April 23, 2024 — Medtronic plc, a global leader in healthcare technology, today announced the launch of its latest innovation in cardiac surgery, the Avalus Ultra valve. This next-generation surgical aortic tissue valve is designed to facilitate ease of use at implant and lifetime patient management. It’s an excellent choice for cardiac surgeons and their patients seeking an aortic valve solution that can be fit for the future, right from the start.
The Avalus Ultra valve is engineered for ease of implant, clear visibility for future valve-in-valve procedures, and straightforward sizing. More specifically, the Avalus Ultra surgical valve has:
- A low valve profile designed to facilitate ease of use at implant.1,2
- A polyetheretherketone (PEEK) base frame, which provides consistent circularity3, 4
- An industry-leading Effective Orifice Area (EOA) that may allow for greater blood flow that is supported by the clinical evidence of the Avalus valve 5,6
- A radiopaque coil for clear visibility for future valve-in-valve procedures 7,8
Additionally, the Avalus Ultra valve builds on 10 years of clinical experience and the long-term durability of the Avalus valve.9,10,11
“Patients with aortic stenosis are experiencing more complex disease, and therefore, procedures need to evolve to optimize their surgical care,” said Professor Pieter Kappetein, vice president and chief medical officer of the Cardiac Surgery, Structural Heart, and Mechanical Circulatory Support businesses in the Medtronic Cardiovascular portfolio. “Rooted in this evolving need, surgeons are demanding innovative technologies like the Avalus Ultra valve that is designed for increased ease of use and long-term durability to serve patients over their lifetime.”
What is aortic stenosis?
Aortic stenosis is a common heart problem typically caused by a narrowing of the heart’s aortic valve due to excessive calcium deposited on the valve leaflets. When the valve narrows, it does not open or close properly, making the heart work harder to pump blood throughout the body. Eventually, this causes the heart to weaken and function poorly, which may lead to heart failure and increased risk for sudden cardiac death.
A treatment for patients with aortic valve disease is surgical aortic valve replacement (SAVR). During this procedure, a surgeon will make an incision in the sternum to open the chest and expose the heart. The diseased native valve is then removed, and a new artificial valve inserted. Once in place, the device is sewn into the aorta and takes over the original valve’s function to enable oxygen-rich blood to flow efficiently out of the heart.
“Cardiac surgeons are looking to industry to partner with them to deliver improved innovation to treat their patients efficiently and effectively,” said Karim Bandali, Ph.D., president of the Cardiac Surgery business in the Medtronic Cardiovascular portfolio. “The Avalus Ultra valve builds on several successful innovation launches this year, including the acquisition and launch of the Penditure LAA Exclusion System. Aligned our Mission, Medtronic is committed to making the investments needed to advance and deliver innovative, lifesaving devices for better lifetime patient management.”
The Avalus Ultra valve received FDA approval in January 2024 and is currently only commercially available in the United States.
