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.

When infective endocarditis after TAVR is most likely to be fatal

Researchers reviewed data from more than 900 patients, sharing their research in the American Journal of Cardiology.

How modified bioprosthetic heart valves could limit calcification, reduce need for TAVR

Bioprosthetic heart valves often express foreign sugars that trigger a response from the body's immune system. This immune response appears to be associated with calcification.

TAVR associated with lower healthcare costs than surgery

Researchers examined Medicare data from 2016 to 2018, presenting their findings in Circulation: Cardiovascular Interventions.

Seeking Out Severe Aortic Stenosis: The Low Down on Low Flow-Low Gradient

Sponsored by Medtronic

It’s not uncommon for severe aortic stenosis to go unrecognized, and thus untreated. When the data points to the existence of low-flow, low-gradient aortic stenosis, a diagnosis can be even more challenging.

Time of day does not affect TAVR or SAVR outcomes

One previous study had suggested outcomes may improve in the afternoon, but researchers did not find that to be the case. 

TAVR is safe and effective among asymptomatic patients, new research confirms

TAVR was associated with a consistently low risk of all-cause mortality or disabling stroke.
