Semirigid partial annuloplasty band allows dynamic mitral annular motion and minimizes valvular gradients: an echocardiographic study

Mitral valve gradient after valve repair of degenerative regurgitation with restrictive annuloplasty

“…2 It is intuitive that some narrowing of the valve orifice will occur after the use of these techniques, and indeed the literature supports such a concept. 3 The effects of such repair have not been well studied, however, and only a few reports have been published to date. 4,5 We studied our experience in this setting to better understand the effect of mitral valve repair as it relates to long-term valve gradient.…”

Initial experience of mitral valve repair using the Carpentier-Edwards Physio II annuloplasty ring

“…Despite this, mitral annuloplasty has become one of the key features of MV repair with proven short-and long-term efficacy [6,7]. The theory underpinning what constitutes a 'gold standard' annuloplasty ring is hotly debated [14]. An entirely rigid ring offers robust annular remodelling potential yet runs the risk of inducing SAM and left-ventricular outflow tract obstruction [15].…”

Improvement of Mitral Valve Coaptation with Supraannular Plication of the Posterior Annulus —A Newly Designed Strip for Posterior Annular Plication—

“…For the fully opened valve, the ratio of septal-lateral and transverse dimensions was relatively low, 10) which results in a relatively large intercommissural dimension and a small septal-lateral dimension with SA. Nevertheless, the valve orifice area, the indexed valve area, and the transvalvular pressure gradient were within clinically normal ranges in all patients.…”
