The Use of Transcatheter Devices for Mitral Repair and Replacement.

: Recent advances in device design have resulted in a wide variety of transcatheter treatment options for patients with symptomatic mitral valve disease. Surgery remains the gold standard for patients with symptomatic, primary mitral regurgitation, while transcatheter devices can be considered in higher-risk patients. For secondary mitral regurgitation, optimal medical therapy and cardiac resynchronization are recommended. Recent evidence suggests that transcatheter alternatives may be considered as well. This review will provide an overview of current transcatheter mitral repair and replacement technologies. These include those that mimic open surgical procedures such as edge-to-edge repair, choral replacement, direct annuloplasty, and valve replacement.
