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 کامل132 Mitral Valve Replacement Versus Mitral Valve Repair
Background Standard mitral valve replacement (MVR) in patients with chronic mitral regurgitation results in consistent reductions in resting postoperative ejection fraction. This has been attributed to removal of the low-impedance ejection pathway into the left atrium or to disruption of the chordal apparatus. Mitral valve repair (MVP) does not reduce ejection fraction at rest. However, whether...
متن کاملLong-term outcomes after surgery for rheumatic mitral valve disease: valve repair versus mechanical valve replacement.
OBJECTIVES Although mitral valve (MV) repair is known to be superior to replacement in overall clinical outcomes, the appropriateness of valve repair for rheumatic MV disease remains controversial because of the risks of recurrent mitral dysfunction and the need for re-operation. METHODS From 1997 to 2007, 540 patients underwent either isolated MV repair (n=122) or replacement with a mechanic...
متن کاملMitral-valve repair versus replacement for severe ischemic mitral regurgitation.
BACKGROUND Ischemic mitral regurgitation is associated with a substantial risk of death. Practice guidelines recommend surgery for patients with a severe form of this condition but acknowledge that the supporting evidence for repair or replacement is limited. METHODS We randomly assigned 251 patients with severe ischemic mitral regurgitation to undergo either mitral-valve repair or chordal-sp...
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...
