The correct answer here is Normal.

The RAO Caudal projection demonstrates a normal left coronary system

The LAO/Cranial projection demonstrates a normal, right dominant coronary that bifurcates into the PDA and PLB. From this image it appears that a JR4 catheter was used to engage the right coronary. There may be a kink from the JR4 catheter or some tortuosity in the vessel itself proximally, but this is still within normal limits.
