Intravascular Imaging vs Angiography Guidance for PCI of Severely Calcified Lesions

IVI guidance during PCI of severely calcified lesions was associated with improved 1-year clinical outcomes compared with angiographic guidance alone, whether OA or BA was used for vessel preparation prior to drug-eluting stent placement. The adjusted difference in 1-year TVF rates were not significantly different with optical coherence tomographic guidance and IVUS guidance.
