Abstract
The aim of this study was to compare in-hospital cost and outcomes between transcatheter aortic valve implantation (TAVI) and surgical aortic valve replacement (SAVR). TAVI is an effective treatment option in patients with symptomatic aortic stenosis who are at high risk for traditional SAVR. Several studies using trial data or outside United States registry data have addressed TAVI cost issues, although there is a paucity of cost data involving commercial cases in the United States. Using Agency for Healthcare Research and Quality Healthcare Cost and Utilization Project Nationwide Inpatient Sample files, a propensity score-matched analysis of all commercial TAVI and SAVR cases performed in 2011 was conducted. Overall hospital cost and length of stay, as well as procedural complications, were compared between the 2 matched cohorts: 595 TAVI patients were matched to 1,785 SAVR patients in a 1:3 ratio. There was no difference in mean ($181,912 vs $196,298) or median ($152,993 vs $155,974) hospital cost between TAVI and SAVR (p = 0.60). The TAVI group had significantly shorter lengths of hospital stay than the SAVR group (mean 9.76 vs 12.01 days, p <0.001). There was no difference in postprocedural in-hospital death or stroke, but...Continue Reading
