Catheterization and Cardiovascular Interventions, EarlyView.ABSTRACT Heavily calcified coronary lesions remain a major challenge in percutaneous coronary intervention (PCI), often limiting the effectiveness of intravascular lithotripsy (IVL). We report a five‐case series in which IVL failed to achieve adequate lesion modification but was successfully augmented by the addition of one or more buddy wires.
