Impact of hypotonic hyponatremia on outcomes in patients undergoing transcatheter aortic valve replacement: a national inpatient sample.

Background: Transcatheter aortic valve replacement (TAVR) has emerged as a major therapeutic option for treating aortic stenosis. Hyponatremia is a common electrolyte disorder closely associated with adverse cardiovascular outcomes. However, large-scale studies investigating the impact of hypotonic hyponatremia on outcomes among TAVR patients are lacking.

Weekend effect on in-hospital outcomes of transcatheter aortic valve replacement: insights from a propensity-matched national analysis.

Background: The "weekend effect" on hospital admissions has been extensively studied, showing increased risks for patients admitted on weekends than those admitted on weekdays. We aimed to assess the "weekend effect" on in-hospital outcomes in patients undergoing transcatheter aortic valve replacement (TAVR).

Methods: A nationwide cohort study was conducted using the National Inpatient Sample Database.
