Angiogram Based Fractional Flow Reserve FFRangio - A Validation Study


About this study

In the present study we aim at validating the computation of FFRangio values from the angiogram by comparing them to measured wire-based FFR values, in a larger scale and in a completely blinded manner. Investigation of a wide range of users in various conditions may strengthen the reliability of the FFRAngio measurements.
