Zusammenfassung

Background: This study aimed to assess the stability of pressure derived fractional flow reserve (FFR) measurement and the handling performance of the OptoWire Deux with an optical pressure sensor relative to the PressureWire X with piezo resistive pressure sensors.

Methods: This multicenter centre observational study included 50 patients between June 2017 and November 2018 undergoing a diagnostic coronary angiography with FFR measurement of moderate to severe lesions.

The reliability of FFR measurement measured with the OptoWire Deux relative to the PressureWire X in each lesion was assessed by the presence of drift.

Handling characteristics for both pressure wires were assessed by a 5-point scale and by comparing the time between equalization and crossing the distal target lesion.

Results: Hundred and sixteen measurements in 50 patients were performed.

Very stable and reliable FFR measurements with the optical sensors were registered, relative to the piezo resistive pressure sensors.

There is statistically significant difference in favor of the OptoWire Deux over the PressureWire X (P=0.001).

However, the differences are small, when drift values were compared as continuous variables, no statistically significant difference was found for both directional (P=0.435) as for absolute drift (P=0.058).

Conclusions: In patients undergoing FFR measurement, both optical sensor pressure wires (Optowire Deux) as piezo resistive sensor pressure wires (PressureWire X) generate stable and reliable pressure and thus FFR measurement.

The optical pressure sensor is less susceptible for drift relative to the piezo resistive pressure sensor, but the difference is within an acceptable range.
