ViewIT improves intravascular ultrasound‐guided wiring in coronary intervention of chronic total occlusion

Terumo intravascular ultrasound (IVUS) ViewIT facilitates IVUS‐guided wiring in percutaneous coronary intervention (PCI) for chronic total occlusion (CTO) due to its low profile and surface coating. In PCI for CTO, the first guidewire is sometimes inserted into the subintimal space, and observation by IVUS through the first guidewire in the subintima can allow the second guidewire to be led visually into the true lumen. We describe a case of CTO in which ViewIT was inserted into the subintimal space of the CTO lesion and scanning from the coronary ostium to the CTO subintimal space allowed the second guidewire to be led into the true lumen. © 2010 Wiley‐Liss, Inc.
