Shepherd’s Crook configuration of right coronary artery
(RCA) (a dramatic upturn with a
near-180º switchback turn) represents a challenge for the interventional
cardiologists. Because there is less support provided by the guiding catheters,
angioplasty of such artery is associated with a lower primary success rate.
Judkins Right (JR) catheter is particularly inadequate for this type of RCA
anatomy. AL1, Hockey stick, SCR, IM, Voda right, MP catheters are best suited
for this anatomy. I have an experience of doing angioplasty in such RCA using X-tra Backup (XB) catheter successfully (in two cases so far).

A Shepherd’s Crook is a very useful tool for shepherds who are navigating fields of varying height or uneven terrain. Its curved head designed to help catch a sheep by the neck or leg. The symbol is a stick with a C-curve at the top.
