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 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 کاملChordae replacement versus leaflet resection in minimally invasive mitral valve repair.
For many years, the quadrangular resection technique first proposed by Carpentier has become the gold standard for repair of posterior leaflet prolapse of the mitral valve (MV). Although this "resection" technique and its modifications are safe and very effective, they do not respect the anatomy of the MV and the physiological role of the posterior leaflet. Therefore some new techniques, aiming...
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 کاملHaircut mitral valve repair: posterior leaflet-plasty.
A 63-year-old man presented with symptomatic severe mitral regurgitat ion. Both trans-esophageal 3-D echocardiography and operative linear measurements showed a 25 mm long A2 anterior leaflet with a very wide (23 mm) prolapsing 30 mm long P2 posterior mid-scallop (Figure 1A,B). P1 and P3 were diminutive in height and width (Figure 2). A ‘haircut’ posterior leaflet-plasty was done to maintain le...
