FFR Technologies

This channel includes news and new technology innovations for fractional flow reserve (FFR) wires, catheters and systems used to measure blood flow across a coronary lesion to determine if a stent is needed or if the plaque stenosis can be treated medically. The section includes iFR, instantaneous wave-free ratio, systems used in the cath lab and noninvasive FFR technologies including computed tomography-FFR. This is also referred to as CT-FFR or FFR-CT.

Two examples of CT myocardial perfusion (CTP) imaging assessment software. Canon is on the left and GE Healthcare is on the right. Both of these technologies have been around for a few years, but there have been an increasing amount of clinical data from studies showing the accuracy of the technology compared to nuclear imaging, the current stand of care for myocardial perfusion imaging, and cardiac MRI.

An example of FFR-CT imaging from Beaumont Hospital in Royal Oak, Mich. The left image shows a 3D generated image of the coronary tree from a CT scan evaluated with computational fluid dynamics to determine the FFR numbers. It shows a severe restriction of the left main artery which requires a stent to revacularize. The image on the right is a comparison with the invasive angiogram from the cath lab prior to stenting.
