Recanalization of chronic and long occlusive in‐stent restenosis using optical coherence reflectometry‐guided radiofrequency ablation guidewire

Abstract

Chronic total occlusions remain a challenge to interventionalists due to failure of crossing or perforation by strong wires. We describe the use of a system using optical coherence reflectometry for navigation and radiofrequency ablation to enable wire passage through occlusions that could not be crossed by conventional guidewires.
