Event Description
|
It was reported that the dragonfly optis imaging catheter and the pressurewire x, wireless (pwx) device were intended to be used in the left anterior descending artery (lad) lesion with mild calcification and tortuosity.The pwx device was advanced to the target lesion without issue.However, the distal marker of the imaging crossed into the radiopaque portion of the pwx device.Therefore, the imaging catheter was removed, but then the radiopaque portion of the pwx device had looped around the imaging catheter resulting in the pwx device to be removed along with imaging catheter.The procedure was completed with another unspecified device.There was no adverse patient effect and no clinically significant delay in the procedure.No additional information was provided.
