Mitral Valve

The heart's mitral valve is the site of the most surgical valve repairs and valve replacements. After the resounding success of transcatheter aortic valve replacement (TAVR), which now makes up more than 50% of aortic valve replacements, there is wide expectation transcatheter mitral replacements will follow in the next few year. Currently, the most common transcatheter mitral procedure is transcatheter edge-to-edge (TEER) , using the MitraClip or Pascal clip devices. These devices are also being used for transcatheter tricuspid valve repair (TTVR). Other transcatheter mitral repair systems are in trials for minimally invasive annuloplasty and chordae tendineae repair.

TMVR vs. mitral valve surgery: Tendyne linked to improved survival in elderly patients
New data out of Germany suggest TMVR can offer intermediate-risk patients a safe alternative to surgery.
Data registries have been a huge success for U.S. structural heart programs
ACC/STS National Cardiovascular Data Registry metrics reporting for TAVR is important for marketing and care quality, explains Patricia Keegan, NP, with the Emory Heart and Vascular Center.

Paravalvular leak remains a significant problem after TAVR, SAVR and even TMVR. Could a new-look interventional technique help heart teams overcome this issue and improve patient outcomes?
Preventing blood clots after TMVR—what is the best anticoagulant for the job?
Choosing between DOACs and VKAs could make a significant impact on patient outcomes, according to new findings published in the Journal of the American College of Cardiology.
TAVR after mitral valve replacement linked to positive outcomes, but heart teams must plan ahead
Researchers in India performed TAVR on two relatively young patients with a preexisting mechanical mitral valve, sharing their experience in a new case report. The group highlighted the importance of planning ahead.

What does radiology have to do with climate change?

Kate Hanneman, MD, explains why many vendors and hospitals want to lower radiology's impact on the environment. "Taking steps to reduce the carbon footprint in healthcare isn’t just an opportunity," she said. "It’s also a responsibility."
