Initial unsuccessful attempt Contralateral CFA access 6F Crossover sheath Primary GW/support catheter crossing Question: Access options: contralateral, antegrade or retrograde pedal? Crossing strategy: wire-catheter approach versus dedicated CTO crossing device strategy Escalation of symptoms after failed attempt
Repeat attempt in 4 weeks Antegrade access with 6F 45 cm sheath
Primary crossing with Viance catheter Right lateral view
Viance blunt microdissection catheter Torque Handle Distal Catheter Tip (rounded, atraumatic, 1 mm) (a) (b) 0.014” guidewire (300 cm) 135 cm shaft (2.3F) 0.035 OD: compatible with most support catheters
Subintimal passage and re-entry with Enteer Successful TP trunk re-entry with Enteer catheter & wire Followed by IVUS confirmation
IVUS confirmation of distal true lumen access Sub-intimal space s/p balloon dilation Compressed true lumen atheroma
Enteer re-entry catheter Orienting balloon with radio-opaque markers indicating wire-exit ports on diametrically opposite sides of the balloon Stingray GW with 0.0035” distal taper
Final result after distal SFA & TP trunk stenting 6x40mm nSES Two 3x38mm DES Significant improvement in patient symptoms at 3m F/U
