“…In Panicker's study, with on-table echocardiography showing no residual MR in both groups, it is interesting to see that the recurrence of ++/+++ MR at 5 years was 10/42 (23.1%) vs 11/70 (15.7%) in the rigid group vs flexible group, respectively. These interesting results for the flexible rings are in keeping with previously reported data [11] and once again support the reliability of the flexible rings in the context of degenerative MV disease. Kanemitsu et al have shown a freedom from recurrence of significant MR after flexible ring of 92.5 ± 2.2% at 10 years and 73.1 ± 7.1% at 15 years.…”

The choice of ring for mitral valve repair is still largely left to the surgeon's preferences and there are no specific guidelines regulating this decision. Despite this previous researches have described important features appertaining to each of the different types of rings currently available. Particularly, the debate is still open in regards to the flexibility that these devices should or should not have. Later in this issue of the Journal, Panicker and colleagues have reported their results with flexible and rigid rings in mitral valve repair. The results are very interesting and once again are highlighting the importance of using the right ring for the right disease.

“…Because this patient was 19-years-old, MVR with a mechanical valve was acceptable from the viewpoint of valve durability, but with mental retardation, it was more convenient to plan avoidance of postoperative anticoagulant therapy. The surgeon in this case has performed more than 1500 cases of MVP, with a survival rate and 10-year freedom from reoperation of 89.3% AE 2.2% and 96.4% AE 1.4%, respectively; and 83.5% AE 3.2% and 95.3% AE 1.7%, respectively, 15 years after MVP in the usual cases of degenerative MR. 4 The long-term survival and reoperation-free rates were satisfactory, but in this case, the cause of MR was different from that of the usual adult patient. Long-term follow-up is necessary.…”

A 19-year-old man with Down syndrome had congenital mitral regurgitation. He had slight mental retardation and difficulty in performing independent oral drug administration. We planned mitral valve plasty to avoid postoperative anticoagulant therapy. The mitral valve lesions were complicated. A prolapsed anterior mitral leaflet, shortened posterior leaflet, abnormal cleft, abnormal papillary muscle, and enlarged annulus were observed. Successful mitral valve plasty was performed using several techniques. The postoperative course was uneventful, and no significant mitral regurgitation was found.

“…There were 8 patients who required reoperation, the cause of reoperation in 2 patients was dilated mitral annulus due to abnormal shape of the Duran ring, that caused in improper annular fixation. In study performed by Kanemitsu et al (6) , mortality rate and freedom from reoperation were not significant. The causes of reoperation in three patients were recurrent leaflet prolapse in two and leaflet sclerosis in one.…”

Background the most common clinically presented valvular heart disease is mitral regurgitation (MR). Mitral valve repair is considered the surgery of choice for mitral regurgitation. Objective: The aim of the current work was to evaluate the early result of mitral repair with flexible and rigid annuloplasty devices in degenerative mitral regurgitation. Patients and Methods: This prospective study included a total of 64 patients with degenerative mitral regurgitation undergoing surgery for mitral valve repair with either a flexible or rigid annuloplasty device, attending at Department Cardiothoracic Surgery, Zagazig University Hospitals. This study was conducted between September 2017 and June 2020. We evaluated all patients after 6 months of surgery. Results: According to early mortality there were 2 patients in flexible group, and 1 patient in rigid one with no significant differences. There were also no significant differences according to failure of repair. Conclusion:It could be concluded that in spite of type of annuloplasty devices used, the early outcomes of mitral valve repair with rigid or flexible device show good results in our prospective study, but there were statistical differences between both groups regarding postoperative left ventricular dimension and function.
