Fractional flow reserve noninferior to intravascular ultrasonography for guiding percutaneous coronary intervention

Fractional flow reserve noninferior to IVUS for guiding PCI

For patients with intermediate coronary stenosis being evaluated for percutaneous coronary intervention (PCI), fractional flow reserve (FFR) guidance is noninferior to intravascular ultrasonography (IVUS) guidance for a composite cardiovascular outcome, in accordance with a report published in the Sept. 1 problem of the New England Journal of Medicine.

Bon-Kwon Koo, M.D., from the Seoul National University Hospital in South Korea, and colleagues randomly assigned 1,682 who have been being evaluated for PCI for the treating intermediate stenosis to endure either an FFR-guided or IVUS-guided procedure, that was used to find out whether to execute PCI. A composite of death, , or revascularization at 24 months after randomization was examined because the primary outcome.

The researchers discovered that the frequency of PCI was 33.2 and 58.4 percent among all target vessels in the FFR and IVUS groups, respectively. A primary outcome event had occurred in 8.1 and 8.5 percent of patients in the FFR and IVUS groups, respectively, at 24 months (absolute difference, 0.4 percent; upper boundary for one-sided 97.5 percent confidence interval, 2.2 percentage points, which met the noninferiority criteria). The groups had similar patient-reported outcomes on the Seattle Angina Questionnaire.

“Among patients with intermediate coronary stenosis, FFR guidance was noninferior to IVUS guidance regarding a composite of death, myocardial infarction, or any revascularization at 24 months following the index procedure,” the authors write.

The analysis was funded by way of a grant from Boston Scientific.
