Physiological assessment can be readily performed using 5 Fr and 6 Fr guiding catheters. Smaller 4 Fr catheters have been used but there is concern regards potential bailout options in the event of coronary dissection and potential for aortic waveform damping. Although the majority of pressure wire assessments are safe, wire‐related complications such as wire‐related coronary dissection or vessel occlusion occur at the rate of 0.5–1.0% [42]. The 6 Fr catheters provide a better bail‐out strategy and enable immediate percutaneous treatment without delay.
