OBJECTIVES The study aimed to evaluate the feasibility of off-pump transapical mitral valve-in-ring implantation and to test the performance of a custom-made self-expandable stent valve, in comparison with the standard SAPIEN valve. METHODS Acute experiments were performed in five pigs. Animals (mean weight 58.4 ± 7.3 kg) underwent mitral valve annuloplasties under cardiopulmonary bypass usin...

We report a child with myocardial necrosis, dilated cardiomyopathy, and severe mitral valve (MV) regurgitation following neonatal enteroviral myocarditis. He underwent MV annuloplasty at 18 months and MV replacement at 3 years of age. He remains asymptomatic on medical therapy at 8 years of age. Mitral valve surgery may stabilize the evolution of dilated cardiomyopathy and delay the ultimate ne...

BACKGROUND Management of severe ischemic mitral regurgitation remains difficult with disappointing early and intermediate-term surgical results of valve repair. METHODS AND RESULTS Forty-four patients with severe (4+) Carpentier type IIIb ischemic mitral regurgitation underwent mitral valve repair, with or without surgical revascularization, by posterior leaflet extension with a patch of bovi...

Background Patients with end stage dilated cardiomyopathy exhibit extensive remodeling of the left ventricle, annular dilation, and significant mitral and tricuspid regurgitation. These changes increase perioperative morbidity and mortality, and emphasize patient candidacy for heart transplantation. We previously published that Reductive Annuloplasty of Double (mitral and tricuspid) Orifices co...

study because this is the technique that has been the most used in clinical practice for ventriculo-aortic junction reduction and stabilization. Of course, it has an effect on valve coaptation. It increased the coaptation by plications, or if you prefer, by closing the subcommissural triangle. This portion of the aortic root is just above what we considered to be the ventriculo-aortic junction,...

he appearance of functional mitral regurgitation (MR) predicts poor survival for patients with nonischemic dilated cardiomyopathy (DCM). Therefore, surgical treatment is recognized as crucial for improving life expectancy. Regarding mitral reconstruction in DCM, Bolling et al reported the clinical usefulness of the undersized mitral annuloplasty (MAP) in 1995;1 however, recurrent or persistent ...

Secondary mitral regurgitation (MR) is more frequent, portends a worse prognosis and its diagnostic and management are more difficult in comparison with primary MR. The mechanism of secondary MR is linked to the left ventricle remodeling, while the valve morphology is normal. Surgical treatment of severe secondary MR consists either in mitral valve replacement or in mitral valve repair. The mos...

From 1978 through 1987, 321 patients who had functional tricuspid regurgitation (TR) associated with mitral or combined mitral and aortic valve disease underwent tricuspid annuloplasty with our modification of the original De Vega's annuloplasty technique. The modified De Vega's annuloplasty consisted of two separate semicircular sutures placed around the anterior and lateral aspect of the tric...

BACKGROUND AND AIM OF THE STUDY The use of autologous pericardium for annuloplasty during mitral valve repair is a subject of controversy; hence, the study aim was to evaluate the authors' long-term results using this technique. METHODS A retrospective review was conducted of 173 consecutive patients (mean age 59.6 +/- 16.3 years; range: 19-92 years) who underwent mitral valve repair compleme...

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...
