Which view is used to visualize the right coronary artery from mid to distal segments?

• A. RAO view
• B. LAO view
• C. LAO cranial view
• D. Lt Lateral view

Answer: (A)

The main idea is choosing a projection that puts the right coronary artery in profile and minimizes overlap from other cardiac structures. A right anterior oblique (RAO) projection achieves this well for the RCA, allowing a clean view of the artery as it courses along the right atrioventricular groove from mid to distal segments toward the inferior wall. This orientation reduces superimposition by the right atrium and left heart structures, making it easier to trace the RCA all the way down. Other views, like left anterior oblique or lateral positions, tend to emphasize the left coronary system or cause overlap/foreshortening of the RCA, making mid-to-distal segments harder to visualize.
