THE INCIDENCE AND PATTERN OF ANOMALOUS CORONARIES IN JORDANIAN POPULATION

Abstract

Objective:To determine the frequency and pattern of coronary anomalies on angiography in
the Jordanian population.Methods: This is a retrospective study conducted at Queen Alia
Heart Institute in Amman-Jordan during the period 2007 to 2010. A total number of 2950
adult patients who had coronary angiography which were reviewed looking for the presence
of anomalous coronary arteries and their pattern of occurrence.Results: The total number of
angiograms studied was 2950, with 38 cases showed coronary anomalies (1.3%).The
commonest anomaly was circumflex from right sinus or right coronary artery (29.0%).
Myocardial bridging reported a high incidence of occurrence (23.7%). The distribution of
other coronary anomalies was found to be almost the same to what was reported in the
literature. The incidence of coronary artery disease in the anomalous arteries was low
(28.9%).
Conclusion: The prevalence of coronary anomalies in Jordanian population is lower than the
ratios mentioned in the literature but has almost the same pattern,with low risk for developing
atherosclerosis in the anomalous vessel.They are usually benign; however, angiographic
recognition of these vessels is clinically significant especially in patients undergoing coronary
angioplasty or heart surgery.
