It was reported that a wire fracture occurred.Vascular access was obtained via the radial artery.The first 185cm comet pressure wire was selected and was advanced through a 6fr non bsc guide catheter.The first vessel that was evaluated, without any issues, was the right coronary artery.They decided to evaluate the proximal left anterior descending artery (lad); however, the comet wire was catching inside the non bsc guide catheter and appeared "fractured" 3 cm proximal from the distal tip as it emerged from the non bsc guide catheter.The comet wire did not separate and was removed intact.A 2nd 185cm comet pressure wire was selected and used with the same 6fr non bsc guide catheter.The 2nd comet wire was noted to be bent prior to use.During use of the 2nd comet wire, it also was noted to be catching inside the non bsc guide catheter and emerged from the guide appearing fractured in the same approximate location.The 2nd comet wire was removed intact as well.The procedure was completed with another of the same device.There were no patient complications.
