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 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 کاملLong-term assessment of mitral valve reconstruction with resection of the leaflets: triangular and quadrangular resection.
BACKGROUND The procedure of quadrangular resection and suture for prolapsed posterior leaflet of the mitral valve is a reliable and reproducible method that achieves excellent long-term results. However, triangular resection and suture of a prolapsed anterior leaflet is not widely supported and different techniques have been advocated. The aim of this study was to review our experience of mitra...
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...
