Stent underexpansion, a strong predictor of adverse outcomes¹
Stent under expansion has been identified as a strong predictor of major adverse outcomes defined as cardiac death, target lesion related myocardial infarction, or stent thrombosis. Clinical studies show that achieving stent expansion with a Minimal Stent Area (MSA) superior to 5,5mm², measured with IVUS, was associated with significantly improved long term clinical outcomes compared to both underexpansion and angiography alone.
