Invasive fractional flow reserve measurement.
. Your number helps your provider choose your treatment. It is positioned distally to the stenosis. While such stenoses can be better verified during invasive coronary angiography.
A fractional flow reserve assessment compares the blood flow on either side of a blockage in your coronary artery. A 0014-in pressure wire is advanced after calibration into the relevant coronary segment. If your result is less than 1 you may need medical treatment or angioplasty.
This tells your provider how severe the narrowing stenosis is in your artery.
