The MitraClip System is extensively used in high‐risk patients with symptomatic severe mitral regurgitation (MR). Some studies have identified complications associated with use of the MitraClip. We report the case of a 91‐year‐old woman with severe MR of a prolapsed posterior commissure. Two weeks after using the MitraClip, she developed hemolytic anemia. She was conservatively treated with blood transfusion and medical treatment; fortunately, her general condition did not deteriorate during the follow‐up period. To the best of our knowledge, this is the first report of hemolytic anemia after MitraClip implantation. 相似文献

Although transcatheter mitral valve edge-to-edge repair (TEER) has been widely used for non-central degenerative mitral regurgitation (MR), few reports have described therapeutic strategies for commissure prolapse. Furthermore, no standard approach for TEER for commissure has established. Thus, we categorized various grasping strategies into three patterns, and proposed a promising systematic strategy to observe three possible grasping patterns for identifying appropriate grasping target. Here, we report a successful TEER case of isolated posterior commissure prolapse in which we used a systematic approach. 相似文献

二尖瓣反流(Mitral valve regurgitation,MR)逐渐成为心脏瓣膜病中最常见的疾病之一。虽然外科手术在治疗MR中起到重要作用,但由于围手术期的风险过大、老年人基础情况较差等原因,许多患者禁忌外科手术。近年来,经导管治疗MR装置的出现,给治疗MR带来了新的选择,但同时也面临着许多挑战。本文综述了经导管治疗MR装置的技术特征及其临床试验的结果。 相似文献

Congenital heart disease patients, specifically with unbalanced atrioventricular septal defects and common atrioventricular valves requiring single ventricle palliation, have substantial morbidity and mortality. Atrioventricular valve regurgitation (AVVR) is associated with poor outcomes in single ventricle patients, and many of them require surgical treatment of AVVR in their lifetimes. We describe a unique case of transcatheter edge‐to‐edge valve repair using the MitraClip system (Abbott, Chicago, IL) in a single ventricle patient with severe common AVVR. 相似文献

Introduction
Percutaneous mitral valve repair (PMVR) using MitraClip system has emerged as a therapeutic option for patients with functional severe mitral regurgitation (FMR) at prohibitive risk for surgery. In this setting, the echocardiographic assessment of FMR severity is challenging because the traditional echocardiographic methods have important limitations. The aim of this study was to assess the accuracy and reliability of a simple Doppler index, the mitral/aortic flow velocity integral ratio (MAVIR), to evaluate residual FMR severity after PMVR.Methods
Eighty‐five heart failure patients with functional MR and LV dysfunction (LVEF ≤ 40%) were included. FMR was quantified on the basis of traditional quantitative parameters of MR severity. MAVIR was expressed as the ratio of mitral and aortic time velocity integral (TVI) values. According to MR severity, 25 patients underwent MC implantation and at 6 months a complete echocardiographic follow‐up was performed.Results
A significant linear relationship was found between MAVIR and both VC and EROA. A MAVIR ≥1.02 identified pts with severe MR with a sensitivity of 86.7% and a specificity of 90.9%. At the 6 months echocardiographic follow‐up after the MitraClip implantation, we observed a significant reduction of LAVI, LVED and LVES volume, while LVEF improved. Furthermore, MAVIR significantly decreased its decrease showed a significant linear relationship with LAVI reduction.Conclusion
Our data show a close relationship between MAVIR and traditional indexes of MR severity in patients with FMR. This Doppler‐derived index seems applicable after PMVR where traditional echocardiographic index of MR severity shows significant limitations.13.

Recurrent flail leaflet represents an infrequent cause of recurrent mitral regurgitation after MitraClip. This report presents a case of recurrent severe MR due to a ruptured chorda tendineae after edge‐to‐edge repair. 相似文献

BackgroundTranscatheter mitral valve repair (TMVR) has shown to improve symptoms and functional capacity in patients with severe mitral valve regurgitation (MR). Novel device developments provide the technology to treat patients with complex anatomies and large coaptation gaps. Nevertheless, the question of superiority of one device remains unanswered. We aimed to compare the MitraClip XTR and MitraClip NTR system in a real world setting.HypothesisTMVR with the MitraClip XTR system is equally effective, but associated with a higher risk of leaflet injury.MethodsWe retrospectively analyzed peri‐procedural and mid‐term clinical and echocardiographic outcomes of 113 patients treated for severe MR between March 2018 and August 2019 at the University Hospital of Munich.ResultsPostprocedural MR reduction to ≤2+ was comparable in both groups (XTR: 96.1% vs. NTR: 97.6%, p = .38). There was a significant difference in a composite safety endpoint of periprocedural Major adverse cardiac and cerebrovascular events (MACCE) including leaflet injury between groups (XTR 14.6% vs. NTR 1.7%, 95% CI [2.7, 24.6], p = .012). After a median follow‐up of 8.5 (4.4, 14.0) months, durable reduction of MR was confirmed (XTR: in 91.9% vs. NTR: 96.8%, p = .31) and clinical and symptomatic improvement was comparable in both groups accordingly.ConclusionWhile efficacy was comparable in both treatment groups, patients treated with the MitraClip XTR systems showed more events of acute leaflet tear and single leaflet device attachment (SLDA). A detailed echocardiographic assessment should be done to identify risk candidates for acute leaflet injury. 相似文献
