Abbott already has an FDA-approved self-expanding TAVR valve, the Navitor system, on the market. The company is now evaluating the safety and effectiveness of a new balloon-expandable device that could potentially be implanted using software guidance. 

The Sapien 3 Ultra Resilia TAVR valve from Edwards Lifesciences is associated with a significantly higher survival rate after one year than the company's previous balloon-expandable valves. Researchers identified other key benefits as well, sharing their findings in JACC: Cardiovascular Interventions.

TAVR is a go-to treatment for symptomatic severe aortic stenosis in much of the world, thanks in large part to the hard work of research teams that never stop looking for new, innovative ways to make the technology more effective.

TAVR procedures have surged more than 30% since 2020, with more than 107,000 patients receiving a new prosthetic valve in 2023 alone. As this trend continues, it’s increasingly important that cardiologists consider the long-term impact on future coronary interventions patients may need.  

Self-expanding and balloon-expandable TAVR valves are associated with comparable success rates and one-year outcomes when treating type 1 bicuspid aortic stenosis. However, each valve type comes with its own advantages and disadvantages.

Medtronic has launched new research into AI's potential to identify patients with severe aortic stenosis and other worrying symptoms. The company hopes to overcome longstanding health disparities and reach individuals who may otherwise go untreated.

TAVR patients in this study were treated with early-generation devices that have since been updated, but researchers still believe their data are relevant to today's care teams.

The new data, presented during AHA Scientific Sessions 2024, suggest LAAC with Boston Scientific's Watchman FLX could be a safe, effective alternative to OAC for limiting post-ablation strokes.
