Objective: The prevalence of malnutrition in patients with acute ischemic stroke (AIS) can range from 8% to 34%. It has been shown that prognostic nutritional index (PNI) and control nutritional status (CONUT) scores can provide an opportunity to make prognostic predictions in some disease groups. Previous studies have shown a close relationship between malnutrition scores and stroke prognosis.

Background: Transcatheter aortic valve implantation (TAVI) is currently the treatment of choice for the majority of patients at moderate or high surgical risk. However, some complications occur frequently with this procedure. In this study, we aimed to assess whether the cusp-overlap view (COP) technique may be associated with a reduced incidence of some of these complications compared with the classical three-cusp view (TCV) technique.
