Homemade 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 کاملHow Local Annular Force and Collagen Density Govern Mitral Annuloplasty Ring Dehiscence Risk.
BACKGROUND Annuloplasty ring dehiscence is a well described mode of mitral valve repair failure. Defining the mechanisms underlying dehiscence may facilitate its prevention. METHODS Factors that govern suture dehiscence were examined with an ovine model. After undersized ring annuloplasty in live animals (n = 5), cyclic force (FC) that acts on sutures during cardiac contraction was measured w...
متن کاملMitral Valve Annuloplasty Ring Dehiscence Diagnosed Intraoperative With Real-Time 3D Transesophageal Echocardiogram
Mitral annular calcification (MAC) is often a result of the accumulation of lipids around the annulus, which can lead to degeneration and calcification of the valve. Multiple risk factors have been associated with the progression of MAC and life-threatening complications such as the early mitral valve annuloplasty dehiscence. Our case describes the different risk factors for annuloplasty dehisc...
متن کاملSystematic evaluation of the flexible and rigid annuloplasty ring after mitral valve repair for mitral regurgitation.
OBJECTIVES Mitral annulus reconstruction is now a common surgical procedure for the treatment of mitral regurgitation. However, there are still controversies in the selection of materials for annuloplasty in the clinical controlled studies available. The purpose of the present systematic review of the literature is to address whether a flexible ring is superior to a rigid ring in terms of impro...
متن کاملDehiscence of mitral valve annuloplasty: a three-dimensional diagnosis.
A 74-year old patient underwent aortic valve replacement and mitral annuloplasty (Edwards Lifesciences Physioring, 34 mm). Five weeks post-surgery, he was readmitted because of heart failure due to a severe residual mitral regurgitation. Three-dimensional (3D) echocardiography clearly demonstrated the posterolateral area of dehiscence. He underwent successful surgical refixation (Fig. 1 and Sup...
