Aims: Treatment pathway optimisation in TAVI should include timely patient discharge with a minimised risk for out-of-hospital adverse events. The aim of this study was to define a standardised set of risk criteria that allows a safe and timely discharge, to validate their appropriateness prospectively in different centres and multiple European countries, and to assess post-discharge outcomes.
Methods and results: We defined and validated the adequacy of a set of discharge criteria and its ability to predict timely and safe discharge properly after the intervention in a prospective, European, multicentre registry. A total of 502 unselected patients were enrolled at 10 sites in three countries. The primary endpoint, defined as a composite of all-cause mortality, vascular access-related complications, permanent pacemaker implantation, stroke, re-hospitalisation due to cardiac reasons, kidney failure and major bleeding at 30 days, was reached in 12.9% of patients (95% CI: 11.3-16.5). The overall 30-day mortality was 1.1% (95% CI: 0.2-2.0), and the rates of stroke/TIA 1.7% (95% CI: -0.6 to 4.0), PPI 7.3% (95% CI: 5.8-8.9), major vascular complications 1.9% (95% CI: 0.7-3.1), major/life-threatening bleeding 2.4% (95% CI: 1.0-3.8) and cardiac re-hospitalisation 3.7% (95% CI: 1.4-6.0). Patients appropriately discharged early had a significantly lower risk of the primary endpoint (7.0 vs. 26.4%; p<0.001) which was reflected in some of its relevant components: stroke (0.0 vs. 2.8%; p=0.015), PPI (4.3 vs. 15.9%; p<0.001), major vascular complications (0.3 vs. 4.7%; p=0.004) and major/life-threatening bleeding (0.3 vs. 6.5%; p<0.001).
Conclusions: We validated the appropriateness of a pre-specified set of risk criteria that allows a safe and timely discharge. The rate of 30-day complications did not reveal any risk increase with this strategy compared with the reported outcomes in major TAVI trials and registries. ClinicalTrials.gov Identifier: NCT02404467
