FFR in Everyday Use: The Case of Left Ventricular Dysfunction

Patients with severe left ventricular dysfunction frequently undergo coronary angiography to rule out coronary artery disease. Here we describe the case of a 58-year-old man without angina and any non-invasive proof of myocardial ischaemia who was sent for invasive coronary angiography. Apart from the subtotal, proximal occlusion of the dominant right coronary artery, a 70% diagonal stenosis was found. After RCA PCI, FFR-guided diagonal PCI was also carried out. Post-PCI FFR however revealed the hitherto unnoticed significant left main ostial stenosis and allowed complete functional revascularisation.
