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...

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...

Echocardiography continues to be the most effective imaging tool for the diagnosis and follow-up of mitral valve disease. This review addresses the use of transthoracic echocardiography and transesophageal echocardiography in the planning and guidance of transcatheter mitral valve therapies. Many of the echo-imaging guidance techniques are applicable to transcatheter intervention as a whole. However, given that the MitraClip is the only device approved for mitral regurgitation at present, specific attention is paid to this procedure, with additional focus on the guidance of noncentral repair...

An 84-year-old man with cardial senile amyloidosis and severe tricuspid regurgitation was referred for right sided heart failure symptoms. The patient was scheduled for a percutaneous treatment due to the prohibitive risk of surgery. Two MitraClips were implanted using a transjugular approach with successful echocardiographic and clinical results. This case shows the rational of the procedural with a bicuspidalization of the valve demonstrated at the three dimensional transesophageal echocardiography.

INTRODUCTION: Intraprocedural assessment of mitral regurgitation (MR) is a challenging issue during the MitraClip procedure, which might influence not only the position but also the number of MitraClips implanted. Though transesophageal echocardiography (TEE) is the predominant tool used during the MitraClip procedure, MR assessment might be facilitated by a multimodality approach including continuous and simultaneous determination of left atrial and left ventricular (LV) pressure. METHODS: 86 consecutive patients (76...

Percutaneous edge-to-edge mitral valve repair with the MitraClip device has been shown to be a safe and effective procedure in selected patients with moderate-to-severe mitral regurgitation. Two-dimensional transesophageal echocardiography (2D TEE) is the primary imaging modality for guidance of the procedure. Real-time three-dimensional (3D) TEE has recently been used as additional imaging modality during the MitraClip procedure. In comparison with 2D TEE, 3D TEE provides additional information in several steps of the procedure, including precise positioning of the clip delivery system into the left atrium, correct alignment of the clip arms perpendicular to the coaptation line and confirmation of the correct grasping location...

OBJECTIVES: We evaluated intracardiac echocardiography (ICE) for adjunctively guiding the MitraClip procedure in patients with prior surgical rings. BACKGROUND: Transesophageal echocardiography (TEE) is the standard imaging modality used to guide the MitraClip procedure (Abbott Vascular, CA). However, in patients with post-surgical anatomy, clear imaging of the mitral valve leaflets may be complex because of shadowing from the surgical ring. In these patients, TEE may be suboptimal for guiding the procedure, even using three-dimensional imaging...

BACKGROUND: Echocardiographic quantification of mitral regurgitation (MR) can be challenging if the valve geometry is significantly altered. Our aim was to compare the quantification of MR by the recently developed real time three-dimensional (3D) volume color flow Doppler (RT-VCFD) method to the conventional two-dimensional (2D) echocardiographic methods during the MitraClip procedure. METHODS: Twenty-seven patients (mean age 76 ± 8 years, 56% male) were prospectively enrolled and severity of MR was assessed before and after the MitraClip procedure in the operating room by 3 different methods: (1) by integrative visual approach by transesophageal echocardiography, (2) by transthoracic 2D pulsed-wave Doppler-based calculation of aortic stroke volumes (SV) and mitral inflow allowing calculation of regurgitant volume, and (3) by transthoracic 3D RT-VCFD-based calculation of regurgitant volume...

BACKGROUND: MitraClip® therapy is an alternative to conventional surgery. The aim was to characterize the mitral annular geometry pre- and postrepair with the MitraClip® taking into account the regurgitation mechanism. METHODS: We retrospectively collected pre- and postprocedural transesophageal echocardiography data in 46 patients. Patients were categorized as having isolated degenerative (DMR, n = 18), isolated functional (FMR, n = 9) or a combination of both functional and degenerative mitral regurgitation (MMR, n = 19)...

Percutaneous edge-to-edge repair with the MitraClip system has emerged as a new therapeutic option for moderate to severe or severe mitral regurgitation (MR). Several clinical studies demonstrated its safety and efficacy in patients with both degenerative and functional MR. Based on these results, this catheter-based therapy received CE mark for both etiologies of MR in 2008, and approval from United States (US) Food and Drug Administration for degenerative MR with prohibited surgical risk in 2013. To date, around 12,000 patients underwent the MitraClip therapy worldwide...

BACKGROUND: Transcatheter mitral valve repair (TMVR) is a treatment option in patients with symptomatic functional or degenerative mitral regurgitation (DMR) at high surgical risk. The acute effect of MitraClip procedure on mitral valve (MV) annular geometry and its relation to functional outcomes is unclear. We sought to assess immediate effect of TMVR on MV annular geometry with 3-dimensional (3D) transesophageal echocardiography and the association of MV diameter reduction with functional response after 6 months...

The percutaneous mitral valve (MV) repair procedure performed with the MitraClip delivery system is increasingly used to treat severe mitral regurgitation in high-risk patients. The treatment involves percutaneous insertion and positioning of a clip between the MV leaflets. Transesophageal echocardiography (TEE) plays a key role in the procedure by providing information regarding clip navigation, clip alignment to the MV coaptation line, transmitral advancement of the system, leaflet grasping, confirmation of valve tissue catching, and assessment of the final result...
