This analysis demonstrates the impact of intravascular ultrasound calcium scoring on lithotripsy outcomes in calcified lesions, suggesting improved stent expansion.
Background: In Japan, intravascular lithotripsy (IVL) is indicated during percutaneous coronary intervention (PCI) for calcified lesions when the calcium score assessed by intravascular ultrasound (IVUS) or optical coherence tomography (OCT) is ≥3. This study evaluated the effectiveness of IVL in achieving optimal stent expansion in lesions with an OCT calcium score ≥3, regardless of the IVUS calcium score.
