Key result
Post-PCI FFR unmasks hidden left main stenosis, guiding stenting to achieve final FFR of 0.85.
Why the study?
Patients with severe left ventricular dysfunction frequently undergo coronary angiography to rule out coronary artery disease.

Post-PCI FFR may reveal occult left main stenosis after branch stenting; leaves open its systematic role in severe LV dysfunction.
CASE REPORT Open Access Volume 1 | Issue 1 ScholArena | www.scholarena.com Journal of Cardiac Disorders and Therapy 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.

Zsolt Piróth (2018) conducted a case report in Severe left ventricular dysfunction and coronary artery disease (n=1). Fractional flow reserve (FFR)-guided percutaneous coronary intervention (PCI) was evaluated on Post-PCI fractional flow reserve (FFR) and 3-year angiographic patency. Post-PCI FFR measurement after diagonal stenting (FFR 0.33 to 0.72) unmasked a significant left main ostial stenosis, and subsequent left main stenting achieved a final FFR of 0.85.
