Transcatheter Repair of Mitral Regurgitation: Edwards Cardioband
The Cardioband is a device designed to perform direct percutaneous transfemoral annuloplasty by means of a half ring implanted on the posterior annulus, with beating heart, and under fluoroscopic and transesophageal echocardiography (TEE) guidance. The device is fixed in situ thanks to a series of helical anchors and is equipped with a system that allows adjustment of the degree of annular reduction to achieve a good result in terms of residual mitral regurgitation, without creating stenosis.
The procedure is associated with a much lower risk of mortality compared with surgical annuloplasty and is therefore reserved for patients who are not candidates for cardiac surgery due to the high risk of intra- and postoperative mortality.
The Cardioband can be employed to correct functional mitral regurgitation secondary to dilation of the left ventricular cavity and subsequent anatomical distortion of the entire valvular apparatus constituting the mitral valve.
