Intravascular ultrasound-derived minimal lumen area criteria for functionally significant left main coronary artery stenosis.
OBJECTIVES This study sought to evaluate the intravascular ultrasound (IVUS) minimal lumen area (MLA) for functionally significant left main coronary artery (LMCA) stenosis using fractional flow reserve (FFR) as the standard. BACKGROUND The evaluation of significant LMCA stenosis remains challenging. METHODS We identified 112 patients with isolated ostial and shaft intermediate LMCA stenosi...

The authors assessed optimal intravascular ultrasound criteria for predicting functional significance of intermediate coronary lesions. Overall, 201 patients with 236 coronary lesions underwent intravascular ultrasound and invasive physiologic assessment preintervention. Fractional flow reserve (FFR) was measured at maximal hyperemia induced by intravenous adenosine infusion. FFR <0.80 at maxim...
