Category: Clinical Sciences

Abstract:

Background : Anomalies of the coronary arteries are a rare may be found incidentally in 0.3%–1% of healthy individuals and might be the cause of myocardial ischemia and sudden death. In this article we describe a pictorial anatomy of the coronary arteries of the heart and some of the anomalies with illustrations and CT- images. Cardiovascular computed tomography (CT) has emerged as the standard for identification and characterization of coronary artery anomalies.

Materials and methods: We present an account of incidentally diagnosed coronary artery variants and anomalies culled from a CT data of 1600 patients who underwent 64-slice CT angiography (CTA) (Siemens Sensation 64 CT Scanner) because of known or suspected coronary artery disease were retrospectively reviewed by two radiologists experienced in cardiovascular radiology from 2006 till 2012 at our Institute.

Results : Coronary artery anomalies (CAA) are uncommon congenital variations in coronary anatomy, occurring in 2% of the general population ( as per our study)

Conclusion :. Familiarity with the CT appearances of various coronary artery anomalies and an understanding of the clinical significance of these anomalies are essential in making a correct diagnosis and planning patient treatment.
