Fast virtual functional assessment of intermediate coronary lesions using routine angiographic data and blood flow simulation in humans: comparison with pressure wire – fractional flow reserve

Abstract: We developed a fast and simple CFD-powered virtual haemodynamic assessment model using only routine angiography and without requiring any invasive physiology measurements/hyperaemia induction. Virtual-FAI showed a high diagnostic performance and incremental value to QCA for predicting wire-FFR; this "less invasive" approach could have important implications for patient management and cost.

“…Most existing FFR computation methods for invasive coronary angiography predominantly rely on computational fluid dynamics 5, 6, 16. Inherited limitations of these methods may exist related to generating theoretical boundary conditions to create a “one‐size‐fits‐all”, and to long computation time for blood flow simulations.…”

“…Improvements on virtual FFR estimation (Morris et al, 2013;Papafaklis et al, 2014;Tu et al, 2014;Morris et al, 2015) or virtual stenting (Larrabide et al, 2012) could make these technologies available for intraoperative decision making. Real-time simulation of deployment of stent deployment and computation of the resulting hemodynamic changes by the help of 3D/4D reconstructions can be set as the next targets for clinical tool development.…”

“…Virtual FFR via non-invasive imaging (CCTA, MRA) could pave the way for a non-invasive diagnosis of moderate stenosis. On the other hand, it is also feasible to calculate virtual FFR from the 3D reconstruction obtained from invasive X-ray coronary angiography (Morris et al, 2013;Papafaklis et al, 2014;Tu et al, 2014).…”

“…auch Daten dazu liefern, ob und wann Messungen von pd/pa ohne Hyperämi-einduktion aussagekräftig sind.Gleichzeitig werden derzeit zahlreiche Verfahren zur nichtinvasiven und druckdrahtlosen FFR-Bestimmung mittels "computational fluid dynamics" (CFD), z. B. anhand von CT-Daten[73][74][75][76], 3-dimensional rekonstruierter Koronarangiogramme[77][78][79][80][81] und OCT (optische Kohärenztomographie)-Datensätzen [82, 83] evaluiert. Allerdings sind sie noch in der Phase der Entwicklung und Validierung und nicht zum klinischen Einsatz bereit.…”
