It was reported that the patient underwent a coronary stenting procedure to treat a target lesion in the moderately calcified and mildly tortuous mid right coronary artery.The xience alpine stent delivery system was advanced over the balance middleweight (bmw) guide wire.The stent delivery system (sds) was unable to cross to the target lesion and an attempt was made to remove the device; however, during removal, resistance was noted between the sds and the guide wire.The physician tried to remove the sds, but the guide wire separated in the patient anatomy.The separated guide wire segment remained contained in the stent delivery system and the devices were removed as a single unit.All segments of the guide wire were removed from the patient anatomy.No portion of the guide wire remained in the patient anatomy.A second guide wire and xience alpine sds were used to complete the procedure.There was no adverse patient effect and no clinically significant delay.No additional information was provided.
