Abstract

Mitral regurgitation (MR) is associated with poor prognosis and high incidence of clinical events if left untreated. To reduce the invasiveness of the surgical approach, different types of trans-catheter procedures are becoming available. The MitraClip procedure (Abbott Vascular Inc. Menlo Park, CA) is yet the only available at the moment. The procedure is used to treat high risk surgical candidates with either functional or degenerative MR. Recent trials have shown that the procedure is safer than surgery, although less effective. Efficacy of the procedure depends on several factors, including patient selection, anatomy of the valve and the experience of the operators. However, when treating high risk patients a suboptimal repair obtained with low risk can be a acceptable outcome. In the future, novel devices, improved knowledge, more efficient imaging and transcatheter mitral prosthetic valve implantation may expand the indications to those patients currently not treated by MitraClip for anatomical unsuitability, as well as may improve the results both in term of early efficacy and long term durability.
