~5mAt 5 years, COMMENCE results indicate a favourable safety profile and stable haemodynamic performance of a bioprosthetic valve with RESILIA tissue. Ten-year data in an extended follow-up cohort and the RESILIENCE trial with 11-year follow-up are forthcoming.
Durability: An even more important factor in valve selection
The 2021 update of the ESC/EACTS Guidelines for the management of valvular heart disease, recommends treating patients with severe aortic stenosis younger than 75 years and low risk with surgical aortic valve replacement (SAVR), simplifying the initial patient treatment pathway and preferred mode of intervention. The implication is that valve durability is now even more important because of younger patients’ greater longevity.
Edwards Lifesciences has two ongoing trials, COMMENCE and EU Feasibility, that are evaluating the longevity of a bioprosthetic valve with novel RESILIA tissue. Both trials have demonstrated a favourable safety profile and good haemodynamic performance at 5 years, with additional follow-up to be conducted up to 10 years.1,2
The COMMENCE trial
Safety endpoints, probability event-free:
COMMENCE is an FDA pivotal trial designed to evaluate the safety and effectiveness of the INSPIRIS bioprosthetic aortic valve with the novel RESILIA tissue.1 The 5-year data are now available:
· All-cause mortality 89.2%
· Major paravalvular leak 99.5%
· Endocarditis 97.8%
Improved haemodynamic performance from baseline
The absence of structural valve deterioration through 5 years* and the presence of stable gradients, plus freedom from regurgitation support durability over the observational period.
*One case of structural valve deterioration was diagnosed at postoperative Day 1,848.
The RESILIA EU Feasibility study
The RESILIA EU Feasibility study has investigated the safety and performance in aortic valve replacement patients of the bioprosthesis with the novel RESILIA tissue at 5 years.2 Here, we summarise the results at 5 years:
Stable haemodynamic performance:
Mean gradient was 14.8 ± 7.6 mmHg
Average effective orifice area was 1.4 ± 0.5 cm2
Zero structural valve deterioration events and stable transvalvular gradients were observed at 5 years.
At 5-years, results from the EU Feasibility study represent the longest follow-up of aortic valve replacement patients with RESILIA tissue and demonstrate excellent haemodynamic performance and safety outcomes.1
