AI Article Synopsis
- Concomitant mitral stenosis (MS) occurs in 10-15% of patients undergoing transcatheter aortic valve replacement (TAVR), prompting a study to investigate outcomes using the Nationwide Inpatient Sample database from 2015 to 2020.
- The research compared two groups: patients with MS and those without, focusing on baseline characteristics and in-hospital outcomes like mortality, respiratory failure, and the need for pacemakers.
- Results showed that patients with MS had a higher incidence of acute respiratory failure (8.8% vs. 4.89%), complete heart block (13.54% vs. 9.36%), and permanent pacemaker placement (8.03% vs. 6.03%),
Article Abstract
Concomitant mitral stenosis (MS) is present in 10% to 15% of all patients who underwent transcatheter aortic valve replacement (TAVR). Our aim is to assess outcomes of TAVR in patients with MS using a national database. The Nationwide Inpatient Sample database was used to identify patients who underwent TAVR from 2015 to 2020. We created 2 groups, patients with and those without MS. We then compared baseline characteristics, demographics, and in-hospital outcomes of the groups. Primary outcomes were in-hospital mortality, acute respiratory failure, and pacemaker placement. Secondary outcomes were length of stay and in-hospital costs. Our study indicates that patients with MS had greater incidence of acute respiratory failure (8.8% vs 4.89%, p = 0.001), complete heart block (13.54% vs 9.36%, p = 0.01), and permanent pacemaker placement (8.03% vs 6.03%, p = 0.05). In-hospital mortality was greater in the MS group; however, it was not statistically significant (1.32% vs 1.53%, p = 0.679).
