It has been demonstrated that rheumatic mitral valve stenosis (RMVS) is associated with an increase in markers of endothelial dysfunction. It is not known whether this association indicates an impairment of flow-mediated dilatation (FMD) of the vascular endothelium. Thirty patients with RMVS and 30 healthy subjects were studied. FMD in patients with RMVS was significantly smaller than in healthy controls (11.9+/-0.4% vs 15.4+/-0.70%, p=0.003). The absolute change in brachial artery diameter in patients with RMVS was also significantly smaller than in healthy subjects (0.42+/-0.26 mm vs 0.64+/-0.32 mm, p<0.001). These findings suggest that vascular endothelial function is altered in patients with RMVS.

In recent years, the use of transcatheter valve-in-valve implantation in the mitral position (TMVI) for the treatment of mitral valve pathology following ring or bioprosthetic implantation has emerged as a less invasive option in comparison to repeated mitral valve surgery (RMVS). We aimed to compare the early and mid-term results of these two strategies. We retrospectively analyzed all patients who underwent a mitral intervention in our institution between 2005 and 2022.

Circulating microvesicles (MVs) have been studied in heterogeneous, divergent, and rather small patient populations with cardiovascular risk . Therefore, we measured endothelial (EMVs), platelet (PMVs) and erythrocyte (RMVs) MVs in patients with divergent cardiovascular risk. We then compared them to coronary artery disease (CAD) and healthy subjects and identified independent MVs' predictors.

Objectives: There is still ongoing debate about the benefits of robotic assistance (R-MVS) in comparison with video assistance (V-MVS) in minimally invasive mitral valve surgery. This study aims to update the current evidence.
Methods: Three propensity score-matched studies published from 2011 to 2021 were included with a total of 1193 patients operated on from 2005 (R-MVS: 536, V-MVS: 657).

Background: Robotic-assisted mitral valve surgery (RMVS) is becoming an increasingly performed procedure in cardiac surgery, however, its true safety and efficacy compared to the gold standard conventional sternotomy approach [conventional sternotomy mitral valve surgery (CSMVS)] remains debated. The aim of this meta-analysis was to provide a comprehensive analysis of all available literature comparing RMVS to CSMVS.
Methods: An electronic search of five databases was performed to identify all relevant studies comparing RMVS to CSMVS.

Objective: This study has been compared the effectiveness of different surgical methods in the treatment of mitral regurgitation (MR) in adults by using the network meta-analysis method, so as to provide reference for clinical selection of the best surgical scheme.
Methods: The PubMed, EMBASE, the Cochrane Library, CNKI, and Chongqing VIP Information databases were comprehensively searched until December 2020. We collected retrospective comparative studies on surgical procedures including 3D endoscopic mitral valve surgery (3D-MVS), robot-assisted mitral valve surgery (R-MVS); totally thoracoscopic mitral valve surgery (T-MVS), small incision mitral valve surgery (M-MVS), and traditional thoracotomy mitral valve surgery (C-MVS).
