The US Food and Drug Administration (FDA) has approved the PASCAL precision transcatheter valve repair system from Edwards Lifesciences for the treatment of degenerative mitral regurgitation (DMR) patients.
The company has designed the system for transcatheter edge-to-edge repair (TEER) of the mitral valve.
TEER grasps the anterior and posterior mitral valve leaflets using a clipping device, which is similar to a treatment known as the Alfieri stitch that was developed in cardiac surgery.
