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 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.

The latest data on mitral valve infective endocarditis after TAVR

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

VIDEO: MitraClip vs. surgical mitral valve replacement

Joanna Chikwe, MD, founding chair of the department of cardiac surgery at Cedars-Sinai Hospital, compares transcatheter edge-to-edge repair (TEER) to mitral valve surgery for primary mitral regurgitation.

The Abbott MitraClip is the primary structural heart device used in transcatheter edge-to-edge repairs (TEER) of the mitral valve leaflets. The results of the COAPT trial dropped like a thunderclap Sunday at the Transcatheter Cardiovascular Therapeutics (TCT) annual meeting, with several cardiologists predicting the MitraClip device will have a swift and lasting impact on the treatment of heart failure patients.
