Figure Lengend Snippet: Case example. Two patients both with anatomically obstructive stenosis (arrow) on coronary computed tomography angiography (CCTA) ( A and D ). In the first patient ( A–C ), computation of fractional flow reserve from coronary computed tomography angiography (CT-FFR) demonstrates lesion-specific ischaemia of the middle left anterior descending (LAD) stenosis, with a value of 0.74 ( B ). Invasive coronary angiography confirms the functionally obstructive stenosis with an invasive FFR of 0.71 ( C ). In the second patient ( D–F ), CT-FFR predicts no ischaemia of the stenosis in the distal right coronary artery (RCA) with a CT-FFR value of 0.94 ( E ). Invasive FFR of 0.92 similarly demonstrates no ischaemia of RCA.
