BACKGROUND: Mitral regurgitation is a heterogeneous disease. Determining which patients derive optimal outcomes from transcatheter edge-to-edge mitral valve repair (TMVR) remains challenging. We sought to determine whether baseline mitral valve anatomic characteristics are predictive of left atrial pressure (LAP) changes during TMVR with MitraClip. METHODS AND RESULTS: Consecutive patients with severe mitral regurgitation undergoing TMVR (n=112) underwent continuous intraprocedural LAP monitoring and retrospective echocardiographic analysis for specific mitral anatomic characteristics...

BACKGROUND: Percutaneous mitral valve repair (PMVR) is increasingly performed in patients with severe mitral regurgitation (MR). Post-procedural MR grading is challenging and an unsettled issue. We hypothesised that the direct planimetry of vena contracta area (VCA) by 3D-transoesophageal echocardiography allows quantifying post-procedural MR and implies further prognostic relevance missed by the usual ordinal scale (grade I-IV). METHODS: Based on a single-centre PMVR registry containing 102 patients, the association of VCA reduction and patients' functional capacity measured as six-minute walk distance (6 MW) was evaluated...

BACKGROUND: The safety and efficacy of deep sedation (DS) in MitraClip® procedures have been shown previously. However, clinical experience demonstrates that in some patients DS is difficult to achieve. We hypothesize that some patient characteristics can predict difficult DS. METHODS: We prospectively analysed 69 patients undergoing MitraClip® procedures using DS. Application of DS was graded as simple (group 1) or difficult (group 2) depending on a cumulative score based on one point for each of the following criteria: decrease in oxygen saturation, retention of carbon dioxide, disruptive body movements, and the need for catecholamines...

Treatment for recurrent mitral regurgitation (MR) after MitraClip therapy remains a challenging issue. This study reports the efficacy of repeat MitraClip therapy for recurrent MR during the early phase after the index MitraClip procedure. We present a case series of four consecutive patients who underwent repeat MitraClip procedures for severe recurrent MR during the early phase. Partial clip detachment (PCD) was the suspected cause of recurrent MR in these cases. All patients received additional clip(s). PCD could be stabilized and MR grade improved in all cases compared with that before the second procedure...

OBJECTIVES: Transcatheter approaches in heart valve disease became tremendously important and are currently established in the aortic position, but transcatheter tricuspid repair is still in its beginning and remains challenging. Replicating the surgical edge-to-edge technique, for example, with the MitraClip System (Abbott Vascular, Santa Clara, Calif), represents a promising option and has been reported successfully in small numbers of cases. However, up to now, few data considering the edge-to-edge technique as a transcatheter approach are available...

BACKGROUND: Postprocedural mitral stenosis (MS) is a main limitation for MitraClip™ (Abbot Vascular, Inc., Santa Clara, CA, USA) procedure. The purpose of this study was to detect the preprocedural predictors of high transmitral pressure gradient (TMPG) after MitraClip™ implantation, which indicated postprocedural mitral stenosis (MS). METHODS: We studied 79 patients who were implanted with MitraClip™ in our institute. Before the procedure, mitral valve orifice area (MVOA), and anterior-posterior (AP) and medial-lateral (ML) mitral annular diameters were measured at diastole using three-dimensional (3D) transesophageal echocardiography (TEE) data set...

Symptomatic severe tricuspid regurgitation (TR), if untreated, carries a dismal prognosis. These patients are at very high risk for surgical repair or replacement and transcatheter options to treat TR are emerging. More than 300 transcatheter tricuspid repairs with the MitraClip system have been performed worldwide with promising results. The TriClip system, with the MitraClip NT delivered via a dedicated tricuspid steerable guide catheter, is currently under investigation. This article describes the step-by-step technique on using the MitraClip system to perform transcatheter tricuspid repair using echocardiographic and fluoroscopic guidance...

Transcatheter valve procedures are wide-spreading techniques for the treatment of heart valves pathologies. In case of implantation failure, the transcatheter device often needs to be removed. This procedure, which can alter the biological structure integrity, can limit the option available for the subsequent traditional surgery. One of the most popular devices for transcatheter mitral valve repair is the MitraClip system. In this work, we describe 2 different techniques for the surgical removal of MitraClip...
