Role of coronary physiology in the contemporary management of coronary artery disease

Figure 1 Fractional flow reserve of an “intermediate” lesion in the left anterior descending artery. A: Fluoroscopic image obtained in the right anterior oblique projection demonstrating an angiographically intermediate stenosis (black arrow) and a pressure wire in-situ (white arrow); B: Pressure trace demonstrating a fractional flow reserve (FFR) of 0.86; C: Pressure trace demonstrating a FFR of 0.77 at maximal hyperaemia that is positive. The patient then proceeded to successful percutaneous coronary intervention of the LAD.
