Intravascular lithotripsy to treat an underexpanded coronary stent during index procedure: A case report study

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.
