Multicenter Study Comparative Study
Comparison of Causes and Associated Costs of 30-Day Readmission of Transcatheter Implantation Versus Surgical Aortic Valve Replacement in the United States (A National Readmission Database Study).
Our current knowledge about comparative differences in 30-day readmissions and the impact of readmissions on overall costs after transcatheter aortic valve implantation (TAVI) and surgical aortic valve replacement (SAVR) is largely derived from clinical trials. The objectives of this study were to compare readmissions and costs for TAVI and SAVR in a nationally representative population-based sample. The Healthcare Cost and Utilization Project's National Readmission Database was used for the study. ⋯ In multivariable analyses, the risk of 30-day readmission was similar for endovascular TAVI (odds ratio [OR] 0.93; 95% confidence interval [CI] 0.78 to 1.12) and was 27% higher for transapical TAVI (OR 1.27; 95% CI 1.02 to 1.57). Cumulative costs (index plus readmission costs) were 13% (β 0.13; 95% CI 0.10 to 0.15) and 19% (β 0.19; 95% CI 0.16 to 0.23) higher for the endovascular TAVI and transapical TAVI, respectively. In conclusion, the rate of readmissions was similar for endovascular TAVI and SAVR but the costs were 26% higher for TAVI than for SAVR.

Multicenter Study Comparative Study
Racial Comparisons of the Outcomes of Transcatheter and Surgical Aortic Valve Implantation Using the Medicare Database.
Racial disparities in the outcomes after intervention for aortic valve disease remain understudied. We stratified patients by race who underwent surgical aortic valve replacement (SAVR) and transcatheter aortic valve implantation (TAVI) in the Medicare database. The TAVI cohort consisted of 17,973 patients (3.9% were black and 1.0% were Hispanic). ⋯ Minorities were underrepresented in both SAVR and TAVI relative to what would be predicted by population prevalence. In conclusion, while blacks have worse outcomes in SAVR compared with whites or Hispanics, race did not impact mortality, readmission, or discharge to home in TAVI. Both blacks and Hispanics were underrepresented compared with what would be predicted by population prevalence.

Multicenter Study Comparative Study
Outcomes and Effects of Hepatic Cirrhosis in Patients Who Underwent Transcatheter Aortic Valve Implantation.
Comparative outcomes of transcatheter aortic valve implantation (TAVI) in patients with and without liver cirrhosis are scarce. This study aimed to assess the clinical outcomes and impact of liver cirrhosis on patients who underwent TAVI. Patient with liver cirrhosis who underwent TAVI 2011 to 2014 were identified in the National Inpatient Sample database using the International Classification of Diseases, ninth revision, Clinical Modification (ICD-9-CM). ⋯ Furthermore, cirrhotic patients were less likely to develop vascular complications requiring surgery (OR 0.47, 95% CI 0.23 to 0.98, p = 0.043), to develop after procedural deep vein thrombosis(OR <0.00, 95% CI <0.001 to <0.0001, p <0.0001), and to require pacemaker implantation. However, cirrhotic patients were more likely to undergo nonroutine hospital discharges (OR 1.50, 95% CI 1.15 to 1.96, p = 0.003). In conclusion, TAVI is a safe and reasonable therapeutic option for cirrhotic patients with severe aortic stenosis, requiring aortic valve replacement.
