A Case-Based Illustration of a Dual-Operator, Dual Microcatheter Technique for Side Branch Wiring.

Wiring a side branch through a dual lumen microcatheter is typically performed in sequential fashion: the microcatheter position is modified, followed by wiring attempts, all performed by a single operator. We describe a dual operator technique, in which positioning of the dual lumen microcatheter and guidewire advancement are performed simultaneously. This method can be used for particularly challenging wiring scenarios. We provide two case examples illustrating how this technique could facilitate the success and efficiency of side branch wiring.
