Index of Device Efficiency: IVUS‐Based Metric to Quantify Cutting Balloon Performance in Calcified Coronary Lesions

Key Points

• To evaluate the Index of Device Efficiency (IDE) as a metric for measuring cutting balloon performance during treatment of calcified coronary lesions.
• Used intravascular ultrasound (IVUS) to derive the Index of Device Efficiency (IDE) for cutting balloons.
• Performed multiple inflations and assessed efficiency after each.
• Analyzed correlation between IDE and stent expansion outcomes.
• IDE was found to have a reproducible plateau after four inflations.
• Higher IDE values predicted optimal stent expansion.
