-
Fractional flow reserve measurement (FFR). Angiography of the right coronary artery demonstrates an intermediate-grade lesion in the mid vessel. Intermediate-grade lesions such as this should be further evaluated with fractional flow reserve measurement.
-
Fractional flow reserve measurement (FFR). RadiAnalyzer Xpress when initially powered on.
-
Fractional flow reserve measurement (FFR). PressureWire is placed outside of the guide catheter but proximal to the lesion to equalize pressure wire and aortic pressures.
-
Fractional flow reserve measurement (FFR). RadiAnalyzer Xpress demonstrating aortic and PressureWire pressures prior to crossing the lesion. Notice that the ratio is not equal to 1, indicating that further adjustments to the instruments are needed. Red line = aortic pressure. Green line = pressure at the wire tip.
-
Fractional flow reserve measurement (FFR). PressureWire is placed distal to the lesion in the right coronary artery.
-
Fractional flow reserve measurement (FFR). With the administration of intravenous adenosine, the fractional flow ratio decreases to 0.67, indicating that the lesion is hemodynamically significant and will benefit from revascularization. Red line = aortic pressure. Green line = pressure at the wire tip.
-
Fractional flow reserve measurement (FFR). Angiography of the right coronary artery after percutaneous coronary intervention.
-
Fractional flow reserve measurement (FFR). Demonstration of calibration and use of a RadiAnalyzer Xpress.
