Abstract

Background: Coronary anomalies are the causes of sudden cardiac deaths in young peoples, but usually asymptomatic. We perform this retrospective study to determine the types and prevalence of Coronary Anomalies of origin and course.

Method: The data of 9572 patients with Coronary CT-angiography by MDCT 640 Aquilion Toshiba machine were analyzed.

Results: Anomalous origin and course of coronary artery were detected in 47 (0.49%) of 9572 patients. The anomalous origins of Circumflex Artery from the RCA or the right sinus of Valsalva are most frequently visualized ( 15 pts [31.9%] ). High taking off of RCA observed in 11 pts ( 23.4% ).The RCA rising from the left sinus of Valsalva were seen in 8 pts ( 17% ).The Left Coronary Artery originates from the right sinus of Valsalva in 5 pts ( 10,6% ).The RCA arising from the LAD in 2pts (4,2% ).Absent RCA in 2 case (4.2%) and single coronary artery from LSV in one case (2.1%). The LCA rising from the Pulmonary Artery ( ALCAPA) in 2 cases and The RCA originating from the PA in one case ( RCAPA ).

Conclusion: Anomalies of coronary artery origin and course are rare but the diagnosis is very important to prevent SCD in young patients. MDCT with the Volume Rendered Images is the non-invasive modality that provides the valuable information to detect these anomalies.
