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.

VIDEO: Transcatheter tricuspid devices likely to gain FDA clearance before new mitral advances

It was clear at TVT that tricuspid valve therapies will likely move ahead of new mitral therapies coming to market. Azeem Latib, MD, explained why.

Transcatheter mitral valve repair (TMVr) is associated with “promising” short-term outcomes among patients with a history of cancer, according to new research published in the American Journal of Cardiology. #TEER #TMVR

'Promising' new data on TMVr among cancer patients

The study's authors examined data from nearly 23,000 patients who underwent transcatheter mitral valve repair from 2014 to 2018.

Mitral annulus calcification more than doubles a patient’s risk of heart valve disease

"For clinicians, suspicion for valve diseases should be increased and evaluations carefully performed for patients with MAC," according to one Mayo Clinic cardiologist.

The latest data on mitral valve infective endocarditis after TAVR

Self-expanding heart valves and the presence of significant PVL were both linked to a heightened risk of mitral valve infective endocarditis after TAVR.

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."
