Retrograde recanalization of chronic total coronary artery occlusion using a novel "reverse wire trapping" technique.

Percutaneous coronary intervention (PCI) of a chronic total occlusion (CTO) remains a technical challenge for the interventional cardiologists. Recently, modified techniques based on the retrograde approach have demonstrated that this approach could increase the success rate for PCI of CTO. In the current report, we describe a novel "reverse wire trapping" technique that can help create an antegrade wire route to open CTO after the wire has passed through the CTO retrogradely, even though the retrograde balloon dilatation or antegrade wiring was unapproachable.
