Tsutomu Fujita M.D. has been the CEO of Sapporo Cardio Vascular Clinic since 2008. His clinic provides the most advanced medical technology in the cardiovascular field. The number of catheter treatment performed in 2016 was 2,314 cases which ranked second in Japan.
This CTO was short, it was able to pass CTO with Crosser singularity. Crosser is designed for CTO device and I use as it is for, though it doesn’t ofen cross CTO lsesion easily. Well, it passed by chance in this time? Usually, when Crosser penetrates CTO, it passes in high speed like attached moving image up. However, it seems Crosser runs near intimal lip at IVUS image. The major difference with 35 knuckle of the CTO in SFA is that the short time when SFA reaches at the CTO lip and Crosser make smaller subintimalspace than 35knucke. So 14 guide wire penetrates CTO easily than 35 knuckel through the small space of subintimal. The success rate rises only for AnteGrade since we come to use Crosser.
There is difficulty to pass the GW using IVUS guide through true lumen because subintimal of 35 knuckle has large lumen so it is hard to find place the wire. You may feel freedom to operate wire in direction as you like since subintimal hole of Crosser is small. At Intimal, Confienza 9-40 with tip deflection is the one of the options to cut sharply as Japanese SAMURAI sword.
Crosser is stocked in on wire Naveed 50 not to start the tip to change the Crosser direction.
