A Negative FFR (Intracoronary Adenosine Bolus)

subject

description

This case describes the assessment of FFR for a single intermediate stenosis in the mid LAD. Since the procedure was performed using a radial access, and given the history of asthma, we preferred to use intracoronary adenosine as the vasodilator of choice. A first bolus of 50 μg was given, followed by a second one of 140 μg. The FFR was reproducible at 0.93, demonstrating that the stenosis was not relevant from the hemodynamic perspective.
