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 کاملLeaflet-to-Annuloplasty Ring Clipping for Severe Mitral Regurgitation.
A n 86-year-old man presented with recurrent heart failure and severe mitral regurgitation in the setting of previous surgical mitral repair for degenerative valve disease. Surgery had consisted of placement of a 32-mm CarpentierEdwards Physio II annuloplasty ring (Edwards Lifesciences, Irvine, California). Transesophageal echocardiography demonstrated a large anterior leaflet (Figure 1A, arrow...
متن کاملMechanism of persistent ischemic mitral regurgitation after annuloplasty: importance of augmented posterior mitral leaflet tethering.
BACKGROUND We hypothesized that surgical annuloplasty for ischemic mitral regurgitation (MR) that displaces the posterior annulus anteriorly can potentially augment posterior leaflet (PML) tethering, leading to persistent MR. Relationships between leaflet configurations and persistent ischemic MR after the annuloplasty were investigated. METHODS AND RESULTS In 31 patients with surgical annulo...
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...
