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

Table 3

Height and pressure differences between distal pressure sensor and catheter tip.

Height differences (Pa–Pd) (mm)(mmHg)

LAD ()−47.8 ± 14.63.7 ± 1.1
LCX ()+23.5 ± 8.51.8 ± 0.7
RCA ()+29.2 ± 9.42.3 ± 0.7

Data are expressed as mean ± SD. In the position where Pd is higher than Pa, it is represented by a minus sign, whereas in the position where Pd is lower than Pa, it is represented by a plus sign. LAD, left anterior descending artery; LCX, left circumflex artery; RCA, right coronary artery; Pa, mean aortic; Pd, mean distal intracoronary pressure.
