Outcomes of Mitral Valve Repair: Quadrangular Resection versus Chordal Replacement
BACKGROUND Mitral valve repair for posterior mitral leaflet (PML) prolapse has been considered to be a standard treatment because of its high success rate and high level of patient satisfaction. The aim of this study was to evaluate the clinical results of two different techniques of PML prolapse, quadrangular resection (QR) and chordal replacement (CR). MATERIALS AND METHODS The subjects con...
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 کاملMitral valve repair. Quadrangular resection of the posterior leaflet in patients with myxomatous degeneration.
OBJECTIVE To analyze the immediate and late results of mitral valve repair with quadrangular resection of the posterior leaflet without the use of a prosthetic ring annuloplasty. METHODS Using this technique, 118 patients with mitral valve prolapse who underwent mitral repair from January '84 through December '96 were studied. Age ranged from 30 to 86 (mean = 59.1 +/- 11.8) years and 62.7% we...
متن کاملPersonalized Computational Modeling of Mitral Valve Prolapse: Virtual Leaflet Resection
Posterior leaflet prolapse following chordal elongation or rupture is one of the primary valvular diseases in patients with degenerative mitral valves (MVs). Quadrangular resection followed by ring annuloplasty is a reliable and reproducible surgical repair technique for treatment of posterior leaflet prolapse. Virtual MV repair simulation of leaflet resection in association with patient-specif...
متن کاملThe new butterfly technique-a sophisticated repair method for posterior leaflet prolapse.
Mitral valve repair is currently considered the standard treatment for mitral regurgitation. Posterior leaflet prolapse has been treated by quadrangular resection and ring annuloplasty for many years. Although it is a classic and reproducible method, this technique may predispose to systolic anterior motion (SAM) of the anterior leaflet of the mitral valve. The incidence of SAM has been reporte...
