    Meta-Analysis Investigating the Role of Optical Coherence Tomography Versus Intravascular Ultrasound in Low-Risk Percutaneous Coronary Intervention

    Intravascular ultrasound (IVUS) guidance during percutaneous coronary intervention (PCI) provides a superior assessment of coronary artery dimensions, plaque morphology, and optimal stent expansion compared with coronary angiography. Optical coherence tomography (OCT) was developed as an additional intravascular imaging tool for PCI guidance. 1 Several studies have demonstrated improved clinical outcomes with OCT-guided PCI compared with angiography-guided PCI. 2 , 3 The axial resolution provided by OCT is 10 times higher than that by IVUS; hence, OCT can detect fine details such as edge dissections and tissue coverage of stent struts that may be missed by IVUS imaging. However, OCT has less ...
