Original research article: Prognostic impact of postprocedure stroke volume in patients with low-gradient aortic stenosisDOI: 10.1136/openhrt-2018-000988 Keywords: aortic stenosis, echocardiography, transcatheter valve interventions Abstract: The effect of postoperative blood flow status on the prognosis of patients with low-gradient severe aortic stenosis (AS) has not been examined. Severe AS is associated with a higher mortality rate after transcatheter aortic valve implantation (TAVI). We examined the prognostic value of low-flow status by comparing stroke volume indices (SVi) before and after TAVI in patients with symptomatic, low-gradient severe AS
