ABSTRACT
Coronary anomalies are not rare [about 1'% of the general population] and may be associated with sudden dealth and ischemia and may cause difficulties in coronary interventions and errors in bypass surgery. The aim of this study is to demonstrate their incidence in the Sudanese patients and give a review on their classifications and clinical relevance- A retrospective study of 270 patients who had coronary angiography at Ahmed Gasim cardiac center from April, 2004 to August, 2005 Our study showed a rather higher rate of coronary anomalies [3%] but the pattern was not greatly different from the figures in the literature. Anomalies of origin were the most common [which may give difficulties in coronary interventions]. Potentially morbid anomaly with either the left anterior Ascending artery [LAD] or the left main coronary artery [LMCA] originating from the right coronary sinus was seen in 3 patients [1, 1%]. This study demonstrated that coronary anomalies are not rare in our patients and potentially serious anomaly may exist
