BACKGROUND New insight into the 3D dynamic behavior of the mitral valve has prompted a reevaluation of annuloplasty ring designs. Force balance analysis indicates correlation between annulus forces and stresses in leaflets and chords. Improving this stress distribution can intuitively enhance the durability of mitral valve repair. We tested the hypothesis that saddle-shaped annuloplasty rings h...

BACKGROUND Mitral valve repair is preferred over prosthetic replacement. We surgically repaired mitral valve with degenerated sclerotic lesion and demonstrated mid-term results. METHODS Mitral valve plasty (MVP) was performed with several procedures including ring annuloplasty, leaflet slicing and decalcification. RESULTS There were 19 males and 19 females with a mean age of 67 ± 12 y.o (n ...

A 45-year-old female patient was admitted to our hospital with shortness of breath and swelling in the leg. Ten months prior to the admission she had undergone mitral valve replacement (31 St. Jude bioprosthesis) and tricuspid valve annuloplasty (33 Medtronic ring) because of carcinoid heart disease. All infective parameters were within the normal limits and no fever was detected. A two-dimensi...

INTRODUCTION We analysed retrospectively patients who underwent mitral valve repair using techniques beyond the "French correction", as popularised by Carpentier. METHODS From June 1997 to June 2006, 153 patients underwent mitral valve repair. Their mean age was 63.1 +/- 13.5 years (range 19-87). Mean Euroscore was 4.9 +/- 2.1 (2-13). Type II lesions were present in 109 cases. There were 123 ...

A 49-year-old male had mitral annuloplasty with a Cosgrove– Edwards band. Twelve months later he was asymptomatic, but transthoracic and transoesophageal echocardiograms showed dehiscence of the annuloplasty band. He underwent an uneventful mitral valve replacement. This case demonstrates the value of long-term echocardiographical follow-up of cardiac valvular prostheses irrespective of the pat...

OBJECTIVES The aim of this study was to examine 1-year outcomes of transseptal balloon-expandable transcatheter heart valve implantation in failed mitral bioprosthesis, ring annuloplasty, and mitral annular calcification (MAC). BACKGROUND Immediate outcomes following transseptal mitral valve implantation in failed bioprostheses are favorable, but data on subsequent outcomes are lacking. MET...

We describe a 73 year-old patient with mitral valve pericardial bioprosthesis Carpentier-Edwards 29M implanted due to the rheumatic mitral stenosis 21 years ago. Hemodynamic destabilisation had emerged 18 months before the admission. Echocardiography revealed significant bioprosthesis degeneration with calcification of its leaflets, small pannus on the bioprosthetic ring, moderate mitral stenos...

Background Mitral valve repair (MVR) shows clinical and economic superiority over mitral valve replacement in patients with dystrophic and rheumatic regurgitation, but outcomes are less certain in chronic ischemic mitral regurgitation (IMR). We hypothesize that MVR may have adverse effects on LV hemodynamics resulting from suboptimal annuloplasty geometry and post-repair mitral valve stenosis w...

The mitral valve complex is consisted of annulus, leaflets, chordae tendineae, papillary muscle (PMs) and surrounding left ventricle. Functional mitral regurgitation (MR) results from left ventricular remodeling such as dilatation or distortion, which displaces the PMs and then tethers the mitral leaflets, restricting leaflet coaptation. Undersized annuloplasty, which has been widely accepted a...

BACKGROUND Recurrent functional mitral regurgitation (MR) has been reported after mitral valve repair with annuloplasty in patients with dilated cardiomyopathy, but the mechanism is not understood completely. The authors sought to identify abnormalities of the mitral valve and left ventricle that are associated with recurrent MR after mitral annuloplasty. METHOD AND RESULTS In 104 patients wi...
