Safety of Next-Day Discharge After Transfemoral Transcatheter Aortic Valve Replacement With a Self-Expandable Versus Balloon-Expandable Valve Prosthesis

Background: The safety of next-day discharge (NDD) after transcatheter aortic valve replacement (TAVR) with a self-expandable valve is unknown. We investigated the safety of NDD after TAVR in patients who received a self-expandable valve or balloon-expandable valve. Methods and Results: We retrospectively evaluated consecutive patients who underwent elective minimalist TAVR between January 2017 and July 2018. We investigated the success rates and predictors of NDD after TAVR. Ninety-day and 1-year outcomes in patients managed with NDD after self-expandable ACURATE neo or balloon-expandable SAPIEN 3 replacement were compared. In 315 TAVRs, 249 patients received an ACURATE neo (n=146) or SAPIEN 3 (n=103) valve. There were no differences in baseline characteristics. In the ACURATE neo and SAPIEN 3 groups, NDD was achieved in 60% (n=87) and 55% (n=57) of patients, respectively (P >0.50). Predictors of NDD included chronic obstructive pulmonary disease (odds ratio, 0.49; 95% CI, 0.25–0.94) and low pre-TAVR hemoglobin (odds ratio, 0.98; 95% CI, 0.96–0.99) but not type of valve (odds ratio, 1.20; 95% CI, 0.71–1.98 for ACURATE neo). After excluding non-NDD cases, there were no significant differences in 90-day mortality (0% versus 0%;P >0.90) or new pacemaker implantation (1% versus 0%;P >0.40) between ACURATE neo and SAPIEN3, respectively. No significant difference in 1-year mortality between ACURATE neo and SAPIEN 3 groups after NDD (8% versus 10%; log-rank,P >0.80) was observed.Conclusions: The safety of NDD using ACURATE neo was similar that using SAPIEN 3, with comparable 90-day and 1-year outcomes.
