Management of heavily calcified lesions during percutaneous coronary intervention (PCI) is often associated with high incidence of complications and long-term adverse outcomes. There is growing evidence of the efficacy of intravascular lithotripsy (IVL) in de novo coronary lesion preparation; however, little experience has been documented within freshly deployed stent underexpansion. We report a 66-year-old male with a marked stent underexpansion despite extensive lesion preparation due to severe underlying calcification. The stent was resistant to balloon postdilatation; therefore, IVL was applied, resulting in excellent stent expansion. IVL could be considered for treating acute stent underexpansion caused by severe underlying calcification.
经皮冠状动脉介入治疗（PCI）期间严重钙化病变的处理常伴有高并发症发生率和长期不良后果。血管内碎石术（IVL）在冠状动脉初发病变预处理中的疗效证据越来越多；然而，关于新植入支架扩张不全方面的经验报道很少。我们报告了一名66岁男性患者，尽管因严重的基础钙化进行了广泛的病变预处理，但支架仍明显扩张不全。该支架对球囊后扩张有抵抗；因此，应用了IVL，结果支架扩张良好。对于由严重基础钙化引起的急性支架扩张不全，可考虑使用IVL进行治疗。
