In vivo delamination of coronary guidewire polytetrafluoroethylene layer - A dreaded complication

Indian Heart J. 2016 Mar-Apr;68(2):182-3. doi: 10.1016/j.ihj.2015.10.303. Epub 2016 Jan 11.

Abstract

Coronary guidewires are coated with polytetrafluoroethylene (PTFE) layer to decrease resistance and enhance trackability. Delamination and embolization of PTFE material can be detrimental during percutaneous coronary interventions. We report an occurrence of such delamination and discuss the implications and possible mechanism of this dreaded complication.

Keywords: Delamination; Galeo guidewire; PTFE; Perfluorooctanoic acid; Polytetrafluoroethylene.
