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.

Medtronic using AI to identify more TAVR patients in need

Medtronic has launched new research into AI's potential to identify patients with severe aortic stenosis and other worrying symptoms. The company hopes to overcome longstanding health disparities and reach individuals who may otherwise go untreated.

How robotic-assisted mitral valve repair compares to conventional surgery

Costs remain a concern, especially for low-volume centers, but robotic-assisted MV repair is associated with short-term outcomes comparable to more conventional techniques. 

LAMPOON before TMVR improves symptoms without complications, long-term data confirm

LVOT obstruction remains a significant complication of TMVR, making the long-term safety and effectiveness of the LAMPOON technique a hot topic in interventional cardiology.

Baseline TR linked to lower quality of life after TAVR, M-TEER—are more interventions the answer?

Patients presenting for TAVR or M-TEER with baseline moderate or severe tricuspid regurgitation were associated with lower post-treatment KCCQ scores and a higher mortality rate. Perhaps treating more of these patients with tricuspid valve repair or replacement could make a difference, researchers noted. 

Treating atrial functional mitral regurgitation (AFMR) with surgery may be more beneficial than medical therapy alone, according to new data published in JAMA Network Open.[1]

Atrial functional mitral regurgitation: Surgery improves outcomes more than medical therapy alone

"These findings underscore the importance of understanding AFMR and its treatment options," one cardiologist said.

Treating mitral regurgitation with transcatheter mitral edge-to-edge repair (TEER) using the MitraClip device is associated with a low risk of cerebrovascular accidents (CVAs) such as stroke and transient ischemic attack (TIA), according to new data published in The American Journal of Cardiology.[1]

TEER with Abbott’s MitraClip linked to low stroke risk, new study confirms

Treating severe MR with the popular device does not appear to increase a patient's risk of stroke or transient ischemic attack. When patients present with AFib, however, care teams may want to make certain adjustments to optimize outcomes.

Echocardiography vs CT for Prediction of Newly Created LVOT Area during TMVR

3D echo comparable to CT for predicting TMVR complications

LVOT obstruction after TMVR remains a significant concern among structural heart cardiologists. Predicting the risk of LVOT obstruction typically requires CT, which comes with certain disadvantages compared to other imaging options.
