Cleft of the mitral valve is a rare cause of the congenital mitral regurgitation. Isolated cleft is uncommon finding and is more often found associated with some form of endocardial cushion defect. Cleft of the septal leaflet is found much more often than the defect in the posterior leaflet. Mitral clefts can extend to the mitral annulus or they can be less ''deep'' and show only minor regurgitation. Clinical importance of the isolated cleft of the mitral valve (ICMV) is that it can be successfully corrected by surgery and that it can have good long-term results.

Posterior Mitral Leaflet

The article presents a single-center experience of surgical treatment of patients with severe mitral regurgitation(MR) caused by mitral valve prolapse (MVP). The study is based on long-term results of reconstructive interventions on the mitral valve (MV) of the UCCC of the Ministry of Health of Ukraine. The purpose of this work is to determine the factors that influence the long-term results of surgical treatment of MR in prolapse of the mitral valve leaflets. Material and methods.From January 1, 2011, to January 1, 2018, 146 patients with severe MR were operated on the basis of the UCCC, which was conditioned by the prolapse of mitral valve leaflets. Results.Long-term results were analyzed in 95.2% of patients. The average postoperative follow-up period was 39.7 ± 19.8 months. The overall mortality rate was 1.4%. Freedom from moderate and severe MR in the remote postoperative period decreased to 94.2%, compared to the early postoperative period. Residual MR was absent in 17 (12.4%) patients. In 76 (55.5%) patients trivial MR was detected, in 36 (26.3%) there was a mild MR, in 3 (2.2%) a moderate MR. In 5 (3.6%) patients, a severe MR was detected during the observation. Using statistical methods, it was found that the anatomical variant of MVP influences the prognosis of treatment results in the long postoperative period with worse results in the group with isolated prolapse of the anterior leaflet. Also, the dependence of the results on the applied surgical techniques with better results in annuloplication using the annuloplasty rings and in the application of resection of the posterior mitral leaflet. On the basis of statistics, a prognostic model for the evaluation of MV repair results in the distant period was developed. The height of coaptation of mitral leaflets was determined as one of the indicators for predicting the results of surgical treatment of MR with MVP. Conclusions: 1. In most cases, a successful mitral valve repair is possible with the MVP. 2. A good immediate result does not mean keeping it in the long term. 3. The long-term results of MV reconstruction depend on the anatomical variant of the MVP, with worse results in patients with isolated prolapse of the anterior mitral leaflet. 4. The result of MV repair depends on the surgical techniques used, with better results when using the annuloplasty rings and resection of the posterior mitral leaflet. 5. The height of the coaptation of the MV leaflets is an indicator that allows predicting the outcome of surgical treatment in the long postoperative period.

The sliding leaflet plasty of the posterior mitral leaflet is a complex procedure, both lengthy and technically challenging. A simple alternative is desirable, particularly for a minimally invasive approach. We report a distinct substitute to the conventional sliding leaflet plasty that included triangular resections of P2 and P3 using a robot. These multiple triangular resections enabled a successful mitral valve repair with satisfactory clinical and echocardiographic results. Recognizing the complexity of sliding leaflet plasties, we note that multisegment triangular resections seem to be an easy, expeditious, and effective alternative for the posterior leaflet that is readily performed via a robotic endoscopic approach.

Cardiac papillary fibroelastoma (CPF) is the most common valvular tumour of the heart and the second most common primary cardiac tumour. Fewer than 50 cases being reported in the literature [1]. As the advancement in 3D echocardiography, its diagnosis in living patient is become easy. The CPF could be found on valve leaflets, chordae tendineae, and both ventricles. We present an interesting case of the CPF originating from the posterior leaflet of the mitral valve confusing with vegetation or annular calcification. The patient underwent successful surgical removal of the PFE

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.

Background Three-dimensional dynamics of the 3 individual scallops within the posterior mitral leaflet during acute ischemic mitral regurgitations have not been previously measured. Methods Radiopaque markers were sutured to the mitral annulus, papillary muscle tips, and leaflet edges in 13 sheep. Immediately postoperatively, under open-chest conditions, 3-D marker coordinates were obtained using high-speed biplane videofluoroscopy before and during echocardiographically verified acute ischemic mitral regurgitation produced by occlusion of the left circumflex coronary artery. Results During acute ischemic mitral regurgitation, at end systole, the anterolateral edge of the central scallop was displaced 0.8±0.9 mm laterally and 0.9±0.6 mm apically away from the anterolateral scallop; such displacement correlated with lateral displacement of the lateral annulus (R 2 =0.7, SEE=0.7 mm, P <0.001) and movement of the right lateral annulus away from the nonischemic anterior papillary tip (R 2 =0.6, SEE=0.8 mm, P =0.002), respectively. End-systolic displacement of the posteromedial edge of the central scallop was 1.4±0.9 mm anteriorly and 0.9±0.6 mm laterally away from the posteromedial scallop, corresponding to anterior displacement of the mid-lateral annulus (R 2 =0.5, SEE=1.0 mm, P <0.001). Conclusions Malcoaptation of the scallops within the posterior leaflet during acute left ventricular ischemia is a novel observation. The primary geometric mechanism underlying scallop malcoaptation in acute ischemic mitral regurgitation was annular dilatation, which hindered leaflet coaptation by drawing the individual scallops apart. These findings support the use of annular reduction in the repair of ischemic mitral regurgitation and also suture closure of prominent subcommissures between posterior leaflet scallops.
