Mitral Valve Repair for Mitral Valve Regurgitation with Papillary Muscle Displacement and Posterior Leaflet Prolapse
A case of abnormal chordae of the mitral valve (MV) associated with systolic anterior motion (SAM) is not commonly encountered in clinical practice. Here we report MV repair via the edge-to-edge technique in a 56-year-old male with MV regurgitation associated with papillary muscle displacement and posterior leaflet prolapse. Echocardiography revealed obstruction of the left ventricular outflow ...
متن کاملSevere Mitral Valve Prolapse with Flail Posterior Leaflet and Severe Mitral Regurgitation
Mitral valve prolapse (MVP) is defined as posterior displacement of all or part of MV leaflet(s) beyond MV annulus at least 2 mm into the left atrium (LA) during systole, with or without mitral leaflet thickening, but prolapsed leaflet(s) pointing towards apex in systole [1]. Mitral regurgitation (MR) is a common complication of MVP. Moreover, MVP with flail leaflet(s) is a severe form of MVP w...
متن کاملPosterior ventricular anchoring neochordal repair of degenerative mitral regurgitation efficiently remodels and repositions posterior leaflet prolapse.
OBJECTIVES Mitral valve repair techniques for degenerative disease typically entail leaflet resection or neochordal construction, which may require extensive resection, leaflet detachment/reattachment, reliance on diseased native chords or precise neochordal measuring. Occasionally, impaired leaflet mobility, reduced coaptation surface and systolic anterior motion (SAM) may result. We describe ...
متن کاملPreoperative posterior leaflet angle accurately predicts outcome after restrictive mitral valve annuloplasty for ischemic mitral regurgitation.
BACKGROUND Ischemic mitral regurgitation (MR) often persists after restrictive mitral valve annuloplasty, in which case it is associated with worse clinical outcomes. The goal of the present study was to determine whether persistence of MR and/or clinical outcome could be predicted from preoperative analysis of mitral valve configuration. METHODS AND RESULTS In 51 consecutive patients undergo...
متن کاملPosterior leaflet augmentation improves leaflet tethering in repair of ischemic mitral regurgitation.
OBJECTIVES Ischemic mitral regurgitation results from annular dilatation, leaflet tethering and leaflet flattening. Undersized annuloplasty corrects annular dilatation but worsens leaflet tethering and flattening. This exacerbation of abnormal leaflet geometry may contribute to poor repair results for ischemic mitral regurgitation (IMR). Using a sheep model of IMR, we hypothesized that posterio...
