The reasons why fractional flow reserve and instantaneous wave-free ratio are similar using wave separation analysis
BACKGROUND AND OBJECTIVES: Fractional flow reserve (FFR) and instantaneous wave-free ratio (iFR) are the two most commonly used coronary indices of physiological stenosis severity based on pressure. To minimize the effect of wedge pressure (P(wedge)), FFR is measured during hyperemia conditions, and...
