Value of 64 MSCT for evaluation of coronary artery anomalies and prognosis

Objective: To assess the value of 64 multislice spiral CT for evaluation of the origin of coronary artery anomalies and prognosis. Methods: 1211 patients undergone coronary artery CT angiography(CTA) were reviewed for this study. Results: In consecutive 1211 patients, 64 MSCT identified 18 cases(2.17%) with an anomalous origin of the coronary artery, including anomalous origin of the right coronary artery from left coronary sinus(n=5), anomalous high origin of the right coronary artery(n=1), separate origin of CB from right sinus(n=4), anomalous origin of the left coronary artery from right coronary sinus(n=3), left circumflex coronary artery from right sinus(n=1), separate origin of left circumflex coronary artery and left anterior descending arteries from left coronary sinus(n=5). Three coronary arteries in 8 patients with anomalous origin showed mild stenosis. Conclusion: Noninvasive 64 MSCT can detect the anomalous origin of the coronary artery with high resolusion, and can evaluate the prognosis of the anomalous origin coronary artery.
