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.

Mitral valve repair vs. replacement: Surgeons track long-term outcomes in patients with infective endocarditis
Mitral valve repair was linked to a significant improvement in long-term survival when treating infective endocarditis. Some patients are not good candidates for a repair procedure, however, making replacement the best possible option.
Cardiologists make history, complete world’s first robotic transcatheter mitral valve replacements
One of the cardiologists involved in the procedures said they represent "a significant leap forward in structural heart intervention."
Surgeons make history, perform world’s first living mitral valve replacement
The historic heart procedure was part of a series of operations that saved the lives of three young girls. “The whole situation is extraordinary, whether you look at it from the standpoint of a scientific breakthrough or the average person’s point of view,” one parent said.
Key details on the use of ICE to guide structural heart procedures
Scott Lim, MD, details his experience using intracardiac echo to help guide structural heart procedures with or without traditional TEE. One key benefit of ICE, he explained, is its ability to overcome imaging challenges posed by prior cardiac surgeries.
Robotic mitral repair compares favorably to surgery—but some concerns remain
Robotic-assisted mitral valve repair is associated with short-term outcomes comparable to conventional surgery, according to a new analysis of more than 40,000 patients. Robotic treatment also helps patients spend less time in the hospital, but the costs are much higher.

Mitral valve prolapse during pregnancy linked to higher risk of cardiac complications

MVP also appears to increase the risk of certain problems during childbirth.

TEER associated with ‘important and significant’ reductions in hospitalization rates

Considering the study's high-risk patient population, researchers were especially impressed by these one-year outcomes.

CUTTING-EDGE findings shine new light on mitral valve surgery after failed TEER

Overall, mitral valve surgery after TEER was associated with a 30-day mortality rate of 16.6% and one-year mortality rate of 31.3%.

TEER benefits all HF patients with SMR, but men see more long-term benefits

The study's authors examined data from men and women who underwent TEER with the MitraClip device in addition to guideline-directed medical therapy.

Valve-in-valve TMVR an effective option for patients with mitral prosthesis dysfunction

Adjusted mortality and perioperative complications were both lower among patients undergoing ViV TMVR.

Survival rates similar when treating secondary MR with TEER or surgery

Surgical mitral valve repair, however, was also associated with multiple benefits.

TMVR outcomes suffer when patients have heart failure and diabetes—but benefits remain

Overall, the authors emphasized, TMVR helped heart failure patients with and without diabetes.

Next-day discharge after TMVR is on the rise

By 2018, nearly half of all TMVR patients were going home the very next day. Outcomes for these patients have been consistently positive.
