Supports deferral of PCI for non-significant stenoses in practice; extends randomized evidence to 15-year outcomes without late catch-up.
Does deferral of PCI improve or maintain outcomes compared to performance of PCI in patients with functionally non-significant coronary stenosis?
Deferring PCI for functionally non-significant coronary stenosis remains safe over 15 years without a late catch-up phenomenon.
