Abstract

Background - Several studies have compared short-term and medium-term mortality rates for patients with severe aortic stenosis undergoing transcatheter aortic valve implantation (TAVI) and surgical aortic valve replacement (SAVR), but no studies have compared short-term readmission rates for the 2 procedures. Methods and Results - New York's Cardiac Surgery Reporting System was used to propensity match 617 TAVI and 1981 SAVR patients using numerous patient risk factors contained in the registry. The 389 propensity-matched pairs were then used to analyze differences in readmission rates between the 2 groups. TAVI and SAVR readmission rates were also compared for patients with a history of congestive heart failure and for patients aged ≥80. Also, reasons for readmission for TAVI and SAVR patients were examined and compared. Readmission rates were not statistically different for all propensity-matched TAVI and SAVR patients (respective rates, 18.8% and 19.3%; P=0.86). After further adjustment using a logistic regression model, there was still no significant difference (adjusted odds ratio, 0.97; 95% confidence interval [0.68-1.39]). For patients aged ≥80, the 30-day readmission rates were 19.9% and 22.0% (P=0.59), and when further adjusted using the logistic regression model, adjusted odds ratio=0.89 (0.55-1.45). For patients with a history of congestive heart failure, the respective rates were 22.8% and 20.4% (P=0.56), and with further adjustment, adjusted odds ratio became 1.15 (0.72-1.82). Conclusions - There are no statistically significant differences between TAVI and SAVR patients in short-term readmission rates.
