Abstract
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.
