Filter by:MITRADVANCE-HF is a prospective, randomized, parallel-controlled, open-label, multicentre study trial enrolling patients with SMR and advanced HF on maximally tolerated standard of care therapies for HF according to the most recent guidelines. Enrolled patients will be randomly assigned, in a 1:1 ratio, to a device arm consisting of MitraClip therapy added to optimal medical therapy (OMT) or a control arm of OMT alone. Approximately 20 Italian high-volume centres will be involved. Enrolment duration will be of 24 months. Follow-up visit will be performed at 3, 6, and 12 months. Primary end-point was the absolute change in overall KCCQ summary score (KCCQ-OS) from baseline to 3 months follow-up.
Primary mitral regurgitation (MR) is the most common valvular disease in western countries. The MR mechanism is often related to a mitral valve prolapse (MVP) defined as a single or bi-leaflet prolapse of at least 2 mm beyond the long-axis mitral annular plane. In recent years, several studies have identified a subtype of MVP patients at higher risk of ventricular arrhythmias (VA) and sudden cardiac death (SCD). The presence of regional myocardial replacement fibrosis (RMRF) has been shown as a risk marker of arrhythmic events (VA and SCD) in patients with MVP. RMRF can be identified using cardiac magnetic resonance (CMR) imaging with late gadolinium enhancement (LGE+). In these patients, fibrosis was found in the basal inferolateral myocardium and at the level of papillary muscles (PMs). This fibrosis is developed beyond the volume overload related to the MVP. It is probably linked to the mechanical stretch acting upon the valve and the neighboring left ventricle (LV) myocardium. RMRF is associated with a high degree of MR, with specific features of mitral valve apparatus (bi-leaflet prolapse with marked leaflet redundancy, mitral annulus abnormalities (i.e. Mitral-Annular Disjunction)), and more dilated LV. It is also independently associated with the occurrence of cardiovascular events. Mitral valve repair (MVr) is the gold standard treatment for primary Mitral Regurgitation. Very little data concerning the impact of preoperative RMRF on mitral valve surgery outcomes is available, and the impact of myocardial fibrosis on the postoperative left ventricle remodeling has not been studied so far. No previous study compares preoperative and postoperative fibrosis evolution. Thus, no data exists regarding the postoperative evolution of this fibrosis and its relationship with ventricular arrhythmic risk after valve surgery. Small observational studies have suggested that mitral valve surgery did not reduce the risk of ventricular arrhythmias in patients with bileaflet MVP. Finally, the mechanisms involved in the development of regional myocardial replacement fibrosis within the left ventricle myocardium during the natural history of MVP cannot be understood with current standard medical imaging tools. Numerical simulation technologies provide an innovative and in-vivo approach to assess the physical and pathological mechanisms causing this fibrosis. They can also be used to assess the changes in mitral valve and myocardium dynamics after surgical mitral valve repair procedures. A large consortium, involving physicians and scientists, has been created to address these questions to fulfil our objectives over a 4 year period (SIMR project).
this research is based on the hypothesis that the measurement of the ratio of mean arterial pressure to mean left atrium pressure and of its evolution during the procedure, would make it possible to assess the immediate success of the procedure by supplementing the results of the ultrasound. The main objective of this research is to define the percentage of improvement in the mean arterial pressure / mean left atrium pressure ratio at the end of the procedure to validate the success of the MitraClip procedure.
The objective of this study is to evaluate the preliminary safety and effectiveness of the Cephea Mitral Valve System for the treatment of symptomatic patients with mitral valve disease (including mitral regurgitation, mitral stenosis and mixed mitral valve disease) in whom transcatheter therapy is deemed more appropriate than open heart surgery.
This is a prospective, multicenter, open-label, randomized trial comparing mitral valve (MV) transcatheter edge-to-edge repair (TEER) to surgical repair (1:1 ratio) in patients with primary, degenerative mitral regurgitation (MR). The trial will be conducted in the U.S., Canada, Germany and the United Kingdom, and is designed as a strategy trial. Thus, all devices legally marketed for TEER of primary degenerative MR in a particular country are eligible to be used in this trial.
A feasibility study to evaluate the effectiveness and safety of the SQ-Kyrin Transcatheter Edge-to-Edge Valve Repair System for the treatment of moderate-to-severe mitral regurgitation in patients with high surgical risk.
The objective of this study is to analyze the safety and efficacy of a novel device for minimally invasive mitral valve repair. Data of the early and intermediate postoperative period will be collected within routine clinical follow-up in order to assess morbidity and mortality as well as echocardiographic parameters.
The purpose of this clinical trial is to evaluate the effectiveness and safety of the transcatheter mitral valve repair system in the treatment of patients with moderate or above degenerative mitral regurgitation.
