The document discusses the parallel wire technique for chronic total occlusion (CTO) procedures. It was first described in 1995 in Frankfurt, Germany. The technique uses double lumen catheters to support introducing two guidewires in parallel through the occlusion. While controlled dissection reentry can fail, the parallel wire technique has a success rate of 30% in such cases and 17% of the author's own 509 CTO procedures from 2011-2015 used this technique successfully. The conclusion is that despite claims the parallel wire technique is dead, it continues to be an important technique for CTO recanalization.
