    AbstractTranscatheter aortic valve implantation (TAVI) procedures have increased exponentially since FDA approval in 2011. Older patients who underwent aortic valve replacement, either TAVI or surgical aortic valve replacement (SAVR), have elevated risk. Using the National Readmission Database, we included patients ≥80 years who underwent either TAVI or SAVR from 2011 to 2015. In-hospital outcomes of TAVI versus SAVR were compared using propensity-matched analysis to reduce the confounding effect of between-group imbalances. We identified a total of 30,590 TAVI and 54,204 SAVR procedures performed during the study period. The propensity score-matching algorithm yielded 19,713 patients in each group. The in-hospital mortality rates were significantly lower in TAVI compared with SAVR (3.4% vs 6.8%, p <0.001). Similarly, the 30-day readmission rate (15.2% vs 18.1% p = 0.001), in-hospital complications, mean length of stay (7 vs 12 days, p <0.001), and hospital cost (US$ 60,534 vs US$ 67,426) were significantly lower for TAVI patients. There was a significant increase in the use of TAVI (26 cased per month in 2011 to 1,237/month in 2015) and a decrease in SAVR (1,409/month in 2011 to 859/month in 2015) during the study period. In-patient mortality significantly decreased for patients who underwent TAVI (4.4% in 2011 to 2.5% in 2015) and did not significantly change for patients who underwent SAVR (5.0% in 2011 to 4.7% in 2015). Overall, the number of SAVR procedures remained two thirds higher than TAVI. In conclusion, in octo- and nonagenarians, TAVI is an effective and safer alternative to SAVR as it is associated with lower in-hospital mortality, lower major in-hospital complications, lower 30-day readmission rate, and hospital costs. Despite this, SAVR remained the most common approach in octogenarians, although the trends in this data set, suggest a shift in practice patterns for this cohort.Copyright © 2019 Elsevier Inc.
