Severe restenosis after stentless treatment with coronary intravascular lithotripsy for calcified nodule lesions: a serial observation with IVUS.

ABSTRACT: An 82-year-old woman with a history of myocardial infarction presented with worsening effort angina. Coronary angiography (CAG) revealed 75% stenosis in the proximal left anterior descending artery (LAD), with intravascular ultrasound (IVUS) identifying a severe calcified nodule near a previously implanted drug-eluting stent. The lesion was treated with intravascular lithotripsy (IVL) and a drug-coated balloon (DCB), avoiding left main crossover stenting. Despite initial success, the patient experienced restenosis three months later, managed conservatively based on favorable DFR/FFR values. However, worsening symptoms led to repeat CAG, revealing 99% restenosis with calcified nodule. A second IVL was performed, followed by crossover stenting from the left main to the LAD, achieving success
