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.

The Abbott MitraClip is the primary structural heart device used in transcatheter edge-to-edge repairs (TEER) of the mitral valve leaflets. The results of the COAPT trial dropped like a thunderclap Sunday at the Transcatheter Cardiovascular Therapeutics (TCT) annual meeting, with several cardiologists predicting the MitraClip device will have a swift and lasting impact on the treatment of heart failure patients.

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."
