Transcatheter mitral valve repair using edge-to-edge repair is a minimally invasive, catheter-based procedure used to treat significant mitral regurgitation, a condition in which the mitral valve does not close properly, allowing blood to flow backward from the left ventricle into the left atrium. This technique, called mitral transcatheter edge-to-edge repair (mTEER), reduces leakage by bringing portions of the valve’s leaflets together. Unlike valve replacement, it preserves the patient’s native mitral valve rather than implanting a new prosthetic valve.

 

Careful patient selection is essential. This procedure may be appropriate for selected patients with symptomatic primary, or degenerative, mitral regurgitation who face prohibitive surgical risk. It is also used in certain patients with secondary, or functional, mitral regurgitation who remain symptomatic despite optimized heart failure treatment. The primary goals are to reduce mitral regurgitation, relieve symptoms such as shortness of breath and fatigue, and improve functional capacity and quality of life. In appropriately selected patients with heart failure and secondary mitral regurgitation, mTEER combined with ongoing medical therapy can also reduce heart failure hospitalizations. It does not replace the need for continued management of underlying heart disease.

​

Following treatment, patients receive individualized medication instructions, including antithrombotic therapy when appropriate, and ongoing cardiology follow-up. Echocardiographic assessment helps evaluate clip position, remaining regurgitation, and valve function. Continued clinical monitoring and cardiac rehabilitation when appropriate support recovery and long-term cardiovascular care.
