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.

One of the cardiologists involved in the procedures said they represent "a significant leap forward in structural heart intervention."

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.

Adam Greenbaum, MD, explains how transcatheter electrosurgery can be used to prevent left ventricular outflow tract (LVOT) obstruction using a new procedure called Septal Scoring Along the Midline Endocardium (SESAME).

Radiation exposure during structural heart procedures much higher for echocardiographers than cardiologists

The new analysis focused on transcatheter edge-to-edge repair and left atrial appendage occlusion procedures.

Charles Davidson, MD, clinical chief of cardiology and medical director of the Bluhm Cardiovascular Institute, Northwestern University, explains what hospitals need to consider when starting a new structural heart program.

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.

'Promising' new data on TMVr among cancer patients

The study's authors examined data from nearly 23,000 patients who underwent transcatheter mitral valve repair from 2014 to 2018.

Mitral annulus calcification more than doubles a patient’s risk of heart valve disease

"For clinicians, suspicion for valve diseases should be increased and evaluations carefully performed for patients with MAC," according to one Mayo Clinic cardiologist.

Self-expanding heart valves and the presence of significant PVL were both linked to a heightened risk of mitral valve infective endocarditis after TAVR.
