Multislice CT coronary angiography has been accepted as a useful modality in evaluating coronary arteries in intermediate risk patients. It also helps to rule out congenital anomalies noninvasively in selected subjects to rule out the risk of sudden cardiac death and preoperatively before complex cardiac surgeries and hence awareness of coronary artery variations is essential in such conditions.The purpose of this study is to evaluate coronary artery variations in patients referred to our hospital for CT coronary angiography.
To study the congenital coronary artery variations.
METHODS AND MATERIALS
100 patients who had undergone CT coronary angiography on 128 slice CT scanner were evaluated retrospectively for coronary arterial variations.
A total of hundred patients were included in the study. Among them right dominance was 82%, left dominance was 12% and co-dominance was 6%. Ramus intermedius was noted in eight patients. One patient showed early bifurcation of LMCA. High origin of coronary artery was noted in another patient. Conus artery was arising directly from aorta in 20 patients.
128 slice CT coronary angiography provided accurate details of coronary arterial origin, course and variations. Multislice CT coronary angiography is a viable noninvasive modality for evaluating variations of coronary arteries.
