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.
Abstract
IDE is a simple, reproducible IVUS-derived metric that quantifies CB efficiency, identifies a reproducible plateau after four inflations, and predicts optimal stent expansion.
