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.

Cardiothoracic surgeons perform UCSF's first robotic mitral valve surgery. A 3D camera allows surgeons to see the mitral valve and other structures inside the heart. Surgeons use a robotic surgical system to guide the robotic arms and movements of the surgical instruments.

Surgeons praise mobility, precision of robotically assisted mitral valve procedure

“Robotically assisted mitral valve surgery allows us to make even smaller incisions with greater precision,” one surgeon said. “By using the robotic arms, we have more degrees of articulation than with our natural wrists."

Mitral and_tricuspid transcatheter valves Evoque and Intrepid were discussed at TVT 2022.

VIDEO: Transcatheter tricuspid devices likely to gain FDA clearance before new mitral advances

It was clear at TVT that tricuspid valve therapies will likely move ahead of new mitral therapies coming to market. Azeem Latib, MD, explained why.
