Recently, mitral valve repair has been the mainstream of the operation for the treatment of mitral valve regurgitation. In particular, chorda reconstruction with artificial chordae is useful for the anterior leaflet. However, there has been no established method determining the length of chordae. In this report, we performed mitral valve repair using Memo 3D ReChord ring which enables to decide the length of chordae more easily. It is based on the concept of folding leaflet technique by Garcia et al. We used this ring in 7 patients (of which 2 were reoperation) in our institution. There was no postoperative death nor complication. Postoperative transthoracic echocardiography showed class 0~Ⅰ mitral valve regurgitation in each case at discharge. This ring helps to make the repair more reproducible and we consider that it enables to decide the length of chordae more easily even in reoperative cases.
