Mitral Valve Transcatheter Edge-to-Edge Repair

Transcatheter edge-to-edge mitral valve repair is a treatment option for patients with high or prohibitive risk for surgical repair of degenerative mitral regurgitation with suitable anatomy.

Under transesophageal echocardiographic (TEE) guidance the repair device is advanced across the mitral valve into the left ventricle and grasps the anterior and posterior leaflet of the mitral valve to approximate the leaflets at the location of the regurgitant jet. During the procedure, the deployment of more than 1 clip is often required to achieve an optimal reduction in mitral regurgitation.

These videos illustrate preprocedural TEE without (left) and with (right) color Doppler (A), and 3D TEE of mitral valve (B) showing severe mixed degenerative and functional mitral regurgitation.

During the procedure, fluoroscopy shows deployment and release of an edge-to-edge mitral valve repair device from the delivery system (C).

TEE with color Doppler after implant of 1 device in the medial aspect of the mitral valve demonstrates reduction of mild regurgitation from severe to mild (D).

After the procedure, a final 3D TEE demonstrates anterior and posterior mitral valve leaflets grasped by the edge-to-edge mitral valve repair device (E).
