“…When we looked at 30 patients with severe mitral stenosis to see what the immediate impact of successful percutaneous balloon mitral valvuloplasty on right and left ventricular functions was, we found that 70% of patients had a significant reduction in LA diameter after PBMV, which is consistent with what sowdagar and his co-workers found when they studied the same patients [7].…”

“…This reflects greater left ventricular fullness and contractility and is mostly explained by mechanical relive of the right ventricle.Sowdagar and his colleagues evaluated 30 patients with severe MS to assess the immediate effect of a successful percutaneous balloon mitral valvuloplasty on right and left ventricular functioning. They came to the same conclusion [7].…”

LA/LAA dysfunction is a serious concern in patients with severe mitral stenosis, which may lead to blood stasis and thromboembolic consequences, as well as heart failure.In this research, we aimed to examine the impact of PBMV on LA/LAA function, specifically focusing on mitral annulus Sa velocity, SEC grade and LAA TDI parameters, in order to identify the determinants of improved LA/LAA function. Methods: Preliminary research was undertaken between June 2020 and April 2022 at a Tertiary Care Hospital in the United States. At the National Heart Institute's Cardiology Department, a total of 50 patients with symptomatic, isolated, severe mitral stenosis underwent PBMV surgery. Dyspnea was a common symptom in more than half of our patients, most of whom were in their 30s and 40s (NYHA class II). An improved LA/LAA SEC grade, decreased mitral valve diastolic pressure gradient and decreased diastolic left atrial diameter were all seen following PBMV. After PBMV, mitral annular Sa velocity, LAAEV, and LAAFV were all significantly improved. " We also found that improvement in LA/LAA function after PBMV was significantly predicted by mitral annular Sa velocity. The SEC grade of the LA/LAA was shown to be a major predictor of improvement in LA/LAA function following PBMV. Our findings showed that the mital annular Sa velocity cutoff value was 5.5 cm/s was the ideal speed for predicting an inactive LAA. The cutoff value for LAAEV in our investigation was 25 cm/sec for the prediction of inactive LA/LAA. Conclusion: Pre-PBMV inactivity was predicted by lower Sa-wave velocity; after PBMV inactivity was predicted by higher Sa-wave velocity, higher LAAEV, lower SEC grade, lower left atrial diameter, larger MVA and lower PASP. Specifically, lower left atrial diameter, larger MVA and lower PASP were associated with improved LA function after PBMV.

Aims Percutaneous mitral balloon valvotomy PMBV is an acceptable alternative to Mitral valve surgery for patients with mitral stenosis. The purpose of this study was to explore the immediate results of PMBV with respect to echocardiographic changes, outcomes, and complications, using a meta -analysis approach. Methods MEDLINE, and EMBASE databases were searched (01/2012 to 10/2018) for original research articles regarding the efficacy and safety of PMBV. Two reviewers independently screened references for inclusion and abstracted data including article details and echocardiographic parameters before and 24–72 h after PMBV, follow-up duration, and acute complications. Disagreements were resolved by third adjudicator. Quality of all included studies was evaluated using the Newcastle-Ottawa Scale NOS. Results 44/990 references met the inclusion criteria representing 6537 patients. Our findings suggest that PMBV leads to a significant increase in MVA (MD = 0.81 cm 2 ; 0.76–0.87, p < 0.00001), LVEDP (MD = 1.89 mmHg; 0.52–3.26, p = 0.007), LVEDV EDV (MD = 5.81 ml; 2.65–8.97, p = 0.0003) and decrease in MPG (MD = −7.96 mmHg; −8.73 to −7.20, p < 0.00001), LAP (MD = −10.09 mmHg; −11.06 to −9.12, p < 0.00001), and SPAP (MD = −15.55 mmHg; −17.92 to −13.18, p < 0.00001). On short term basis, the pooled overall incidence estimates of repeat PMBV, mitral valve surgery, post-PMBV severe MR, and post-PMBV stroke, and systemic thromboembolism were 0.5%, 2%, 1.4%, 0.4%, and 0.7%% respectively. On long term basis, the pooled overall incidence estimates of repeat PMBV, mitral valve surgery, post-PMBV severe MR, and post-PMBV stroke, systemic thromboembolism were 5%, 11.5%, 5.5%, 2.7%, and 1.7% respectively Conclusion PMBV represents a successful approach for patients with mitral stenosis as evidenced by improvement in echocardiographic parameters and low rate of complications.

“…The results of the current study showed that multitrack balloon technique can significantly improve MS as proved by significant reduction of the means of gradient pressure, RVSP, and LA pressure. Actually, PMV is an effective procedure for MS with any of its technique either by Inoue balloon, metallic commissurotome, or multitrack double balloon as reported by Sharieff et al [9], Sherif et al [10], Sowdagar and Subba [11], Alkhouly et al [12].…”

Background: Percutaneous mitral balloon valvuloplasty is the main procedure in mitral stenosis (MS). It can replace surgical commissurotomy in many cases; however, mitral regurgitation (MR) remains the major procedure complication. Objectives: This study was conducted to investigate predictors of MR as a complication following percutaneous mitral valvuloplasty (PMV) using multitrack balloon technique. Methods: This cohort study was conducted at both Menoufia University Hospital and Mabaret Misr Elkadima Hospital. We enrolled 121 patients with moderate to severe MS who were subjected to PMV using multitrack balloon technique during the period from October 2017 to October 2019. Transthoracic echocardiographic evaluation was performed for all patients before and after the procedure. Patients who developed severe MR post procedure were compared with other patients to identify important distinction points. Results: Most patients (N = 109, 90.1%) developed no/mild MR (group A), whereas 12 (9.9%) patients developed severe MR (group B) after PMV. Those who developed severe MR had significantly higher weight, height, body mass index, and body surface area (P value < 0.001 for each). Also, there was a significant difference between both groups regarding pre-operative Wilkins score (8.7 ± 1.3 for severe MR versus 7.9 ± 1.2 for No/Mild MR, P = 0.046). Patients who developed severe MR had higher incidence of other valvular lesions such as mild aortic regurgitation (91.7% versus 36.7%, P < 0.001), higher mitral valve (MV) commissural calcification (50.0% versus 14.7%, P = 0.008), pre-operative MR (100.0% versus 35.8%, P < 0.001), higher prevalence of atrial fibrillation (100.0% versus 38.5%, P < 0.001). Regarding balloon sizing, it was significantly higher among patients who developed severe MR compared with those having mild or no MR (P = 0.001). Multivariate regression analysis identified MV balloon sizing How to cite this paper:
