PCI to RCA CTO• A 8Fr SAL2.0SH guiding catheter (Launcher) was
engaged in the right and a EBU4.0SH-90cm guiding catheter (Launcher) in the left coronary artery through the bi-femoral approach respectivelybi femoral approach, respectively.
• At first, the antegrade approach was attempted. It wasAt first, the antegrade approach was attempted. It was tried with the Fielder XT system with Corsair. Then the guidewire was changed to ULTIMATEbros. 3g.
• But we couldn’t control the wire intentionally due to insufficient buckup of the guiding catheter not engagedinsufficient buckup of the guiding catheter not engaged coaxially.

By using the combination of a Fielder FC 0.014 inch guide-wire and a corsair 0.014 inch 1.8Fr-150cm microcatheter, The arterial lumen distal to the CTO lesion was successfully reached through the septal branch.

By exchanging the system to ULTIMATEbros 3g, t d i d i t th CTO t thretrograde wire was passed into the CTO space to then
reach the proximal true lumen.

• We wanted to insert the wire into right guiding catheter, but the right guiding catheter was not engaged coaxially due to unusual origin of RCA ostium, so the wire was not inserted into the catheterinserted into the catheter.
• The corsair was moved to ascending Aorta and the g0.014 inch-300cm Fielder FC guide-wire was inserted from left guiding catheter to iliac artery via ascending and descending Aortaand descending Aorta.

• The right guiding catheter was moved to iliac artery and EN Snare 3 loops snare catheter (6Fr, loop size 6-p ( , p10mm) was inserted.
• The snare catheter caught hold of the retrograde wire.

• So the retrograde wire was inserted into right guiding catheter lumen and then corsair microcatheter was inserted into right guiding cathetercorsair microcatheter was inserted into right guiding catheter.
• The 0.010 inch-300cm RG3 guide-wire was inserted from left guiding catheter to right guiding catheter forming wire loop (retrograde wire externalization).

ConclusionCo c us o
• We performed successful PCI for RCA CTO using retrograde wire crossing and retrograde wire captured in iliac artery . g g p y
• Using snare catheter in iliac artery was good for making wire externalization in case the retrograde wire was not insertedexternalization in case the retrograde wire was not inserted into antegrade guiding catheter.
• We must care about the position of retrograde guiding catheter. (in this case, the left guiding catheter was engaged deeply when we tried to make wire externalization)when we tried to make wire externalization)
