A Fractional Flow Reserve Guidewire Causing Longitudinal Stent Compression and Successful Recovery

Metzdorf Pierre-Adrien et al. Heart Views. 2017 Apr-Jun.

Abstract

Longitudinal stent deformation (LSD) is a rare complication but can occur during coronary intervention. We report a case with LSD of the distal edge, documented by an optical coherence tomography investigation and successfully recovered.

Keywords: Optical coherence tomography imaging; percutaneous coronary intervention; stent deformation.
