Coronary angiography matches IVUS in guiding PCI stent implantation

Intravascular ultrasound (IVUS) is on par with quantitative coronary angiography when it comes to guiding stent implantation, a study published March 13 in JAMA Cardiology found. Researchers led by Cheol Whan Lee, MD, from the University of Ulsan in Seoul, South Korea, found that both methods during percutaneous coronary intervention (PCI) showed similar rates of target lesion failure at 12 months. “Findings of this study suggest that a standardized quantitative coronary angiography-based PCI algorithm may be an acceptable alternative to IVUS-guided PCI, and warrants further research,” Lee and co-authors wrote. While IVUS guidance improves outcomes after PCI, the researchers noted that “many” catheterization laboratories around the world do not have easy access to the modality. They added that reimbursement policies and excessive costs may be hindering IVUS’ use as a routine tool. However, quantitative coronary angiography is “readily available” at catheterization laboratories, the research team highlighted. It added that this method also provides reliable and reproducible quantitative measures of coronary vessels. Lee and colleagues studied whether systematic implementation of quantitative coronary angiography could be an alternative to IVUS in aiding angiography-guided PCI during stent implantation. The study included 1,528 patients who underwent PCI, were enrolled in six cardiac centers from 2017 to 2021, and underwent follow-up through 2022. Of the tot...
