Abstract

Background: The successful percutaneous coronary intervention (PCI) in chronic total occlusion (CTO) improves the long-term outcome in patients with coronary artery disease (CAD). Heavy calcification remains one of the strongest predictors of an unfavorable outcome of PCI. In this case series study, shockwave intravascular lithotripsy (S-IVL)-a novel balloon-based coronary system facilitating modification of calcified coronary lesions was evaluated.

Methods: The study population consisted of five heavily calcified, undilatable-CTOs lesions treated with S-IVL selected out of all consecutive CTO-PCI patients performed at two high-volume cardiac centers.

Results: The registry included 5 patients successful CTO - S-IVL procedures with an average J-CTO of 2.6 points. In the short-term follow-up period, including the first 30 days, no cases of acute in-stent thrombosis, target lesion failure, or major adverse cardiac and cerebrovascular events were noted.

Conclusions: The present data suggest that this approach can be safe and useful in the treatment of complex calcified CTO lesions.

冲击波血管内碎石术作为球囊不可扩张严重钙化慢性全闭塞病变的新策略。

背景：成功的经皮冠状动脉介入治疗（PCI）可改善冠状动脉疾病（CAD）患者的长期疗效。严重钙化仍然是PCI不良结果的最强预测因素之一。在本病例系列研究中，对冲击波血管内碎石术（S-IVL）进行了评估，该术是一种新型的基于球囊的冠状动脉系统，有助于钙化冠状动脉病变的改良。方法：研究人群包括在两个大容量心脏中心进行的所有连续CTO-PCI患者中选择的五个用S-IVL治疗的严重钙化、不适的CTO病变。结果：登记包括5例成功的CTO-S-IVL手术患者，平均J-CTO为2.6分。在短期随访期间，包括前30天，没有发现急性支架内血栓形成、靶病变衰竭或重大心脑血管不良事件的病例。结论：目前的数据表明，这种方法可以安全有效地治疗复杂钙化CTO病变。
