One study presented during the three-day conference focused on the potential benefits of an optimized TAVR pathway. Another study, meanwhile, tracked changes in paravalvular leak severity over time.

PPM is still relatively common after TAVR, especially among patients with a small aortic annulus. What can be done to minimize the risk of PPM? Does valve type play a role? Researchers explored those questions, and many others.

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.

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.

Researchers took a closer look at the effectiveness of redo TAVR, implanting Sapien 3 valves into a variety of explanted CoreValve and Evolut valves.
