Key clinical point: Noninvasive coronary CT angiography–derived fractional flow reserve (CT-FFR) spares pre–transcatheter aortic valve replacement patients from two invasive studies.
Major finding: CT-FFR had a positive predictive value of 68% and a negative predictive value of 82.9% for functionally significant coronary stenoses.
Study details: This prospective, single-center study included 42 patients with severe aortic stenosis who underwent both conventional invasive FFR and CT-FFR for pre–transcatheter aortic valve replacement planning.
Disclosures: The study presenter reported having no financial conflicts.
