Safety and Feasibility of Coronary Lithotripsy Supported by Guide Extension Catheter for the Treatment of Calcified Lesion in Angulated Vessel.

We report a case of successful coronary intervention with coronary lithotripsy facilitated by guide extension catheter for the treatment of severely calcified and bent vessel. Even though lithotripsy balloon currently available is relatively bulky, the contemporary rapid exchange guide extension catheter accommodated it with ease and helped smooth delivery of it. The present case showed the usefulness of this device combination for patients with complex coronary anatomies.
