Fractional Flow Reserve (FFR) is a procedure used to measure blood pressure and flow through a specific part of a coronary artery. We perform it at the time of a coronary angiogram, to assess whether or not to perform angioplasty and stenting on mid-size blockages.
Why do I need Fractional Flow Reserve (FFR)?
Fractional Flow Reserve (FFR) helps determine whether angioplasty and stenting are really necessary. These procedures aim to increase blood flow to the heart. However, studies have shown that if the flow isn’t significantly obstructed, a patient can be safely treated with medical therapy instead.
What can I expect?
Fractional Flow Reserve (FFR) will be performed at the same time as your coronary angiogram. This procedure involves inserting a very thin guide wire through a diagnostic catheter into your groin or wrist, and up into your coronary artery.
FFR uses a small sensor on the tip of the wire to measure blood pressure and flow in your artery. Results are displayed on a monitor along with the “FFR value”. Studies show that an FFR value less than 0.75 or 0.80 will most likely require interventional treatment such as angioplasty. Blockages that score above this threshold can be safely treated with medical therapy.
