Fractional flow reserve (FFR)
Fractional flow reserve (FFR) is a medical measurement used to assess how significantly a coronary artery narrowing affects blood flow to the heart. During a procedure, a thin wire with a sensor is inserted into the artery to measure pressure differences across the narrowing. This helps determine if the blockage is causing enough reduction in blood flow to need treatment, like stenting or bypass surgery. FFR provides a precise, real-time assessment, guiding doctors to make informed decisions about managing coronary artery disease efficiently, reducing unnecessary procedures and ensuring effective care.
