    Real-time optical coherence tomography coregistration with angiography in percutaneous coronary intervention–impact on physician decision-making: The OPTICO-integration study

    Aims Intracoronary optical coherence tomography (OCT) imaging allows for high-resolution characterization of coronary lesions. Difficulties in matching cross-sectional OCT-images with angiographic lesion localization may limit optimal clinical utilization. We sought to prospectively assess the impact of a novel system of real-time OCT coregistration with angiography (ACR) on physician decision-making during percutaneous coronary interventions (PCI). Methods and Results Strategy for PCI (stent - length, - diameter, - strategy, landing zone) and PCI-optimization (stent-malappostion, -underexpansion, edge-dissections, geographical mismatch) was prospectively assessed in 50 patients with 58 coronary lesions after (I) angiography, (II) OCT imaging, and (III) ACR. Preprocedural OCT imaging altered stent-length (58.9%), diameter ...
