Percutaneous Tricuspid Valve Repair: The Triclip.

Tricuspid regurgitation is an often overlooked, but severe cardiac valvular disease associated with significant morbidity and poor quality of life. Tricuspid valve surgery is the only treatment that prevents progression of the disease but is often complicated or made impossible by perioperative risk factors. Due to the high-risk nature, tricuspid valve surgery is typically only done for severe tricuspid regurgitation at the time of left heart surgery, leaving many patients untreated. Medical therapy is limited primarily to diuretic agents, which are often unsuccessful in alleviating symptoms. Treatment of tricuspid regurgitation with transcatheter edge-to-edge repair has emerged after the success of this technique in mitral valve pathologies. This percutaneous procedure parallels surgical principles previously used for valve repair but eliminates the need for cardiac surgery, thus having the potential to serve as an alternative treatment in high-risk patients. The TriClip (Abbott Labs) device is an example of this therapy and the subject of this review.
