TAVR

Transcatheter aortic valve replacement (TAVR) is a key structural heart procedure that has rapidly expanded in the decade since it was first FDA cleared. TAVR has come a paradigm shift in how many aortic stenosis patients are treated, now making up more than 50% of U.S. aortic valve replacements. It is less invasive than open heart surgery and recovery times are greatly reduced. TAVR can also be used in patients who otherwise are too high risk to undergo surgery. TAVR is referred to as transcatheter aortic valve implantation (TAVI) in many placed outside of the U.S. TAVR inspired the growing areas of transcatheter mitral repair or replacement and transcatheter tricuspid valve repair and replacement.

Medtronic TAVR valves at heart of key studies presented during PCR London Valves 2024

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.

Prosthesis-patient mismatch after TAVR: 5 key findings related to patients with small annuli

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.

First patients treated with Abbott’s new balloon-expandable TAVR valve

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.

Newest TAVR valve from Edwards linked to better 1-year outcomes than its predecessors

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.

How TAVR valve choice impacts outcomes when treating type 1 bicuspid AS

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 using AI to identify more TAVR patients in need

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.

SAVR linked to higher 10-year survival rate than TAVR for low-risk patients

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.

Redo TAVR: The impact of implanting balloon-expandable valves in failed self-expanding valves

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