Is Physiologic Annular Dynamics Preserved After Mitral Valve Repair With Rigid or Semirigid Ring?

Three-Year Results of Repaired Barlow Mitral Valves via Right Minithoracotomy versus Median Sternotomy in a Randomized Trial

“…Finally, we always completed the repair procedure with the use of an annuloplasty ring to ensure a durable result. In most of the cases we used a semirigid remodeling ring able to follow the physiologic movements of the mitral valve (Sorin Memo3D) with the aim of supporting the annulus without compromising its dynamics which can be particularly attractive in these patients [19,20]. The present study reports a 2.5% operative mortality in each group, which could be a higher figure than expected in this population.…”

Initial Experience With a New Mitral Ring Designed to Simplify Length Determination of Neochords

“…Early results with the Memo 3D have been previously reported [24]. In addition, Nishi and colleagues [13] and Ryomoto and colleagues [25] demonstrated that after Memo 3D implantation, movement of the anterior and posterior annulus, as well as changes in the mitral annulus throughout the cardiac cycle, is preserved. Wan and colleagues [26] published data of 34 patients treated with the Memo 3D ReChord and compared these data with 32 patients with the Memo 3D.…”

Year in review

“…A recent study by Ryomoto et al [38] demonstrated the ability of rigid rings to restore the physiologic saddle shape of the annulus, at the expense of reduced annular motion. Flexible rings, on the other hand, preserved annular dynamics; however, they could not consistently restore the annulus to its normal physiologic shape.…”
