Contemporary trends and in‐hospital outcomes of mechanical and bioprosthetic surgical aortic valve replacement in the United States

摘要

Abstract Introduction The choice between a mechanical versus a bioprosthetic valve in aortic valve replacement (AVR) is based on life expectancy, bleeding risk and comorbidities, since bioprosthetic AVR (bAVR) are associated with a more rapid structural deterioration compared to mechanical AVR (mAVR). The impact of widespread transcatheter valve replacements, on the decision to use bAVR versus mAVR, in the contemporary era and subsequent outcomes remain to be determined. Methods The National Inpatient database (2009–2018) was used to study trends in admissions for bAVR and mAVR and in‐hospital mortality and outcomes over time. Survey estimation commands were used to determine weighted national estimates. Results There were 700,896?±?18,285 inpatient visits for AVR with 70.1 (95 CI 69.2–71.1) and 29.9 (95 CI 28.9–30.8) visits for bAVR and mAVR, respectively. Those undergoing bAVR were significantly older (bAVR 69.8?years vs. mAVR 62.7?years p?
