The take off of the right coronary artery (RCA) varies more than the take off of the left coronary. A Judkins right 4 (JR4) curve is most often successful. High anterior origin of the RCA may necessitate the use of an Amplatz right (AR) or left (AL) curve, a Multipurpose or an Hockey‐stick catheter if a JR is unsuccessful. Guiding catheter selection for right coronary artery is shown in Figure 4.2.
