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

<div>Anatomical position of LAD, LCX, and RCA. LAD takes an upward course, whereas LCX takes a downward course. RCA initially takes an upward course, runs horizontally, and then takes a downward course. LAD distal (Pd) is higher than the LMT ostium (Pa). LCX distal (Pd) is lower than the LMT ostium (Pa). RCA distal (Pd) is lower than the RCA ostium (Pa). LAD, left anterior descending artery; LCX, left circumflex artery; RCA, right coronary artery; LMT, left main trunk.</div>
