The MitroFix prosthesis - a new way of mitral valve repair

Oertel F.

Abstract

In most cases of Mitral Valve Regurgitation (MVR) only the PML has a prolapse or restrictive alteration (fibrotic or ischemic). Secondary ring dilatation increase the MVR. Although many studies showed, that Mitral Valve Repair (MVR) should be possible in 80-90% of the patients, the truth is, that 30-40% of the diseased valves will be replaced. The cause of it is the sometimes very complex pathology of the mitral valve (MV) disease, especially if the underlying problem is a insufficient coaptation area of the posterior mitral leaflet (PML) with a so far normal anterior mitral leaflet (AML) due to severe restriction (ischemic, rheumatic), destruction (endocarditic) or hypoplasia of the PML. The repair of such diseased valves is very time-consuming, challenging and implies a great experience of the surgeon. Because of the increase of multimorbide patients with different organ function impairments and of combined surgical therapy cross clamp time and perfusion time has to be kept as short as possible to improve postop outcome. Therefore many MV are replaced.The MitroFix device could be a new concept for repair of MVR, especially if only the PML is involved. Using the MitroFix device, a partially replacement of the PML with a D-shaped annuloplasty ring imitating the PML in closed position, and leaving the AML in place offers a new additional possibility of MVRepair. The patient could leave the hospital with his own mitral valve.
