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.

An international team of researchers, led by specialists from Cleveland Clinic, found that DAPT was consistently linked to a greater risk of major or life-threatening bleeding events. 

TAVR has attracted many more patients to seek treatment for aortic valve disease, which has also helped feed more patients into surgical programs, despite TAVR now making up 84% of aortic valve replacement procedures.

A decade ago, when TAVR was first cleared by the FDA, surgeons had concern about losing business. But unexpectedly, TAVR has helped also gain heart surgery cases.

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.

Mitral annular calcium (MAC) does not appear to have a negative effect on long-term transcatheter aortic valve replacement (TAVR) outcomes, according to new research published in the American Journal of Cardiology.

Researchers from Cleveland Clinic reviewed data from more than 400 patients, presenting their findings in the American Journal of Cardiology.

Performing valve-in-valve transcatheter mitral valve replacement (ViV TMVR) with conscious sedation (CS) or monitored anesthesia care (MAC) instead of general anesthesia (GA) is safe and effective, according to new research published in JACC: Cardiovascular Interventions.

During valve-in-valve TMVR, patients are treated with conscious sedation or monitored anesthesia care instead of general anesthesia. This new analysis confirms that the change does not impact patient outcomes, but it was linked to a shorter length of stay.

Treating subclinical leaflet thrombosis after TAVR has been an ongoing challenge for structural heart clinicians, but recent research has gone a long way toward improving our understanding of this important topic.

In-hospital mortality was especially high among TAVR patients presenting with hypertrophic cardiomyopathy, according to a new analysis.

However, the study’s authors did find associations between suboptimal TAVR procedures and adverse outcomes.

The study, published in the American Journal of Cardiology, included data from more than 900 TAVR patients. Overall morality was 22.7% among patients with AFib and 14.4% among patients without AFib.

TAVR patients with gastrointestinal bleeding (GIB) were linked to longer lengths of stay and a higher risk of acute kidney injury than patients without GIB.
