Vessel Fractional Flow Reserve and Graft Vasculopathy in Heart Transplant Recipients

Figure 2

(a) Normal coronary angiogram with functionally significant CAV according to the vFFR analysis. The LAD shows no stenosis on angiography; however, the vFFR shows diffuse pressure losses, and the distal vFFR value is 0.79. (b) Normal angiogram without functionally significant CAV according to the vFFR analysis. The LAD shows no stenosis on angiography, and the vFFR shows small pressure losses resulting in a distal FFR value of 0.88. CAV, cardiac allograft vasculopathy; LAD, left anterior descending coronary artery; and vFFR, vessel fractional flow reserve.
