Navifocus WR is the promising intravascular ultrasound for navigating the guidewire into true lumen during the coronary intervention for chronic total occlusion

Cardiovascular Intervention and Therapeutics volume 29, pages 181–186 (2014)Cite this article

Abstract

We describe an initial clinical chronic total occlusion (CTO) case in which CTO-specific intravascular ultrasound (IVUS): Navifocus WR was useful for navigating the second guidewire into the true lumen under the IVUS observation from the subintimal space.
