Background: Estimation of fractional flow reserve (FFR) from coronary CTA (FFR-CT) is an established method to assess coronary lesions' hemodynamic significance. However, clinical implementation has progressed slowly, partly related to offsite data transfer with long turnaround times while awaiting results. Objectives: We aimed to evaluate the diagnostic performance of FFR-CT computed onsite with a high-speed deep-learning based algorithm, using invasive hemodynamic indices as reference standard. Methods: This retrospective study included 59 patients (46 men, 13 women; mean age 66...
