Successful retrieval of an entrapped guide wire between a deployed coronary stent and severely calcified vessel wall using excimer laser coronary atherectomy

We report the successful retrieval of an entrapped interventional guide wire between a newly deployed coronary stent and severely calcified vessel wall. Using a buddy wire technique, the stent was deployed at high pressure in a culprit lesion of the left anterior descending (LAD) artery. The buddy wire in the LAD artery was entrapped between the deployed stent and severely calcified vessel wall, as it was not removed before stent deployment, and could not be retrieved. Neither balloon catheters nor a microcatheter were able to be advanced behind the stent over the entrapped guide wire. Excimer laser coronary atherectomy (ELCA) was performed within the stent to modify and soften the calcification behind the deployed stent. Consequently, the entrapped guide wire was retrieved successfully and safely. This case illustrates that ELCA can be utilized to retrieve an entrapped guide wire between a deployed stent and calcified vessel wall. © 2014 Wiley Periodicals, Inc.
