Fractional Flow Reserve, Quantitative Flow Ratio, and Instantaneous Wave-Free Ratio: Comparison of Ionising Radiation Dose
The development of interventional cardiology is inevitably associated with increased dose of ionising radiation for the physician.1 Additionally, physiology-guided myocardial revascularisation is supported by both European and American experts,2,3 but these procedures may increase the total procedure time in addition to increased dose of ionising radiation for the physician.
