Abstract

Objectives:

This study aimed to investigate the practical usefulness of dual lumen catheter-facilitated reverse wire technique.

Background:

We sometimes encounter difficulty in introducing a guidewire to the highly angulated side branch. In those cases, the reverse wire technique is considered as a last resort to overcome the situation.

Methods:

Between January 2013 and June 2015, we performed the reverse wire technique for guidewire crossing into an extremely angulated side branch in consecutive seven cases with true bifurcated lesions. We retrospectively evaluated patients’ backgrounds, lesion characteristics, and details of the percutaneous coronary intervention (PCI) procedures.

Results:

Three interventional cardiologists with various levels of experience in coronary intervention performed this technique. A polymer-jacket hydrophilic-coated guidewire was used for the reverse wire system excluding in one case, and we adopted a sharp curve for the tip shape in all cases. After crossing the reverse wire into a highly angulated side branch, we usually deliver a flexible micro catheter over the guidewire for the purpose of guidewire exchange. We deployed a stent in the side branch in three cases. We successfully performed all PCI procedures without any complications and no major adverse cardiac event was observed during hospitalization.

Conclusions:

We could safely and effectively perform the reverse wire technique for guidewire crossing into a markedly angulated side branch. We recommend a polymer-jacket hydrophilic-coated guidewire with a sharp curve in the tip shape for this technique. All interventional cardiologists should acquire knowledge and skills regarding this guidewire manipulation technique. (J Interven Cardiol 2015;28:544–550)
