A study of coronary artery variants and anomalies observed at a tertiary care armed forces hospital using 64-slice MDCT

Abstract

Coronary CT angiography gives us a good understanding of the variations and anomalies of the anatomy of the coronary arteries. This can be of immense help to the clinician planning interventional procedures.

Coronary Artery Anomalies by Multidetector Computed Tomography

“…Six cases were reported with anomalous origin of left main coronary artery from right coronary sinus, representing a 0.9% of the involved patients. This nearly agreed with Rao et al [5].…”

“…The most common age group involved in this study was 50-<60 years. This is concordant with Rao et al [5] who stated the same most common age group. Female patients were more than male patients.…”

“…In the recent study, 320-slices CT machine was used, 217 coronary anomalies were detected among the 630 patients included in the study with their prevalence was 34.4%. The current results were comparable to the results of Rao et al [5] that used 64-slices CT machine and the coronary anomalies prevalence was 29.3%. Another study by Chaiyagool et al [7] showed almost double prevalence of coronary anomalies (61.6%).…”

“…The present study included 7 patients with abnormal origin of right coronary artery from left coronary sinus out of 630 patients (1.1%). Rao et al [5] reported those anomalies in 0.6% and Tongut et al, 2016 [4] reported them in 0.5% of the studied cases.…”

“…It has been a constant endeavor in coronary artery imaging to find a variety of non-invasive techniques that may successfully replace invasive conventional coronary angiography. Some of these techniques like computed tomography (CT) and magnetic resonance have shown promising results [4,5].…”
