Microcatheter balloon pinning technique to facilitate wiring of a left circumflex chronic total occlusion.

After conducting a thorough literature search, it appears that this is the first case that a microcatheter has been pinned with a balloon. We believe that in LCX CTOs that require support, the microcatheter pinning technique can provide adequate support in wiring CTO's. LCX CTOs can be very difficult to treat, we present a case of a LCX CTO that required the use of the microcatheter balloon pinning technique to allow additional wire support for successful wiring and ultimately treatment.
