Fractional Flow Reserve: Intracoronary versus intravenous adenosine induced maximal coronary hyperemia

摘要

BackgroundFractional Flow Reserve (FFR), a measure of coronary stenosis severity is based on the achievement of maximal hyperemia of coronary microcirculation. The most widely used pharmacological agent is adenosine which is administered either by intra coronary or intra venous routes. IV route is time consuming, has more side effects and expensive. This study is undertaken to compare the two routes of administration.
