WASHINGTON – Instantaneous wave-free ratio (iFR) is the new evidence-based standard of care for invasive physiologic assessment of stable coronary lesions of intermediate angiographic severity, supplanting the older fractional flow reserve (FFR) technology, Matthias Gotberg, MD, said at the annual meeting of the American College of Cardiology.
The virtually identical results of these two trials should encourage more interventional cardiologists to incorporate physiologic assessment of stable coronary lesions into their clinical practice instead of relying solely on anatomic assessment by angiography, which abundant evidence shows is insufficiently accurate in identifying hemodynamically significant lesions warranting revascularization.
FFR never really caught on because of its limitations. DEFINE-FLAIR and iFR-SWEDEHEART show that iFR overcomes those limitations, said Dr. Gotberg, director of the cardiac catheterization laboratory at Skane University Hospital in Lund, Sweden.
The two studies showed that iFR was noninferior to FFR in the 1-year composite endpoint of all-cause mortality, nonfatal MI, or unplanned revascularization. And iFR was associated with significantly shorter procedure times, less stent utilization, and markedly less patient discomfort because, unlike FFR, it doesn’t require administration of adenosine to induce hyperemia.
Indeed, in iFR-SWEDEHEART, which included more than 2,000 randomized patients in three Scandinavian countries, only 3% of the iFR group reported experiencing chest pain, dyspnea, or other forms of discomfort during their procedure, compared with 68% of the FFR group, Dr. Gotberg explains in this video interview.[[{"fid":"192539","view_mode":"medstat_image_full_text","attributes":{"height":"390","width":"100%","class":"media-element file-medstat-image-full-text","data-delta":"1"},"fields":{"format":"medstat_image_full_text"},"type":"media","field_deltas":{"1":{"format":"medstat_image_full_text"}}}]]
