Coronary chronic total occlusion (CTO) intervention remains one of the most challenging domains in interventional cardiology. Due to the technical challenges involved and potential procedural complications, CTO percutaneous coronary intervention (PCI) attempt and success rates remain less than standard PCI. However, the use of several adjunctive tools such as intravascular ultrasound, optical coherence tomography, rotational atherectomy, orbital atherectomy, excimer laser coronary atherectomy and percutaneous left ventricular assist device may contribute to improved CTO PCI success rates or provide better hemodynamic assessment of CTO lesion (i.e., using fractional flow reserve). In this review we present the current literature describing the utility and efficacy of these adjunctive modalities in CTO intervention.
冠状动脉慢性完全闭塞(CTO)介入治疗仍然是介入心脏病学中最具挑战性的领域之一。由于涉及技术挑战和潜在的手术并发症,CTO经皮冠状动脉介入治疗(PCI)的尝试率和成功率仍低于标准PCI。然而,使用血管内超声、光学相干断层扫描、旋磨术、轨道旋切术、准分子激光冠状动脉斑块旋切术和经皮左心室辅助装置等几种辅助工具,可能有助于提高CTO PCI成功率或对CTO病变进行更好的血流动力学评估(即使用血流储备分数)。在本综述中,我们介绍了描述这些辅助方法在CTO介入治疗中的效用和疗效的当前文献。
