Key result
Novel adjustable mitral annuloplasty ring increases maximum coaptation height 7 mm in ex vivo swine.
Why the study?
Residual and recurrent mitral regurgitations may be corrected by improving mitral leaflets coaptation with a novel adjustable mitral annuloplasty ring on the beating heart.
Does a novel adjustable mitral annuloplasty ring improve mitral leaflets coaptation height in an ex vivo swine heart model?
Does a novel adjustable mitral annuloplasty ring improve mitral leaflets coaptation height in an ex vivo swine heart model?

Tozzi et al. (2016) studied Mitral regurgitation (n=8). Adjustable mitral annuloplasty ring was evaluated on Leaflets coaptation height at P2 level. A novel adjustable mitral annuloplasty ring allowed a maximum coaptation height increase of 7 mm and a mean pressure gradient of 1.7 ± 0.3 mm Hg in an ex vivo swine heart model.
