Calcified and undilatable stenosis still represents a challenge in percutaneous coronary interventions (PCI), due to the higher risk of suboptimal result with consequent worse clinical outcomes. Unfortunately, the dedicated technologies and devices, such as specialized balloon and atherectomy systems, do not always provide adequate plaque modification and optimal vessel preparation allowing optimal stent delivery. The intravascular lithotripsy (IVL) is a technology derived from urology that has been tested in peripheral and coronary calcified plaques, with promising preliminary results. We present a case of a patient undergoing planned PCI of the right coronary artery targeting an undilatable lesion, already resistant to both specialized balloons and rotational atherectomy. Using the IVL system, we were able to break the calcium, guarantying optimal stent expansion with good final result.
钙化且不可扩张的狭窄仍然是经皮冠状动脉介入治疗（PCI）的一个挑战，因为结果不理想会导致更高的风险，进而导致更差的临床结局。不幸的是，专用技术和设备，如专门的球囊和旋磨系统，并不总是能提供足够的斑块修饰和最佳的血管准备，从而允许最佳的支架输送。血管内碎石术（IVL）是一种源自泌尿外科的技术，已在周围和冠状动脉钙化斑块中进行了测试，初步结果令人鼓舞。我们报告了一例计划行右冠状动脉 PCI 的患者，其目标是一处不可扩张的病变，该病变对专用球囊和旋磨术均有抵抗。使用 IVL 系统，我们能够粉碎钙，保证支架的最佳扩张，获得良好的最终结果。
