Optical coherence tomography-guided bifurcation stenting of a coronary artery dissection

Periprocedural guide wire-induced coronary artery dissection is a rare but potentially serious complication of percutaneous coronary intervention. Immediate stenting of the entry point is one of the therapeutic options but engaging the guide wire in the true lumen might be challenging. We report a case of a 55-year-old woman with a guide wire-induced coronary dissection that occurred during treatment of a bifurcation lesion. Optical coherence tomography was instrumental in distinguishing true from false lumen and thereby guide correct positioning of the guide wire to successfully treat the lesion using a dedicated bifurcation stent.
