Closed Mitral Commissurotomy

Purpose: To evaluate long-term survival and valve-related complications as well as prognostic factors for mid- and long-term outcome after closed mitral commissurotomy, covering a follow-up period of 14 years. Material and Methods: Between 1989 and 2003, 36 patients (28 women and 8 men, mean age 28.8 6.1 years) underwent closed mitral commissurotomy at our institution. The majority of patients were in New York Heart Association (NYHA) functional class IIB, III, or IV. Indication for closed mitral commissurotomy was mitral stenosis. Closed mitral commissurotomy was undertaken with a Tubbs dilator in all cases. Median operating time was 2.5 hours 30 minutes. Results: After closed mitral commissurotomy, the mitral valve areas of these patients were increased substantially, from 0.9 to 2.11 cm2. No further operation after initial closed mitral commissurotomy was required in 86% of the patients (n = 31), and NYHA functional classification was improved in 94% (n = 34). Postoperative complications and operative mortality were not seen. Follow-up revealed restenosis in 8.5% (n = 3) of the patients, minimal mitral regurgitation in 22.2% (n = 8), and grade 3 mitral regurgitation in 5.5% (n = 2) patients. No early mortality occurred in closed mitral commissurotomy patients. Reoperation was essential for 5 patients following closed mitral commissurotomy; 2 procedures were open mitral commissurotomies and 3 were mitral valve replacements. No mortality occurred in these patients. Conclusions: The mitral valve area was significantly increased and the mean mitral valve gradient was reduced in patients after closed mitral commissurotomy. Closed mitral commissurotomy is a safe alternative to open mitral commissurotomy and balloon mitral commissurotomy in selected patients.

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.

Abstract Background Rheumatic heart disease (RHD) is still a concerning issue in developing countries. Among delayed RHD presentations, rheumatic mitral valve stenosis (MS) remains a prevalent finding. Percutaneous transvenous mitral commissurotomy (PTMC) is the intervention of choice for severe mitral stenosis (MS). We aimed to assess the mid-term outcome of PTMC in patients with immediate success. Methods In this retrospective cohort study, out of 220 patients who had undergone successful PTMC between 2006 and 2018, the clinical course of 186 patients could be successfully followed. Cardiac-related death, undergoing a second PTMC or mitral valve replacement (MVR) were considered adverse cardiac events for the purpose of this study. In order to find significant factors related to adverse cardiac outcomes, peri-procedural data for the studied patients were collected.The patients were also contacted to find out their current clinical status and whether they had continued secondary antibiotic prophylaxis regimen or not. Those who had not suffered from the adverse cardiac events were additionally asked to undergo echocardiographic imaging, in order to assess the prevalence of mitral valve restenosis, defined as mitral valve area (MVA) < 1.5 cm2 and loss of ≥ 50% of initial area gain. Results During the mean follow-up time of 5.69 ± 3.24 years, 31 patients (16.6% of patients) had suffered from adverse cardiac events. Atrial fibrillation rhythm (p = 0.003, HR = 3.659), Wilkins echocardiographic score > 8 (p = 0.028, HR = 2.320) and higher pre-procedural systolic pulmonary arterial pressure (p = 0.021, HR = 1.031) were three independent predictors of adverse events and immediate post-PTMC mitral valve area (IMVA) ≥ 2 cm2 (p < 0.001, HR = 0.06) was the significant predictor of event-free outcome. Additionally, follow-up echocardiographic imaging detected mitral restenosis in 44 patients (23.6% of all patients). The only statistically significant protective factor against restenosis was again IMVA ≥ 2 cm2 (p = 0.001, OR = 0.240). Conclusion The mid-term results of PTMC are multifactorial and may be influenced by heterogeneous peri-procedural determinants. IMVA had a great impact on the long-term success of this procedure. Continuing secondary antibiotic prophylaxis was not a protective factor against adverse cardiac events in this study. (clinicaltrial.gov registration: NCT04112108).

Background To quantify valvular morphological assessment, some two-dimensional (2D) and three-dimensional (3D) scoring systems have been developed to target the patients for balloon mitral valvuloplasty; however, each scoring system has some potential limitations. To achieve the best scoring system with the most features and the least restrictions, it is necessary to check the degree of overlap of these systems. Also the factors related to the accuracy of these systems should be studied. We aimed to determine the correlation between the 2D Wilkins and real-time transesophageal three-dimensional (RT3D-TEE) scoring systems. Methods This cross-sectional study was performed on 156 patients with moderate to severe mitral stenosis who were candidates for percutaneous balloon valvuloplasty. To morphologic assessment of mitral valve, patients were examined by 2D-transthoracic echocardiography and RT3D-TEE techniques on the same day. Results A strong association was found between total Wilkins and total RT3D-TEE scores (r = 0.809, p < 0.001). The mean mitral valve area assessed by the 2D and 3D was 1.07 ± 0.25 and 1.03 ± 0.26, respectively, indicating a mean difference of 0.037 cm2 (p = 0.001). We found a strong correlation between the values of mitral valve area assessed by 2D and 3D techniques (r = 0.846, p < 0.001). Conclusion There is a high correlation between the two scoring systems in terms of evaluating dominant morphological features. Partially, mitral valve area overestimation in the 2D-transthoracic echocardiography and its inability to assess commissural involvement as well as its dependence on patient age were exceptions in this study.
