Intravascular lithotripsy (IVL) has been shown to be safe and effective for calcium modification in nonocclusive coronary artery disease (CAD), but there are only case reports of its use in calcified chronic total occlusions (CTO). We report data from an international multicenter registry of IVL use during CTO percutaneous coronary intervention (PCI) and provide provisional data regarding its efficacy and safety. During the study period, IVL was used in 55 of 1053 (5.2%) CTO PCI procedures. IVL was used within the occluded segment after successful CTO crossing in 53 procedures and during incomplete CTO crossing in 2 cases. The mean J-CTO score was 3.1. CTO PCI technical and procedural success was achieved in 53 (96%) and 51 (93%) cases. Six patients had a procedural complication, with 3 main vessel perforations (5%). Two had covered stent implantation, one required pericardiocentesis, and one was managed conservatively. All had combination therapy with another calcium modification device. Two patients had a procedural myocardial infarction (PMI) (4%), and two others had a major adverse cardiovascular event (MACE) (4%) at a median follow-up of 13 (4–21) months. IVL can effectively facilitate calcium modification during CTO PCI. More data are required to establish the efficacy and safety of IVL and other calcium modification devices when used extraplaque or in combination during CTO PCI.

慢性完全闭塞经皮冠状动脉介入术中钙调质的血管内碎石术

血管内碎石术 (IVL) 已被证明对非闭塞性冠状动脉疾病 (CAD) 的钙修饰是安全有效的,但只有在钙化慢性完全闭塞 (CTO) 中使用的病例报告。我们报告了 CTO 经皮冠状动脉介入治疗 (PCI) 期间 IVL 使用的国际多中心注册数据,并提供有关其有效性和安全性的临时数据。在研究期间,IVL 用于 1053 次 (5.2%) CTO PCI 手术中的 55 次。在 53 例手术中成功穿过 CTO 后和 2 例在不完全穿过 CTO 期间,在闭塞段内使用了 IVL。J-CTO 的平均得分为 3.1。在 53 (96%) 和 51 (93%) 例中,CTO PCI 技术和程序上取得了成功。6 名患者出现手术并发症,其中 3 处主要血管穿孔 (5%)。2 例进行了覆膜支架植入,1 例需要心包穿刺,1 例保守治疗。所有人都接受了另一种钙修饰装置的联合治疗。在中位随访 13 (4-21) 个月时,两名患者发生程序性心肌梗死 (PMI) (4%),另外两名患者发生主要不良心血管事件 (MACE) (4%)。IVL 可以有效促进 CTO PCI 期间的钙修饰。需要更多数据来确定 IVL 和其他钙修饰装置在 CTO PCI 期间使用外部斑块或联合使用时的有效性和安全性。和另外两人在中位随访 13 (4-21) 个月时发生了重大不良心血管事件 (MACE) (4%)。IVL 可以有效促进 CTO PCI 期间的钙修饰。需要更多数据来确定 IVL 和其他钙修饰装置在 CTO PCI 期间使用外部斑块或联合使用时的有效性和安全性。和另外两人在中位随访 13 (4-21) 个月时发生了重大不良心血管事件 (MACE) (4%)。IVL 可以有效促进 CTO PCI 期间的钙修饰。需要更多数据来确定 IVL 和其他钙修饰装置在 CTO PCI 期间使用外部斑块或联合使用时的有效性和安全性。
