BACKGROUND The efficacies of tricuspid valve repair, risk factors for treatment failure and postoperative quality of life have not been thoroughly evaluated in patients with tricuspid insufficiency associated with rheumatic heart disease (RHD). We therefore reviewed our experience with ring and non-ring tricuspid annuloplasty for the treatment of functional tricuspid insufficiency (TI) in RHD. ...

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...

The implantation of annuloplasty rings is a common surgical treatment targeted to re-establish mitral valve competence in patients with mitral regurgitation. It is hypothesized that annuloplasty ring implantation influences leaflet curvature, which in turn may considerably impair repair durability. This research is driven by the vision to design repair devices that optimize leaflet curvature to...

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...

BACKGROUND To allow performance of "stand-alone" mitral annuloplasty with minimal invasiveness, percutaneous techniques consisting of delivery into the coronary sinus (CS) of devices intended to shrink the mitral valve annulus have recently been tested in animal models. These techniques exploit the anatomic proximity of the CS and mitral valve annulus in ovine or dogs. Knowledge of a detailed a...

AIMS To evaluate the feasibility of papillary muscle shortening in a specific group of high risk patients with ischaemic mitral regurgitation undergoing mitral valve reconstruction. BACKGROUND From January 1996 to December 1997, 712 (10.1%) out of a total of 7042 open heart patients underwent mitral valve surgery in our hospital. Mitral valve reconstruction was performed in 408 of these patie...

BACKGROUND Although surgical annuloplasty is the standard repair for ischemic mitral regurgitation (IMR), its application is limited by high morbidity and mortality. Using 2D and real-time 3D echocardiography in an ovine model of chronic IMR, we evaluated the geometric impact and short-term efficacy of a percutaneous transvenous catheter-based approach for mitral valve (MV) repair using a novel...

BACKGROUND Closed and open annuloplasty rings are both used for mitral valve repair. This study compared the clinical and echocardiographic results in patients with degenerative mitral disease undergoing MV repair with closed semirigid rings vs open bands. METHODS Between 2004 and 2008, 377 patients (mean age, 59 + or - 12 years) underwent mitral valve repair. Valve pathology was degenerative...

Systolic anterior motion of the mitral valve is an uncommon complication of mitral valve repair, which requires immediate supplementary surgical action. Edge-to-edge suture is considered as an effective technique to treat post-mitral valve repair systolic anterior motion by clinical researchers. However, the fundamentals and quantitative analysis are vacant to validate the effectiveness of the ...

Objective: Patients with end stage ischemic dilated cardiomyopathy (IsDCM) exhibit extensive remodeling of the left ventricle, and significant mitral tricuspid regurgitation. We investigated if implantation artificial valve preservation native could be used as a method combined annuloplasty complete myocardial revascularization in IsDCM.
