The FREEDOM has clearly established the benefit of myocardial revascularization surgery (CABG) over percutaneous coronary intervention (PCI) in diabetic patients with multivessel disease. Coronary physiology as guideline for revascularization works best precisely in this kind of patients and its impact has never been studied in diabetics. This study, published in Circ Cardiovasc Interv, assessed the…
ACC 2018 | DEFINE-FLAIR Sub-Analysis: iFR More Comfortable, Faster, and Much Cheaper
Using instantaneous wave-free ratio (iFR) to guide decisions on revascularization of intermediate lesions is cheaper than using fractional flow reserve (FFR). Based on costs from the DEFINE-FLAIR trial, researchers estimate the difference to be almost USD 1000. This should not be seen as good news for any given technology (iFR, in this case), but for physiologic…
Contrast Induced FFR: Cost and Time Effective Alternative
Courtesy of Dr. Guillermo Migliaro. Fractional flow reserve (FFR) is the radio of two flows expressed as the ratio of two pressures ─ distal pressure across stenosis (Pd) to aortic pressure (pa) ─ obtained only under maximal coronary hyperemia, which is a state of drug induced maximal vasodilation. The gold standard to create…
