[Catheter based mitral valve repair for severe mitral regurgitation: patient selection].

The catheter-based mitral valve repair is a novel technology for the treatment of severe mitral regurgitation (MR). This technique is suitable for elderly patients with pronounced co-morbidities who are deemed to be high risk for conventional heart surgery. A meaningful reduction of mitral regurgitation leads to improvement of symptoms and quality of life. Studies also demonstrate reverse remodeling of the left ventricle. In heart failure patients with severe MR percutaneous repair reduces re-hospitalization rates>50% in comparison to optimal medical treatment. For degenerative MR conventional surgery is the gold standard, whereas for high surgical risk patients and for severe functional MR percutaneous repair is an alternative.
