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.

Risk score predicts outcomes for heart failure patients undergoing TEER

The new analysis included data from nearly 700 patients who underwent TEER, formerly known as TMVR, over an eight-year period.

Surgery still more common than TMVR among AMI patients, but the gap is shrinking

The study's authors emphasized how important it is for clinicians to work together to determine the best treatment strategy.

Significant MR after TAVR linked to higher mortality rates—but staged interventions may help

Percutaneous edge-to-edge mitral valve repair was associated with improved outcomes among TAVR patients with persistent mitral regurgitation.

When TEER fails, most patients require mitral valve replacement

The team's findings were presented at the 101st Annual Meeting of the American Association for Thoracic Surgery and published in the Journal of the American College of Cardiology.
