Overview
The Right coronary artery is engaged in the LAO position. Proximal RCA disease is best visualized in the LAO 30 view and the mid RCA is best visualized in the straight RAO 30 view. The bifurcation of the distal RCA and rPDA is best seen in the AP 0 Cranial 30 view.
Right Coronary Artery
The right coronary artery (RCA) appears like a letter C in the LAO projection and appears like a letter L while in the RAO projection. To expose the ostial and proximal part of the RCA, an LAO projection with caudal angulation is deployed. The distal segment of the RCA and the bifurcation into the posterior descending artery (PDA) may be exposed in an LAO cranial view coupled with deep inspiration. An AP projection with cranial angulation is required to completely expose the right posterolateral (RPL) branches of RCA.
RCA LAO View
Initial angiographic imaging of the RCA in this view (LAO 30) gives the best view of significant ostial and proximal RCA disease.

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.
