Coronary guidewire circumcision during use of a Gopher support catheter: potential adverse interaction with polymer-jacketed wire design

Abstract

Support catheters with a threaded, distal tip may be useful for crossing recalcitrant coronary lesions. The interaction between the Gopher support catheter and polymer-coated coronary guidewires may, however, result in circumferential stripping of polymer from the guidewire, with resulting wire damage or fracture. We report two cases of polymer-coated guidewire damage with use of a Gopher support catheter, suggesting that these two devices should not be used together.
