The Avalus™ platform advantage
Two innovative valves. One evidence-backed platform.
Avalus™
bioprosthesis
Avalus Ultra™
bioprosthesis
Surgical valve performance, proven by clinical evidence
The Avalus Ultra™ bioprosthesis, our most advanced surgical valve, builds on the 12 years of clinical experience of the Avalus™ bioprosthesis. The Avalus™ platform delivers innovative technology backed by robust, real-world clinical evidence.
Clinical results that matter
The Avalus™ platform is supported by the largest prospective study of any modern stented surgical valve — the PERIGON Pivotal trial — which followed 1,132 Avalus™ valve patients.1
The seven-year results provide and demonstrate robust evidence and a proven record of hemodynamic performance and durability.
- 99% freedom from structural valve deterioration (SVD) and severe hemodynamic dysfunction (SHD) requiring reintervention1
- 97% freedom from valve-related mortality1
- 94% freedom from all reintervention1
- 83% freedom from all-cause mortality1
Real-world evidence with the ACE registry
The ACE registry, led by UZ Leuven under the guidance of Prof. Bart Meuris and Prof. Tom Verbelen, gathers prospective, multicenter data from more than 25 leading western European centers and includes 1,250 Avalus™ valve patients. This comprehensive dataset delivers robust insights into the Avalus™ valve’s performance and safety across a wide range of patient populations.
The ACE registry’s real-world findings confirm the excellent results demonstrated in the PERIGON clinical trial,1 helping ensure every clinical decision is based on what matters most — outstanding patient outcomes.2
The ultimate valve performance evaluation tool
Discover the largest dataset of contemporary surgical aortic valves analyzed by a single core lab. Using this dataset, Medtronic created a tool for cardiac surgeons that is a novel, robust instrument for evaluating valve performance.3
More than 30 years of clinical use with the AOA™ tissue treatment
Our trusted AOA™ anti-calcification tissue treatment uses amino oleic acid to help drive durable valve replacements and lifetime patient management.
This treatment is used across a suite of Medtronic bovine pericardial, porcine root, and porcine pericardial valves used in over half a million patients and counting.†
† The benefits of AOA tissue treatment have been demonstrated through animal testing. No direct clinical evaluation of the benefits of AOA treatment in humans has been conducted.
Engineered for exceptional valve performance
Developed to stay true to its form — and your expectations
When it comes to aortic valve performance, circularity is critical for seamless hemodynamics and long-term durability. Deformation can compromise performance. Unlike competitors, the Avalus™ and Avalus Ultra™ valves are uniquely engineered with a deformation-resistant polyetheretherketone (PEEK) base frame and stent posts designed for a durable, circular foundation to maintain shape and deliver consistent, reliable outcomes for your patients.1,4–9
Don’t settle for small EOAs.
The Avalus™ platform has industry-leading EOAs with 2.0 cm2 at seven years in patients with either a bicuspid or tricuspid native valve.1

n = 1,132, with 576 patients in the long-term follow-up cohort
Designed for whatever the future holds
The Avalus™ platform has the largest internal diameter for aortic tissue stented valves in its class to date.10
Research by Ebels et al., a physician-led study, confirms that the Avalus™ platform has as large as a 3.8 mm advantage in internal flow diameter in valve sizes labeled 23–29 mm over other surgical valves.4,10,11
This makes our most advanced valve, the Avalus Ultra™ bioprosthesis, an excellent solution with the largest circular foundation and deformation-resistant base frame for future TAV-in-SAV.10

Lifetime patient management
A valve designed for all SAVR patients
The PERIGON Pivotal trial included an analysis of patients who had a reintervention (surgical or percutaneous) stratified by age (≤ 65 versus > 65 years) and by cause.
The trial included 277 patients age 65 or younger and found similar rates of clinical events such as valve thrombosis, paravalvular leak, endocarditis, nonstructural valve dysfunction, or SVD/SHD requiring reintervention in younger and older patients.1
‡ There were no adjudicated cases of SVD requiring or not requiring reintervention.
