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.
泰尔茂血管内超声（IVUS）ViewIT 因其低轮廓和表面涂层而有助于经皮冠状动脉介入治疗（PCI）中的慢性完全闭塞（CTO）的导丝引导。在 CTO 的 PCI 中，第一根导丝有时会插入到内膜下空间，通过第一根导丝在内膜下进行 IVUS 观察，可以使第二根导丝在直视下进入真腔。我们描述了一例 CTO 病例，在该病例中，将 ViewIT 插入 CTO 病变的内膜下空间，从冠状动脉口到 CTO 内膜下空间进行扫描，使第二根导丝进入真腔。
