چکیده
Abstract Objective interventional edge-to-edge repair by MitraClip ™ is widely demonstrated to be able reduce the degree of MR in patients with high surgical risk. The left atrial (LA) dysfunction severe associated poor prognosis and its changes after MV reported several studies. While, little known about full evaluation LA function Two-dimensional speckle echocardiography tracking (2D STE) Materials methods from March 2015 December 2021, clinical echocardiographic data 67 who underwent Mitraclip™ implantation our division were evaluated for function. Strain Reservoir (S_R), Conduit (S_Cd), Contractile (S_Ct), emptying Fraction (LAEF_4CH), LAESV (Left end-systolic volume), LAEDV end-diastolic volume) at baseline, 1 month, 6 months year follow up assessed. variation continuous variables was using a student T test paired data. categorical between ANOVA test. Multiple Bonferroni comparison conducted as post hoc analysis P values <0.05 considered significant. Results etiology primary 29,2% secondary 70,8% included patients. 3+ 16,9% 4+ 81,5%. When compared baseline statistically significant improvement observed LAEF_4CH (p 0.006 <0.001) S_R 0.013) S_Cd 0.033). month S-R (shown Table 1). Finally, no S_Ct different time point analyzed. Conclusions MitraClip™ procedure allows hemodynamic remodeling which can detected 2D STE through an These emphasize hypothesis that these parameters represent advanced method evaluate response device implantation.

متن کاملCombined MitraClip implantation and left atrial appendage occlusion - "because it's there" revisited?
In an interview with the New York Times in 1923, George Mallory, who was to die on his third attempt to climb Mount Everest (his body was not found until in 1999), was asked why he wanted to climb the mountain. His reply was ‘‘Because it’s there’’. This phrase has since become iconic, used to justify any action or ambition that otherwise has no justification. In their article published in this ...

periprocedural intracardiac echocardiography with transesophageal echocardiography performed 6 months after transseptal puncture. We agree with Ren et al. that it is not clear whether iASD persistence accounts for adverse outcomes after MitraClip procedures or whether the persistence of an ASD just reflects adverse conditions, which lead to higher mortality and impaired functional outcomes. The...
متن کاملEchocardiographic [correction of Ehocardiographic] evaluation of regional left atrial function after rapid atrial pacing.
Rapid regular atrial pacing (RAP) produces changes in atrial function similar to those caused by atrial fibrillation in animal models. Left atrial appendage (LAA) function represents regional atrial function. The aim of our study was to investigate the influence of RAP on left atrial regional function and to evaluate the reversibility of changes after termination of pacing in a canine model. Ei...
