OBJECTIVES: A single MitraClip implant is often considered enough to achieve adequate mitral regurgitation (MR) reduction. The aim of this study was to compare MR recurrence in patients with an initial optimal result treated with a single clip versus those treated with two clips. METHODS: From October 2008 to May 2016, 322 patients were treated with the MitraClip procedure at our institution. We retrospectively selected all patients treated for functional MR (FMR) and degenerative MR (DMR) aetiologies with residual MR ≤1+, excluding patients who required >2 clips...

BACKGROUND: Surgical mitral valve repair is the gold standard for treatment of mitral regurgitation. Recently, the transcatheter treatment of mitral regurgitation with the MitraClip(®) device (Abbot Vascular Structural Heart, Menlo Park, CA) has demonstrated promising results in treating patients not amenable for surgical correction of mitral valve regurgitation. Most patients reported in the literature requiring surgical bailout after MitraClip treatment presented with residual or recurrent mitral valve regurgitation...

There is a lack of specific tools for risk stratification in patients who undergo MitraClip implantation. We aimed at combining preprocedural variables with prognostic impact into a specific risk model for the prediction of 1-year mortality in patients undergoing MitraClip implantation. A total of 311 consecutive patients who underwent MitraClip implantation were included. A lasso-penalized Cox-proportional hazard regression model was used to identify independent predictors of 1-year all-cause mortality. A nomogram (GRASP [Getting Reduction of mitrAl inSufficiency by Percutaneous clip implantation] nomogram) was obtained from the Cox model...

BACKGROUND: Limited evidence is available about MitraClip therapy in patients with acute mitral regurgitation (MR) complicating myocardial infarction (MI). METHODS AND RESULTS: Among 80 consecutive patients undergoing MitraClip treatment, 5 (6.3%) had been admitted for acute MI complicated by severe MR. Mean age was 73±6years and 3 were males. At the time of admission they were in cardiogenic shock (80%) or pulmonary oedema (20%), with severe MR, left ventricular dysfunction and pulmonary hypertension...

BACKGROUND: Successful percutaneous mitral valve repair (PMVR) in patients with severe mitral regurgitation (MR) causes changes in hemodynamics. Echocardiographic calculation of cardiac output (CO) has not been evaluated in the setting of PMVR, so far. Here we evaluated hemodynamics before and after PMVR with the MitraClip system using pulmonary artery catheterization, transthoracic (TTE) and transesophageal (TEE) echocardiography. METHODS: 101 patients with severe MR not eligible for conventional surgery underwent PMVR...

AIMS: The aim of this study was to investigate the procedural feasibility and short-term durability of the transcatheter tricuspid valve edge-to-edge repair technique in highly symptomatic patients with severe tricuspid regurgitation (TR). METHODS AND RESULTS: Eighteen consecutive patients suffering from severe right-sided heart failure (NYHA Class III-IV), primarily due to moderate to severe tricuspid regurgitation, were included in the study. Applying a modified steering technique for the clip delivery system, six patients were treated for isolated severe TR, while 12 patients were treated for moderate to severe TR and concomitant severe mitral regurgitation...

The goal of MitraClip therapy is to achieve mitral regurgitation reduction without iatrogenic creation of clinically significant MS. In some series, up to 35% of patients are left with mild MS. There are many contributors to the final transmitral gradient achieved in patients undergoing MitraClip therapy. Additionally, there are many modalities used for the intraprocedural assessment of MS with no one modality considered to be the benchmark. We herein describe a case which illustrates the dynamic nature of clip-leaflet interaction, and review intraprocedural techniques for invasively and noninvasively assessing MS...

BACKGROUND/OBJECTIVES: The acute and long-term effects of interventional edge-to-edge repair on the mitral valve (MV) geometry are unclear. We sought to assess MV-annular geometry and the association of changes in MV-diameters with functional response one year after MitraClip implantation. METHODS: Consecutive patients (n=84; age 81.2±8.3years, logistic EuroSCORE 21.7±17.9%) with symptomatic moderate-to-severe mitral regurgitation (MR) underwent MitraClip-procedure...

A 73-year-old male received a percutaneous mitral valve repair with a MitraClip to treat severe (grade IV) symptomatic mitral regurgitation (MR). The MitraClip® procedure reduced the MR to grade I, but the patient died 14 days post-procedurally due to a pneumosepsis. Histological analysis of the MitraClip mesh covering showed a chronic inflammatory reaction with an abundance of multinucleated giant cells. Remarkably, signs of early onset clip-coverage were found, indicated by the presence of a few scattered myofibroblasts...

Transesophageal echocardiography (TEE) assessment after MitraClip implantation is limited by unequal orifices and jets, eccentric regurgitation, and the acute change of the annulus geometry. Periprocedural real-time invasive hemodynamic assessment of the mitral valve function requires experience in hemodynamic monitoring interpretation. However, it provides excellent accuracy as it does not take into account the changes of the mitral apparatus geometry and jet direction after MitraClip placement. While we seek to expand indications of Mitraclip to other patient subgroups, we should consider routine ancillary invasive hemodynamic assessment, in order to optimize our understanding, procedural results...

In literature, there are limited data comparing ischemic mitral regurgitation (I-MR) versus nonischemic MR regarding outcomes after percutaneous "edge-to-edge" repair. We aimed to describe the early and 12-month results after MitraClip device implantation regarding the 2 etiologies. From January 2011 to December 2012, the Transcatheter Valve Treatment Sentinel Pilot Registry included 452 patients with MR who underwent MitraClip procedure in 25 centers across Europe. The prevalent etiology was I-MR (235 patients, 52...

BACKGROUND: It is believed that most of thrombi form in the left atrial appendage (LAA)before they emboli. Different surgical and percutaneouse approaches were suggested to manage the LAA. In this study we are evaluating the safety of clipping the LAA via minithoractotomy approach. METHOD: All consecutive patients who had minimally invasive mitral valve surgery with concomitant LAA clipping between December 2012 and February 2014 were included in the study. LAA exclusion was performed using AtriClip® LAA Exclusion System (Cincinnati, Ohio, AtriCure®)...

REVIEW
Takahiro Shiota
Catheter-based treatment of valvular heart disease, such as transvalvular aortic valve replacement (TAVR) or mitral clip procedure, has been increasingly accepted as a treatment choice for the past several years. Such new treatment options have been changing the management of patients with valvular heart disease drastically while socio-economic factors regarding their application need to be taken into consideration. The use of echocardiography, including transesophageal echocardiography (TEE), for such catheter-based treatments is essential for the success of the procedures...

Mitraclip(®) implantation is widely used as a valid alternative to conventional open-chest surgery in high-risk patients with severe mitral valve (MV) regurgitation. Although effective in reducing mitral regurgitation (MR) in the majority of cases, the clip implantation produces a double-orifice area that can result in altered MV biomechanics, particularly in term of hemodynamics and mechanical stress distribution on the leaflets. In this scenario, we combined the consistency of in vitro experimental platforms with the versatility of numerical simulations to investigate clip impact on MV functioning...

Edge to edge transcatheter mitral valve repair with MitraClip (Abbott Vascular, Menlo Park, CA) is increasing for high-risk surgical patients with significant mitral regurgitation. Patients with congenitally corrected transposition of the great arteries (CCTGA) presenting with tricuspid valve regurgitation of a systemic right ventricle may represent particularly challenging candidates for MitraClip given their anatomy. We report the case of a 67-year-old gentleman with CCTGA and severe tricuspid regurgitation who was referred for MitraClip implantation after heart team consensus...
