Mitral stenosis (MS) after mitral valve (MV) repair is a slowly progressive condition, usually detected many years after the index MV surgery. It is defined as a mean transmitral pressure gradient (TMPG) >5 mmHg or a mitral valve area (MVA) <1.5 cm(2). Pannus formation around the mitral annulus or extending to the mitral leaflets is suggested as the main mechanism for developing delayed MS afte...

To assess the efficacy of the trans-septal approach to the mitral valve, 40 patients who underwent mitral valve surgery via this approach were compared to 37 patients who underwent surgery via the standard left atriotomy. Concomitant procedures included tricuspid annuloplasty, aortic valve replacement, closure of atrial septal defect, coronary artery bypass grafting and aortic valve repair. The...

doi:10.1016/j.jtcvs.2007.10.060 D espite the widely held consensus that valve repair is the preferred surgical treatment for patients suffering from degenerative mitral valve disease, valve replacement for this condition remains all too prevalent. In the past few years interest in mitral valve repair has expanded among cardiologists and surgeons, with the recognition that asymptomatic patients ...

OBJECTIVE Mitral valve repair in rheumatic patients is still a challenge. The purpose of this study is to analyze the results of mitral valve repair in rheumatic patients in the Heart Institute University of Sao Paulo Medical School. METHODS Were analyzed retrospectively, between 1985 and 2005, 330 patients submitted to mitral valve repair in the Heart Institute of São Paulo. The mean age was...

BACKGROUND To investigate the association between the coaptation height of mitral valve and mitral regurgitation after mitral valve repair. METHODS From Sep 2014 to Jun 2015, 20 patients underwent mitral valve valvuloplasty for mitral regurgitation were included. Ring annuloplasty was performed in all cases. Mitral valve short-axis dimension (MVd), coaptation height (CH), Left ventricular eje...

We report the case of a patient with situs inversus totalis, annuloaortic ectasia complicated by aortic insufficiency and mitral regurgitation which induced congestive heart failure. Both valvular lesions were repaired physiologically using aortic root sparing Yacoub 'remodeling' technique and mitral ring annuloplasty. Valve sparing techniques can be used effectively even in patients with compl...

after multidisciplinary evaluation, 3 high-risk patients underwent transfemoral tricuspid valve-in-ring implantation (TVIRI) for refractory congestive heart failure because of deterioration of their tricuspid surgery, using Sapien XT valves (Edwards Lifesciences Inc, Irvine, CA). Patient 1: 44-year-old man, drug abuse, 4 episodes of tricus-pid endocarditis, 2 previous cardiac surgeries for mitr...

The article by deVarennes et al in the current issue of Circulation details the outcomes in 44 patients with severe (4 ) Carpentier type IIIb ischemic mitral regurgitation undergoing mitral valve repair consisting of posterior leaflet extension with bovine pericardium, coupled with remodeling annuloplasty, with or without coronary revascularization.1 Dissatisfied with the long-term results of a...

OBJECTIVE To introduce a new concept in the annuloplasty technology. Although rigid and flexible rings meet the basic needs of adults, they do not preserve the changes in shape and size occurring during the cardiac cycle. If implanted in children, such materials do not allow growth of the native annulus. METHODS From March 2003 to March 2007, 207 patients underwent mitral and/or tricuspid val...

Since the introduction of the annuloplasty ring, many attempts have been made to obtain a flexible ring that preserves the physiological motion of the mitral annulus. We experimented with a new technique using autologous pericardium to construct a more flexible ring. Twenty patients underwent mitral valve repair for degenerative disease and were treated by a posterior pericardial annuloplasty a...
