Web18 apr. 2024 · Definition Der Instantaneous wave-free ratio, kurz iFR, ist ein Indexwert zur Bewertung von Koronarstenosen bei Patienten mit koronarer Herzkrankheit (KHK). Er wird im Rahmen einer Linksherzkatheteruntersuchung bestimmt. Hintergrund WebInstant wave-free ratio (iFR) is one of these methods that obviates the need for a hyperemic agent such as adenosine. The iFR is calculated by measuring the resting pressure gradient across a coronary lesion during diastole when microvascular resistance is low and stable [40,41].
WebINSTANTANEOUS WAVE-FREE RATIO Recently, iFR was introduced as a nonhyperemic alternative to FFR. This index is calculated as the ratio of resting Pd to aortic Pa over a specific period in late diastole (the so-called “wave-free period”) during which intracoronary resistance is reportedly constant and “minimal.” WebInstantaneous wave-free ratio (iFR®) to determine hemodynamically significant coronary stenosis: A comprehensive review World J Cardiol 26.
