Annular dynamics after mitral valve repair with different prosthetic rings: A real-time three-dimensional transesophageal echocardiography study

Abstract

Although mitral regurgitation was well controlled by all of the types of rings that were utilized in the present study, we demonstrated that the annulus motion and annulus shape differed according to the type of prosthetic ring that was used, which might provide important information for the selection of an appropriate prosthetic ring.

Acute Effect of Mitral Valve Repair on Mitral Valve Geometry

“…Annular sphericity increases with annular dilatation to a more circular-shaped annulus compared with that in a nondilated ellipsoid annulus. 23,24 We found the mean annular sphericity index to be decreased to 0.77 after MVR, which correlates with the 3:4 ratio of our most frequently implanted CE Physio annuloplasty ring (annular sphericity index of 0.75). Moreover, the end-systolic AHCWR also decreased from 0.19 to 0.12, showing no significant changes throughout the cardiac cycle after MVR.…”

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.…”

“…This semirigid ring contains an elastic nitinol and titanium alloy core that proved to accommodate the anatomic saddle shape of the mitral valve annulus and to restore the physiologic diameter ratio [13]. The core is enclosed in a sewing ring made of silicone and polyester fabric.…”
