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

Figure 1

Intracoronary pressure measurements. FFR was measured in the supine position. Subsequently, patients were turned to a prone position. To ensure that the pressure wire’s sensor is located in the same sites, side branches or tortuous parts were used as landmarks; then, FFR was similarly measured. FFR, fractional flow reserve.
