Optical coherence tomography enables more accurate detection of functionally significant intermediate non-left main coronary artery stenoses than intravascular ultrasound: A meta-analysis of 6919 patients and 7537 lesions.

•FFR allows accurate physiological assessment of intermediate coronary stenosis.•IVUS and OCT allow accurate assessment of vessel geometry and plaque morphology.•IVUS and OCT-derived MLA have similar sensitivity to detect flow limiting lesions.•OCT-derived MLA has the best diagnostic accuracy to identify significant stenosis.•The superiority of OCT-derived MLA is not affected by vessel size.
