Impact of Hydrostatic Pressure Variations Caused by Height Differences in Supine and Prone Positions on Fractional Flow Reserve Values in the Coronary Circulation

Figure 4

Resting Pd/Pa and FFR values in the supine and prone positions. Resting Pd/Pa and FFR values in the supine and prone positions in LAD (a, b), LCX (c, d), and RCA (e, f). Data are expressed as mean ± SD. LAD, left anterior descending artery; LCX, left circumflex artery; RCA, right coronary artery; SD, standard deviation; FFR, fractional flow reserve.
