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.

Earlier interventions may boost survival when TAVR patients experience a stroke

New research in JACC: Cardiovascular Interventions suggests improved collaborations between cardiologists and neurologists could help TAVR patients live longer after a periprocedural stroke.

Regulatory Roundup: FDA clears AI model for RV/LV ratios, approves calcium-blocking TAVR valve and much more

Read our review of some of the biggest FDA-related stories that have hit cardiology in the last month, including news from Viz.ai, Edwards Lifesciences, Abiomed and Medtronic. 

Medtronic launches Evolut FX TAVR system aortic stenosis

Medtronic launches Evolut FX TAVR system for severe aortic stenosis

This is the fourth device in Medtronic's Evolut TAVR platform. The self-expanding valve gained FDA approval in 2021 for the treatment of high- and low-risk patients presenting with symptomatic severe aortic stenosis.

Sentinel Boston Scientific PROTECTED TAVR stroke disabling stroke

TAVR embolic protection devices fail to reduce stroke risk, but some cardiologists—and a leading vendor—remain encouraged

The PROTECTED TAVR results presented at TCT 2022 resulted in a mix of reactions. For some cardiologists, the slight reduction in the risk of a disabling stroke after TAVR is a positive result. For others, it was simply not enough. 

Examples of structural heart transcatheter valve replacement procedure planning CT scans and post procedure followup for TMVR and TAVR.

VIDEO: CT imaging for TAVR and TMVR structural heart interventions

Joao Cavalcante, MD, director, cardiac MRI and structural CT labs, Minneapolis Heart Institute, discusses the use of cardiac CT imaging to plan and guide structural heart procedures.

TCT 2022 late-breaking clinical presentations announced

The Cardiovascular Research Foundation (CRF) announced the 32 late-breaking studies being presented at the Transcatheter Cardiovascular Therapeutics 2022 annual meeting at in Boston, Sept. 16-19.

DOACs after TAVR may put some patients at risk, new meta-analysis suggests

The new study, based on data from nearly 3,000 patients, compared DOACs such as rivaroxaban, apixaban and edoxaban with single and dual antiplatelet therapy. 

SAVR after TAVR is rare, but linked to a high mortality risk

Researchers tracked data from more than 2,000 patients, noting that surgical bailout, infective endocarditis and paravalvular leak were the most common reasons for surgery to be required after TAVR. The full study was published in the American Journal of Cardiology.
