Contacts and Personal Networking Techniquesis) and the mid-to-distal LAD (70 % stenosis by QCA analysis) was performed. After treating the proximal LAD with a bioresorbable scaffold, the FFR value was positive (FFR = 0.75) in the distal LAD. FFR measurement is useful in assessing the hemodynamic significance of borderline lesions after the t

Setting the Stage: How to Perform Intracoronary Pressure Measurementsd iFR are generally easy to perform and interpret, but, as with all other technologies, oversimplification . carries risks. In the first chapter of this book, we present the basics of FFR measurements, including basic tips and tricks, and a short introduction to the devices available on the market.

A Negative FFR (Intracoronary Adenosine Bolus)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.

The Assessment of Diffuse Disease is actually very frequent and it may affect as many as 50 % of those patients who have at least one focal lesion in another vessel. FFR in this setting may clarify the possible reason for residual angina after successful stenting.

Given the typical symptoms, FFR was performed, which allowed assessing the hemodynamic significance and the anatomic location of the stenosis. FFR-guided PCI was followed by a complete disappearance of the angina.

From the Sun to the Great AttractorA simple representative case of FFR in a high-grade stenosis. The gradient is confirmed by pushing the sensor forward. Equalization is confirmed at the end of the procedure.

The Standard Model of Particle Physics,The results of FFR measurements determine further therapies. Therefore it is important that all steps necessary to obtain correct data are respected. We show the effect of an incorrect equalization.

Mark S. Blodgett,Patricia J. CarlsonThis is a case of a long and diffuse diseased and tortuous vessel in which FFR was evaluated before and after implantation of a short stent. FFR helped identify the most serious lesion to be treated, “downgrading” a planned full-metal jacket procedure to a simpler and safer spot stenting.

The Realities of Grid Computing,The assessment of FFR for a single stenosis may also be rapid and not require hyperemia if the Pd/Pa gradient already reaches significance before the vasodilator is administered. In this case the resting Pd/Pa was 0.45, demonstrating that the stenosis was relevant even before hyperemia was achieved.
