FFR is the gold standard (Dr. William Fearon)
Dr. William reported on the benefits of using FFR:
• A high degree of accuracy in identifying lesions that cause ischemia.
• It allows you to specify angioplasty safely.
• It improves results when compared to standard practice.
• It is technically safe, easy to perform, economical and thus provides higher profitability.
It is considered that a FFR of <0.75 ensures a sensitivity of 88% and a specificity of 100%, highly reproductive technique as demonstrated in comparative studies and a small error margin, (small range of gray area). The FAME study showed after one year, better evolution of angioplasties that were guided by FFR and not only by angiography.
Instantaneous wave-free ratio (iFR) validation studies (Dr. Justin Davies)
Dr. Justin showed in his lecture that iFR is a method that has the same precision and power to detect significant ischemia as FFR compared to other diagnostic modalities. Evaluations with iFR can be done in real time and without causing hyperemia which obviously offers practical advantages. This is a great advantage of iFR versus FFR, since there is no need to inject adenosine.
What is the FFR (CT)? Is it ready to be used? (Dr. Koo Bon Kwon)
This new method offers the advantage of integrating an imaging method for the non-invasive assessment of coronary physiology. The FFR (CT) can predict the functional importance of injury while helping plan the treatment strategy when the patient undergoes the procedure. Dr. Koo also notes that new technologies and studies are needed to complete the integration of this new approach to evaluating coronaries.
