Despite advances in technology, percutaneous coronary intervention (PCI) of severely calcified coronary lesions remains challenging. Rotational atherectomy is one of the current therapeutic options to manage calcified lesions, but has a limited role in facilitating the dilation or stenting of lesions that cannot be crossed or expanded with other PCI techniques due to unfavourable clinical outcome in long-term follow-up. However the results of orbital atherectomy presented in the ORBIT I and ORBIT II trials were encouraging. In addition to these encouraging data, necessity for sufficient lesion preparation before implantation of bioresorbable scaffolds lead to resurgence in the use of atherectomy. This article summarises currently available publications on orbital atherectomy (Cardiovascular Systems Inc.) and compares them with rotational atherectomy.
尽管技术不断进步，但严重钙化冠状动脉病变的经皮冠状动脉介入治疗（PCI）仍然具有挑战性。旋磨术是目前处理钙化病变的治疗选择之一，但在促进那些因长期随访临床结果不佳而无法通过其他PCI技术穿过或扩张的病变进行扩张或置入支架方面作用有限。然而，ORBIT I和ORBIT II试验中展示的准分子激光消蚀术的结果令人鼓舞。除了这些令人鼓舞的数据外，在植入生物可吸收支架前进行充分病变预处理的必要性导致了消蚀术使用的再度兴起。本文总结了目前关于准分子激光消蚀术（心血管系统公司）的可用出版物，并将它们与旋磨术进行比较。
