Prospective evaluation of a stiff shaft glide wire compared with the standard straight wire in crossing severely stenotic aortic valves.

In this prospective randomized study of the use of the Terumo glide wire compared with the standard straight wire for crossing of severely stenotic aortic valves, the glide wire was shown to significantly decrease the fluoroscopy time of the procedure and to lower by 3.4 times the need for crossover to the alternative technique.
