In this study patient population, a pre-operative oral carbohydrate drink did not reduce post-operative insulin resistance or post-operative nausea and vomiting. According to our findings, it is safe to allow cardiac surgery patients to drink clear fluids up to 2 h before induction of anaesthesia, because gastric emptying of the drink was almost total and no aspiration occurred.
Levosimendan improved haemodynamics compared with a placebo in patients undergoing high-risk cardiac surgery. The concentrations of levosimendan's metabolites were higher compared with earlier studies using perioperative dosing.
Aims:The aim of this study was to compare the risk of prosthetic valve endocarditis (PVE) in patients with transcatheter aortic valve replacement (TAVR) or surgical aortic valve replacement (SAVR).
Methods and results:The FinnValve registry included data from 6,463 consecutive patients who underwent TAVR (n=2,130) or SAVR (n=4,333) with a bioprosthesis from 2008 to 2017. PVE was defined according to the modified Duke criteria. In this study, the incidence of PVE was 3.4/1,000 person-years after TAVR, and 2.9/1,000 person-years after SAVR. In competing risk analysis there was no significant difference in the risk of PVE between patients with TAVR and SAVR over an eight-year observational period. Male gender (HR 1.73, 95% CI: 1.04-2.89) and deep sternal wound infection or vascular access-site infection (HR 5.45, 95% CI: 2.24-13.2) were positively associated with PVE, but not type of procedure (HR 1.09, 95% CI: 0.59-2.01) in multivariate analysis. The mortality rate was 37.7% at one month and increased to 52.5% at one year. Surgical treatment was independently associated with decreased in-hospital mortality (HR 0.34, 95% CI: 0.21-0.61).
This comparative effectiveness cohort study examines 30-day and 3-year survival among Finnish patients with aortic stenosis at low operative risk who underwent transcatheter aortic valve replacement compared with surgical aortic valve replacement.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
