coronary Artery Anomalies using 64 Slice MDCT Angiography
Journal Title: International Journal of Contemporary Medicine surgery and Radiology - Year 2017, Vol 2, Issue 3
Abstract
Introduction: Coronary artery anomalies are uncommon conditions of congenital origin with an incidence ranging from 0.17% in autopsy cases to 1.2% in cases undergoing conventional angiography. Coronary artery anomalies were evaluated by using catheter-based angiography and transesophageal echocardiography which are invasive methods. Multidetector row-computed tomography (MDCT) angiography is a recent non-invasive imaging technique and its importance is well established in the field of cardiac imaging. The purpose of this study was to evaluate the prevalence of coronary artery anomalies in patients using 64 slice multi detector CT coronary angiography. Materials and Methods: Retrospective study of 974 patients who underwent MDCT coronary angiography using 64 slice MDCT scanner for detection of coronary anomalies was done. Results: 14 (1.43%) patients had coronary anomalies with most commonly being the origin and course anomaly of the proximal coronary segments seen in 8(57%) patients. Left coronary anomalies (64%) were more common than the right coronary anomalies (36%). Conclusion: 64 slice ECG gated MDCT coronary angiography is an accurate non-invasive imaging modality which suitable to evaluate patients that have an anomalous coronary artery, especially when they have symptoms relating to anomalous vessels. Radiologists must be able to identify and characterize such anomalies and be aware of their clinical significance.
