Several techniques are currently in use for mitral valve reconstruction. We report a mitral repair case in which the use of a combination of different surgical techniques resulted in the necessary correction. A 47-year-old woman underwent surgical intervention to treat severe mitral valve insufficiency due to A1/A2/A3 and P2 prolapsed valve tissue. A combination of quadrangular resection, sliding leaflet, single chordal transposition, "flip-over" leaflet, and ring annuloplasty techniques were applied, and postsurgical correct valve function was documented by results of a left ventricular saline filling test and transesophageal echocardiography control. Complex mitral valve repairing techniques can be combined to reestablish valvular function.

Background and aim of the study: Mitral repair is now as the treatement of choice in patients suffering mitral regurgitation due to mitral valve prolapse or flail. However, mitral valve repair demands the mitral valve morphology being feasible for repair. The study aims at evaluating transthoracic and transesophageal echocardiographic features in consecutive patients with mitral valve prolapse or flail undergoing surgical repair at Hue Central Hospital. The correlation between preoperative and intraoperative echocardiographic features and surgical findings in these patients. These echocardiographic data may predict the surgical outcome. Methods: From December 2010 to January 2013, 73 patients (37 men, 36 women; average age 37.5) were recruited into the study. All patients had degenerative mitral valve disease causing important regurgitation and underwent systematic preoperative transthoracic echocardiography, preoperative and intraoperative transesophageal echocardiography for delineation of six segments (scallops) of anterior and posterior leaflets. Results: Among 73 patients, 64 patients were in fibroelastic deficiency (87.7%) and 9 patients suffered Barlow disease (12.3%). Mitral valve repair was performed in 52 patients (71.2%) and mitral replacement was performed in 21 patients (28.8%). All 52 mitral valve repair (81.3%) and 12 mitral valve replacement (18.7%) was performed in fibroelastic deficiency patients. All 9 Barlow patients must undergo mitral valve replacement (100%). A prolapse or flail of mitral valve in 73 patients was documented by transthoracic and transesophageal echocardiography and confirmed on surgical inspection. Accuracy of transthoracic echocardiography was (89.0%) and accuracy of transesophageal echocardiography was (91.8%) in identifying mitral valve segments prolapse or flail. Success rate of mitral valve repair was (98.0%) in prolapse of 1 or 2 segments, but was low (36.0%) in prolapse > 3 segments. Success rate of mitral valve repair was (96.6%) in prolapse of posterior leaflet, but was (63.6%) in prolapse anterior leaflet or bileaflet. Conclusion: - Mitral valve repair was favorable in fibroelastic deficiency patients, but difficult in Barlow patients. - Accuracy of transthoracic and transesophageal echocardiography was high in identifying mitral valve segments prolapse or flail. - Success rate of mitral valve repair was high in prolapse of 1 or 2 segments. - Success rate of mitral valve repair was high in in prolapse of posterior leaflet.

Mitral Repair

Bulging subaortic septum in hypertrophic cardiomyopathy is a potential risk factor for systolic anterior motion after mitral valve repair. Systolic anterior motion may cause postoperative mitral regurgitation and left ventricular outflow tract obstruction despite conservative management. During “minimally invasive endoscopic” and “robotic” mitral repair procedures, systolic anterior motion is prevented with concomitant septal myectomy through the mitral valve orifice. Technically, the exposure of the bulging subaortic septum is traditionally done with detachment of the anterior mitral leaflet from its annulus, leaving a 2-mm rim of leaflet attached to the annulus. The leaflet is then sutured after myectomy. As an alternative technique in robotic surgery, the exposure of the subaortic septum is feasible without anterior leaflet incision with the use of dynamic atrial retractor in mitral repair procedures. Here, we present a patient who underwent concomitant robotic mitral valve repair with posterior chordal implantation, ring annuloplasty, and septal myectomy without anterior leaflet incision using the da Vinci surgical system.

ObjectivesDifferences in terms of safety and efficacy of percutaneous edge-to-edge mitral repair between patients with functional and degenerative mitral regurgitation (MR) are not well established. We performed a systematic review and meta-analysis to clarify these differences.MethodsPubMed, EMBASE, Google scholar database and international meeting abstracts were searched for all studies about MitraClip. Studies with <25 patients or where 1-year results were not delineated between MR aetiology were excluded. This study is registered with PROSPERO.ResultsA total of nine studies investigating the mid-term outcome of percutaneous edge-to-edge repair in patients with functional versus degenerative MR were included in the meta-analysis (n=2615). At 1 year, there were not significant differences among groups in terms of patients with MR grade≤2 (719/1304 vs 295/504; 58% vs 54%; risk ratio (RR) 1.12; 95% CI: 0.86 to 1.47; p=0.40), while there was a significantly lower rate of mitral valve re-intervention in patients with functional MR compared with those with degenerative MR (77/1770 vs 80/818; 4% vs 10%; RR 0.60; 95% CI: 0.38 to 0.97; p=0.04). One-year mortality rate was 16% (408/2498) and similar among groups (RR 1.26; 95% CI: 0.90 to 1.77; p=0.18). Functional MR group showed significantly higher percentage of patients in New York Heart Association class III/IV (234/1480 vs 49/583; 16% vs 8%; p<0.01) and re-hospitalisation for heart failure (137/605 vs 31/220; 23% vs 14%; p=0.03). No differences were found in terms of single leaflet device attachment (25/969 vs 20/464; 3% vs 4%; p=0.81) and device embolisation (no events reported in both groups) at 1 year.ConclusionsThis meta-analysis suggests that percutaneous edge-to-edge repair is likely to be an efficacious and safe option in patients with both functional and degenerative MR. Large, randomised studies are ongoing and awaited to fully assess the clinical impact of the procedure in these two different MR aetiologies.

Background: Tricuspid edge to edge repair (TEER) is a novel treatment for severe tricuspid regurgitation and is highly dependent on intraprocedural image quality. To date, transesophageal echocardiography (TEE) has been the primary imaging modality used to guide TEER. The role of intracardiac echocardiography (ICE) has not been assessed. The objective of this study was to describe the use and role of 2-dimensional ICE in the early experience of TEER. Methods: Consecutive patients undergoing TEER (with or without concomitant mitral repair) with off-label use of MitraClip (Abbott, Santa Clara, CA) were included in the study. Utilization of 2-dimensional ICE in comparison with TEE imaging were collected in each procedure through retrospective review of the procedural reports and images. Results: Of 42 TEER cases, ICE was used in 15 (36%) and concomitant mitral repair was performed in 37 (86%). ICE was increasingly used over time for TEER. ICE was able to visualize the tricuspid leaflets with high resolution and provided superior leaflet visualization to TEE in 40% of cases where it was used. Patients treated with ICE guidance tended to have a greater baseline severity of tricuspid regurgitation compared with patients treated with TEE guidance alone (8/15 [53%] massive or greater tricuspid regurgitation versus 6/27 [22%]; P =0.09). Degree of tricuspid regurgitation reduction was similar with TEE alone versus ICE plus TEE guidance (1.9±1.0 versus 2.1±1.1 grade reduction, P =0.28). Conclusions: ICE was increasingly used in the early experience of TEER over time. ICE facilitates leaflet visualization for grasping and is a useful adjunct to TEE during TEER.
