Features

  • Low valve profile facilitates ease of implant and improved valve sizing for each patient’s anatomy.1–3,6
  • Industry-leading effective orifice areas (EOAs) and a large internal diameter can help increase cardiac output for patients as demonstrated by the Avalus™ valve.3,4,7
  • Amino olecic acid (AOA™) anti-calcification tissue treatment helps reduce calcification in the tissue leaflets.†,8–13
  • The platinum iridium radiopaque coil and tantalum badge help enhance visibility of the Avalus Ultra™ valve on fluoroscopic imaging for potential valve-in-valve procedures in the future.1,2
  • Polyetheretherketone (PEEK) circular base frame and stent posts resist deformation to deliver long-lasting durability after implantation as demonstrated by the Avalus™ valve.4,14
  • Flexible and pliable sewing cuff facilitates needle penetration, securing valve seating and contributing to exceptionally low paravalvular leak (PVL) rates as demonstrated by the Avalus™ valve.3

Clinical evidence

Trusted performance, established in evidence

The Avalus Ultra™ valve’s design is built on the 10 years of clinical experience with the Avalus™ valve. The Avalus Ultra™ valve is supported by the robust and real-world evidence of the Avalus™ valve, which demonstrates excellent durability, industry-leading EOAs, stable low gradients, and valve circularity.4,15

Performance is based on data gathered from the Avalus™ valve.

The PERIGON 7-year results ​

The PERIGON Pivotal trial is the largest prospective study of any contemporary stented surgical valve to date — 1,312 patients at 39 centers across 8 countries.4 Nineteen of those sites agreed to participate in long-term follow-up (> 5 years), and 576 patients were re-consented.

Compared to other SAVR valves and studies, the Avalus™ valve leads with a combination of longer patient follow-up, more patients enrolled, and more robust comparative data.

Objectives

Safety, efficacy, and durability are important considerations when selecting a bioprosthesis for aortic valve replacement (AVR). This study assessed seven-year clinical outcomes and hemodynamic performance of the Avalus™ bioprosthesis.

Methods

Patients indicated for surgical AVR were enrolled in this prospective, nonrandomized trial, conducted across 39 sites globally. The primary endpoint of this analysis was freedom from surgical explant or percutaneous valve-in-valve reintervention due to structural valve deterioration (SVD) at seven years of follow-up, determined using Kaplan-Meier (KM) analysis. We also evaluated a composite endpoint of SVD or severe hemodynamic dysfunction (SHD) requiring reintervention. Survival, valve related safety events, and hemodynamic performance were assessed. Deaths and safety events were adjudicated by an independent clinical events committee.

Results

A total of 1,132 patients underwent surgical AVR. Mean age was 70 years; 854 patients (75%) were men. Mean STS risk of mortality was 2.0 ± 1.4%, and 659 patients (58%) had a NYHA classification of I/II. One or more concomitant procedures were performed in 577 patients (51%). At seven years, the KM rate of SVD/SHD‡ requiring reintervention was 1.2% (0.5–2.5%) with no cases adjudicated as SVD. The survival rate was 82.6% (79.5–85.0%). The KM event rate was 5.7% (4.3–7.7%) for reintervention, 6.3% (4.9–8.3%) for endocarditis, and 0.4% (0.1–1.1%) for valve thrombosis. Mean aortic gradient, dimensionless velocity index, and effective orifice area were 13.8 ± 5.9 mmHg, 0.42 ± 0.09, and 1.99 ± 0.53 cm2, respectively.

Conclusions

This analysis demonstrated excellent durability of the Avalus™ valve with excellent clinical outcomes and stable hemodynamic performance through seven years of follow-up.

Risks may include infection, surgical complications, stroke, endocarditis, and death.

‡ Structural valve deterioration (SVD) was defined as a confirmed intrinsic abnormality causing stenosis or regurgitation. Severe hemodynamic dysfunction (SHD) was defined as severe stenosis and/or severe transvalvular regurgitation and/or reintervention without adequate evidence to adjudicate SVD, nonstructural valve dysfunction, endocarditis, or valve thrombosis.
