Fractional flow reserve (FFR) is the current gold standard for correct decision making with respect to revascularization in the catheterization laboratory. FFR is measured by using a pressure guidewire equipped with a pressure sensor, positioned distal to the stenosis under investigation. A newly developed pressure wire using open wire technology has recently become commercially available. The purpose of this study is to evaluate whether the Wirecath pressure guidewire can be used as standard pressure guidewire.
The effectiveness of the device will be investigated by comparing Wirecath FFR measurements with the measurements of another regular sensor-tipped pressure guidewires during simultaneous FFR measurements in the same vessel.

In summary, the purpose of the study is to evaluate whether the Wirecath device can be used as a standard pressure wire in a safe and efficient way.
