Significant decrease in lipid core burden index following balloon dilation was associated with the leakage of cholesterol crystals in a patient: a case report.

ABSTRACT:

Background

Near-infrared spectroscopy (NIRS) has been used for analysis the composition of the atherosclerotic plaque in coronary arteries. However, meaning of significant decrease in max lipid core burden index at 4 mm (max LCBI_4mm) during percutaneous coronary intervention (PCI) is poorly understood.

Case summary

A 64-year-old male with unstable angina underwent coronary angiography, which demonstrated a hazy tight culprit lesion in the mid-right coronary artery. Pre-intervention NIRS-intravascular ultrasound (NIRS-IVUS) and chemogram showed plaque with high lipid burden at the culprit lesion. Then, we used a distal protection device before PCI because of high max LCBI_4mm in the lesion. After pre-dilation with a scoring balloon, repeat NIRS-IVUS inter
