Clinical Information

Patient initials or Identifier Number


Relevant Clinical History and Physical Exam

♣ 60 years old gentleman presented with angina on optimum antianginal medication.♣ Background history of previous CABG with blocked left internal mammary artery graft to the left anterior descending artery, blocked SVG to the right coronary artery, severely recurrent instent restenosis of SVG to the blocked native LCX, previous PCIs to the left anterior descending artery and SVG to the obtuse marginal (17 stents).

Relevant Test Results Prior to Catheterization


Relevant Catheterization Findings

♣ Cardiology team decided to open the CTO of the left circumflex artery.

Interventional Management

Procedural Step

♣ By using double radial approaches using EBU 3.5 guide and AL1 catheter, we were able to pass the sion blue and corsair microcatheter to the proximal jailed left circumflex after small balloon dilatations.♣ Then confianza wire to puncture the proximal cap, progressed with Gaia 2 wire and again passed the distal cap with Confianza Pro 12.♣ CTO lesion prepared with 2 mm and 3 mm NC balloons using a GuideLiner to support the delivery.♣ DES 2.75 * 26 overlapped proximally with DES 3.0 * 22 deployed with kissing balloons at the distal of the left main stem bifurcation with good result.

Case Summary

♠ Double radial approaches are useful and safe to consider for complex CTO PCIs .♠ It is possible to open the jailed CTO vessel by using microcatheter and GuideLiner .♠ It is reasonable to try to open the native CTO vessel if we have more than 10 stents in the SVG with recurrent instent restenosis.
