BACKGROUND Functional tricuspid regurgitation (FTR) is frequent in patients with mitral valve disease. Untreated tricuspid regurgitation (TR) may cause poor clinical outcomes. The surgical factors involved in annuloplasty for FTR remain controversial. Our objective was to compare effectiveness of different tricuspid annuloplasty (TVP), and reveal the risk factors of recurrence. METHODS We ana...

The basic surgical paradigm for mitral annuloplasty involves placing an undersized ring that encircles the entire mitral valve and uses the force of ring to compress the mitral annulus and leaflets along the septal to lateral axis (Fig. 1B). This septal-lateral compression is sometimes called septal lateral annular cinching (SLAC) [1,2]. Percutaneous adaptations of this procedure have used the ...

BACKGROUND Patients who undergo ring annuloplasty for ischemic mitral regurgitation (MR) often have persistent or recurrent MR. This may relate to persistent leaflet tethering from left ventricle (LV) dilatation that is not relieved by ring annuloplasty. Therefore, the purpose of this study was to test the hypothesis that recurrent MR in patients after ring annuloplasty relates to continued LV ...

Uncorrected chronic ischemic mitral regurgitation (CIMR) is associated with decreased left ventricular (LV) torsion and may contribute to a vicious cycle wherein “MR begets MR.” It has not been definitively established, however, whether the reduced LV torsion in CIMR is a direct result of the infarct, the MR, or a combination of the two. Currently, the most common technique to restore valve com...

BACKGROUND Ring annuloplasty, the standard treatment for ischemic mitral regurgitation (IMR), abolishes normal annular dynamics and freezes the posterior leaflet. We examined the impact of Paneth suture annuloplasty during acute IMR on motion of the mitral annulus and leaflets in an ovine model. METHODS AND RESULTS Eight sheep had radiopaque markers placed on the left ventricle, anterior mitr...

Mitral valve prolapse (MVP) is the most common cause of primary mitral regurgitation (MR), which represents leaflet or chordae elongation and is frequently accompanied by ruptured chordae. In almost all patients with this entity, annular dilatation is a common lesion. It is well known that the normal annulus has a unique saddle shape, but the saddle is flattened in MVP, and its dynamic characte...

The aim of this study was to analyze the effects about the use of a new completely flexible ring for mitral valve anuloplasty, the "Rama-Valvuloplasty-ring", in 182 patients operated on in the Pitié-Salpétrière Hospital, Paris, France for mitral valve regurgitation (MVR). From January 1998 to December 2003, 182 patients with mitral regurgitation (MR) underwent mitral reconstructive surgery at o...
