The patient underwent successful orbital atherectomy and percutaneous coronary intervention of the rca (right coronary artery), extending from ostial rca to the mid pda (posterior descending artery) with overlapping xience des.The procedure was complicated by fracture of a turnpike spiral microcatheter nose cone into the heavily calcified mid pda lesion.This was successfully treated by exclusion of the retained foreign body from the lumen of the vessel using antegrade dissection and re-entry technique.The fractured portion of the microcatheter was not removed because of the concern that snaring and pulling at the device would lead to avulsion of the vessel with the potential of death.The procedure was also complicated by wire perforation at the mid pda site.This was successfully treated with prolonged balloon tamponade and protamine infusion.The outcome was confirmed in the cath lab with definity contrast assisted tte demonstrating no extravasation of contrast of pericardium.
