At 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.
Exploring the in-depth analysis of 7-year data from the COMMENCE trial

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

With the publication of the 2021 update to ESC/EACTS guidelines for the management of valvular heart disease, new guidance should be considered when caring for patients with severe aortic stenosis.1
Three key recommendations stand out:
Early intervention is recommended for asymptomatic patients with a LVEF below 55% without another cause
An emphasis on Heart Team collaboration to provide the optimal treatment while informing and involving patients in their decision-making
A clear age delineation that patients younger than 75 years of age with severe aortic stenosis receive SAVR, and patients older receive TAVI
It is established that the durability of modern surgical bioprosthetic valves is over 10 years,2 and in recent years there has been a trend towards a greater use of bioprosthetic valves.3 On the other hand, mechanical valves continue to be associated with bleeding risks because of the need for lifelong anticoagulation therapy, leading to lifestyle changes.4-6
Several large, long-term studies have demonstrated up to 20-year durability for the bioprosthetic Carpentier-Edwards PERIMOUNT
aortic valve.2,7,8
Carpentier-Edwards PERIMOUNT valve
Two ongoing trials, COMMENCE and EU Feasibility, are evaluating the longevity of bioprosthetic aortic valves with novel RESILIA tissue after five-year implantation. Five-year results from these studies have demonstrated a favourable safety profile and good haemodynamic performance.9,10
INSPIRIS RESILIA aortic valve
Another study found that the INSPIRIS RESILIA valve reduced the length of hospital stay compared with mechanical valves (6.6 days versus 10.3 days).11 Selecting the right treatment for the patient requires many considerations, most importantly the desire of the informed patient.
Additionally, the Heart Team needs to consider the age, estimated life expectancy, comorbidities, and anatomical and procedural characteristics of the patient; relative risks and long-term outcomes associated with SAVR or TAVI; prosthetic heart valve durability; feasibility of transfemoral TAVI; and local experience and outcome data to achieve optimal outcomes for patients.1
