| Popis: | Background With the introduction of transcatheter aortic valve replacement (TAVR), the treatment of aortic stenosis (AS) has experienced a paradigm shift, altering patient selection for surgical aortic valve replacement (SAVR) over the past decade. What remains to be determined is the impact of a hospital's ability to offer TAVR, in the contemporary era, on inpatient outcomes following SAVR. Purpose The goal of this study was to assess inpatient mortality and the use of mechanical aortic valve replacement (mAVR) in patients undergoing SAVR at TAVR versus non-TAVR centers in the United States. Methods The National Inpatient Sample (2011–18), a probability sample of inpatient visits in the United States, was used to study trends in admissions for SAVR at TAVR and non-TAVR centers; in-hospital mortality was trended over time. Survey estimation commands were used to determine weighted national estimates. Results There were 559,365 inpatient visits for SAVR with 75.2% (95% CI 74.2%-76.2%) and 24.7% (95% CI 23.8%-25.8%) receiving bioprosthetic SAVR (bAVR) and mAVR, respectively at TAVR centers and 64.5% (95% CI 63.3%-65.6%) and 35.5% (95% CI 34.4%-36.7%) receiving bAVR and mAVR, respectively at non-TAVR centers. SAVR recipients at non-TAVR centers were older when compared to recipients at TAVR centers (68.3±0.09 vs 66.9±0.11 years p Conclusions Patients undergoing SAVR at TAVR centers were younger and had more co-morbidities compared to patients undergoing SAVR at non-TAVR centers. Although patients undergoing SAVR at TAVR centers had significantly more co-morbidities, inpatient mortality was lower at TAVR centers compared to non-TAVR centers. Further research is needed to determine whether the impact of a multidisciplinary cardiac approach resulted in significant differences in patient selection for SAVR, due to the availability of TAVR, influencing patient outcomes.
