The influence of saddle-shaped annuloplasty on leaflet curvature in patients with ischaemic mitral regurgitation.
OBJECTIVES Reports indicate that repair procedures for ischaemic mitral regurgitation (IMR) are less durable than previously thought. Repair failure has been shown to be stress related. Leaflet curvature is the major determinant of valve stress. Theoretical and animal experiments have shown that saddle-shaped annuloplasty optimizes leaflet curvature when compared with standard flat ring annulop...
متن کاملPercutaneous leaflet repair and annuloplasty for mitral regurgitation.
Percutaneous therapy for the treatment of mitral regurgitation has emerged rapidly over the past few years. Most of the percutaneous approaches are modifications of existing surgical approaches to mitral annuloplasty or leaflet repair. Catheter-based devices mimic these surgical approaches with less procedural morbidity and mortality as a consequence of their less invasive nature. Percutaneous ...
متن کاملLifting posterior mitral annuloplasty for enhancing leaflet coaptation in mitral valve repair: midterm outcomes.
BACKGROUND We evaluated the midterm outcomes of lifting posterior mitral annuloplasty for enhancing leaflet coaptation in mitral valve repair. METHODS Between October 2007 and December 2012, 341 consecutive patients with significant mitral regurgitation underwent lifting posterior mitral annuloplasty using a specially designed fabric annuloplasty strip that lifts the middle portion of the pos...
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...
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...
