4 options to crossing CTOs

IC-185422-AA SEP2013

• Approach from collateral channel

• Usually for RCA and LAD via septals (easier for RCA),

or via Grafts

• Easier to penetrate distal cap than from antegrade

approach

• Be aware with anticoagulation (ACT>350)

W balloon catheter through the channel

Retrograde Approach

Retrograde accessories

• Colateral wires (Fielder FC, XT-R, Sion family, Suoh)

• Externalization wires : RG3, R350

• Guide extensions

• Microcatheters (single and dual lumen)

• Snares

• Perforation tools

Retrograde wires

Sion black Suoh 03

Wire collateral crossing• Septal surfing technique

• Selective contrast injection

Solving Microcatheter problems• Choose guide catheters with good support

• Change the failing mc

• Choose another collateral pathway

• Baloon anchoring

CTO Lesion Crossing

• Retrograde wire escalation

• Retrograde dissection and reentry

CART

Reverse CART

Wire ExternalizationUse of Guide extension or snare

Trapping the micro in the guide

Loading from the tip of the wire or cut it

IVUS applications in retrograde approach

• Retrograde guidewire crossing

ostial occlusions or bifurcations with blunt stump

• Reverse CART

evaluation of antegrade and retrograde guidewires positions compared with CTO body and optimal balloon sizing for medial disruption

selection of the appropriate position within CTO vessel where to create connection between antegrade and retrograde guidewires

Gaia 2nd,3rd failed but a Pilot 150 succeeded to pass retro. The micro was driven inside the guide with wire trapping and RG3 was externalized
