Anomalous origins of the Coronary Arteries

Anomalous Origin of the Circumflex from the RCA

Anomalous Origin of The Circumflex Coronary Artery from the Right Coronary Artery Cusp
Axial CT of the coronary arteries shows anomalous origin of the Circumflex from the Right coronary cusp. This is the most common anomaly of the coronary arteries

Anomalies of the LCA  and RCA Inter- arterial Course

Sudden cardiac death in anomalous origin of coronary artery is associated with the anatomical features including abnormal coursing, acute angle take-off and ostial abnormalities.

Anomalies of the RCA

Anomalous Origin of The Right Coronary Artery from the Left Coronary Artery Cusp
60 year old male with a history of MI with LAD stent. Coronary angiogram suggested anomalous origin of the right coronary artery
CTA of the coronaries shows anomalous origin of the RCA from the left coronary cusp with inter-arterial course. There is narrowing of the proximal RCA as it courses between the PA and aorta

LCA off the Non Coronary Cusp

Anomalous origin of the LCA off the non coronary cusp
The CTA demonstrates the left coronary artery arising from the non coronary cusp. The RCA arises normally
