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. 

New-onset AFib, linked to worse outcomes and higher healthcare costs, seen in 3.5% of TEER patients

Patients who developed new-onset AFib tended to be sicker than those who did not.

Intrepid transcatheter mitral valve pilot study shows positive 3-year outcomes

New data on the Medtronic Intrepid transcatheter mitral valve replacement system from the Intrepid Pilot Study and Intermediate-Term Outcomes of the Intrepid Early Feasibility Study, were presented at the 2022 Transcatheter Cardiovascular Therapeutics (TCT) conference.

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.

MitraClip and TriClip TEER devices continue to show positive results

Two late-breaking studies at the 2022 Transcatheter Cardiovascular Therapeutics (TCT) meeting provided positive data for Abbott's MitraClip transcatheter mitral valve repair (TMVR) device and the TriClip for transcatheter tricuspid valve repair (TTVR).

Comparison between transcatheter edge-to-edge repair (TEER) devices found Pascal was non-inferior compared with MitraClip in the CLASP IID pivotal trial.

he U.S. Food and Drug Administration (FDA) granted market clearance ion September 2022 for the Edwards Lifesciences Corp. Pascal Precision transcatheter valve repair system for transcatheter edge-to-edge repair (TEER). It is indicated for the treatment of patients with degenerative mitral regurgitation (DMR).

FDA clears Edwards Pascal device for transcatheter mitral valve repair

This is the second FDA-cleared transcatheter repair device for the mitral valve. Data from pivotal trial comparing Pascal vs. MitraClip will be presented at TCT 2022.

HFpEF patients with MR may face a higher mortality risk—but not if they have AFib

There is an established connection between MR and HFrEF, but we know much less about the link between MR and HFpEF. 

Three transcatheter tricuspid valve repair and replacement (TTVR) technologies that will likely see FDA clearance in. the next couple years include the Edwards Evoque transcatheter tricuspid valve (top left), Abbott TriClip (below) and the Edwards Lifesciences Pascal clip device (right).

Tricuspid valve therapies moving ahead of mitral therapies seeking market approval

The complexity of the mitral valve has slowed development of new transcatheter technologies, and it now seems much more likely that transcatheter devices for tricuspid valve will push ahead to gain FDA clearances.
