COMPARISON OF INTRAVASCULAR ULTRASOUND-DERIVED MINIMUM LUMEN AREA AND INSTANTANEOUS WAVE-FREE RATIO IN LEFT MAIN CORONARY ARTERY DISEASE

A minimum lumen area (MLA) ≥ 6 mm2 measured by intravascular ultrasound (IVUS) has been proposed as a cut-off value to defer left main coronary artery disease (LMCA) revascularization. However, there is a lack of data evaluating correlation with the instant wave-free ratio (iFR). We conducted a
