Overview
How to Engage the Right Coronary Artery
The Right coronary artery (RCA) is engaged in the left anterior oblique (LAO) position.
Optimal Views of the Right Coronary Artery
The following sequence of views is obtained as the gantry is swung from the 30o position to the AP cranial position with cranial angulation to the RAO 30 position.
Proximal RCA
The proximal RCA including the ostium is best visualized in the LAO 30 view with no cranial or caudal angulation.
Bifurcation of the RCA
The bifurcation of the distal RCA where the right posterolateral artery and the posterior descending artery originate is best visualized using 30 o of cranial angulation and no right or left angulation (the anteroposterior (AP) 0 cranial 30o view).
Mid RCA
The middle RCA is best visualized in the straight right anterior oblique (RAO) 30 oview.
RCA LAO View
Initial angiographic imaging of the RCA in the LAO 30 projection gives the best view of significant ostial and proximal RCA disease.
RCA RAO View
The mid RCA is best visualized in the straight RAO 30 position.
RCA AP 0 Cranial 30 View
The bifurcation of the distal RCA and rPDA is best seen in the AP 0 Cranial 30 view with a small breath in.
