Annuloplasty for valve repair with a new biodegradable ring: an experimental study.
BACKGROUND AND AIM OF THE STUDY The biodegradable ring was recently developed for mitral and tricuspid annuloplasty. The study aim was to assess the histological biocompatibility of the biodegradable ring and orifice area growth in a porcine model. METHODS The smallest (size 16) biodegradable ring was implanted into the tricuspid annulus of 16 juvenile pigs. All animals were followed up by tr...
متن کاملSafety and feasibility of a novel adjustable mitral annuloplasty ring: a multicentre European experience†
OBJECTIVES Recurrent mitral regurgitation is a significant problem after mitral valve repair in patients with functional valve disease. We report the safety and feasibility of a novel adjustable mitral annuloplasty device that permits downsizing of the anterior-posterior diameter late after initial surgery. METHODS In this multicentre, non-randomized, observational register, patients with mod...
متن کاملHomemade expanded-polytetrafluoroethylene flexible mitral annuloplasty ring.
A homemade mitral annular prosthesis has been developed using expanded-polytetrafluoroethylene material. It is safe in that it avoids the risk of prosthesis wrinkle when stitches are tied. Simultaneously, it is strong enough to prevent future stretching and rupture. This device has been implanted in 60 patients with good and stable results at 42 months of follow-up. Our flexible mitral annular ...
متن کاملTricuspid valve repair: is ring annuloplasty superior?
OBJECTIVES Tricuspid regurgitation (TR) secondary to left heart disease is the most common aetiology of tricuspid valve (TV) insufficiency. Valve annuloplasty is the primary treatment for TV insufficiency. Several studies have shown the superiority of annuloplasty with a prosthetic ring over other repair techniques. We reviewed our experience with different surgical techniques for the treatment...
متن کاملTransseptal implantation of a transcatheter heart valve in a mitral annuloplasty ring to treat mitral repair failure.
A 56-year-old woman was admitted for recurrent, refractory congestive heart failure. When she was aged 17 years, she had a Hodgkin lymphoma treated by chest radiation. She then developed postradiation heart disease, which required surgery in 2004, combining mitral valve repair using a Physio semirigid ring sized 28 mm (Edwards Lifesciences Inc; Irvine, CA) and tricuspid annuloplasty. In March 2...
