View clinical trials related to Mitral Valve Insufficiency.
Filter by:Mitral valve disease is the most common structure heart disease, and surgical valve replacement is an important treatment for severe mitral valve disease. There are 2 types of valve often been used, mechanical or biological protheses valves. Mechanical valve requires lifelong use of anticoagulants and take the risk of bleeding through all lifetime, but bioprotheses valve do not..

Participant will under go: - Baseline echocardiography - Cpex Echocardiography - Blood test: BNP - 1 year follow up Echocardiography Participants will be stratified into three subgroups: - Atrial Functional MR - Atrial Functional TR - Mixed MR & TR

Acquired heart diseases continue to remain one of the most common causes of cardiac mortality and morbidity. In the Russian Federation, open surgery treatment of acquired valvular heart diseases (AVHD) is performed in more than 40 regions by specialists from 92 healthcare organizations. Treating aortic or mitral valve disease using the "UniLine" biological prosthesis is expected to improve survival rates. Supposedly, in vivo the "UniLine" biological prosthesis will show optimal hemodynamic characteristics and high resistance to structural valve degeneration and infectious damage, thus lowering the risk of dysfunction. Moreover, the risk of repeated intervention due to dysfunction of the "UniLine" bioprosthesis should not exceed the risk of the primary implantation. Supposedly, in the case of dysfunction of "UniLine" bioprosthesis it would be possible to perform repeated replacement using valve-in-valve technique. The aim of the study is to assess the effectiveness, safety, durability of the "UniLine" epoxy-treated prosthesis and the long-term outcome of the treatment of isolated mitral and aortic valve diseases using this prosthesis. In accordance with the objectives and hypothesis, the following data will be analyzed: actuarial and linear survival rates (general and cardiac), non-lethal prosthesis-associated complications, prosthetic dysfunction and repeated interventions. Moreover, in vivo hemodynamic parameters of the prosthesis will be assessed: the area of the effective opening surface, peak and mean gradient of pressure and blood flow velocity. The study will be conducted at the Research Institute of Complex Issues of Cardiovascular Diseases. Study protocol received sponsorship approval and approval by Local Ethics Committee of the Research Institute and Research Coordinating Committee. The study will enroll patients who underwent isolated mitral or aortic valve replacement; transthoracic echocardiography will be conducted in all patients available for in-person visit.
The Munich Trascatheter Mitral Valve System is intended for beating heart, mitral valve replacement in patients with a diseased, damaged, or malfunctioning mitral valve. Access is provided through the Femoral Vein and transseptal approach by means of a 27Fr catheter. The bioprosthetic valve consists of a self-expanding, tri-leaflet, dry bovine-pericardial valve. The dry tissue allows the valve to be conveniently pre-loaded. The valve is available in three sizes and has been designed to reduce the complexity of implantation in comparison to other TMVR systems.
Comparsion of the current two available TEER systems, the MitraClip with the PASCAL repair system in terms of their effectiveness and safety in patients with degenerative mitral regurgitation (DMR) and in patients with functional regurgitation (FMR), who were referred for an interventional therapy by the heart team due to a high surgical risk profile.
Septal myectomy is performed in selected cases to treat patients with hypertrophic obstructive cardiomyopathy (HOCM). The mechanism that causes obstruction involves both the outflow tract itself and the mitral apparatus, with the appearance of mitral regurgitation (MR) by SAM (Systolic Anterior Motion). When the interventricular septum is not particularly thick, isolated myectomy may not be sufficient to eliminate the SAM; in these cases the concomitant treatment of the mitral valve is considered. Different approaches have been proposed: mitral replacement with prosthesis, plication or lengthening of the anterior leaflet or the edge-to-edge (EE) technique. In addition, a small proportion of patients with HOCM may have MR from organic valve abnormalities, requiring specific treatment. Currently, there are few studies in the literature aimed at determining the role of EE in the context of HOCM; most of these studies are characterized by short follow-up or by the scarcity of echocardiographic data. The aim of the present study is to evaluate the long-term outcomes of EE associated with septal myectomy in patients with CMIO, both from a clinical point of view and by reporting echocardiographic data.
A significant reduction in the incidence of CV death or hospitalization for HF has been observed in randomized trials investigating the CV benefit of Dapagliflozin. Mechanistic investigations are required to interpret the positive clinical effects of Dapagliflozin on heart structure and valvular regurgitation.
The goal of this clinical trial is to learn about the effect of dapagliflozin on reducing the degree of mitral regurgitation and myocardial fibrosis in patients with functional mitral regurgitation (FMR) of more than moderate and left ventricular ejection fraction (LVEF) more than 40%. The main question[s] it aims to answer are: - For FMR patients with EF>40%, whether adding SGLT2 to guideline directed medical therapy (GDMT) can reduce MR degree and myocardial fibrosis, as well as improve patient's cardio-pulmonary function and quality of life is unknown. - For FMR patients with EF>40%, whether adding SGLT2 to GDMT can decelerate the progression of FMR to end-stage heart failure, reduce the demand for percutaneous mitral valve repair and improve the prognosis is unknown. Participants in dapagliflozin arm will add dapagliflozin of 10 mg/d orally for 6 months on the basis of regular GDMT for FMR. Researchers will compare the dapagliflozin arm to the GDMT arm who only accept the regular GDMT to see if the effective regurgitant orifice area was decreased. The primary endpoint was the effective regurgitant orifice area(EROA) change from baseline to 6 months. The secondary endpoints include the cardiac magnetic resonance assessment of myocardial fibrosis, the N-terminal fragment of the pro brain natriuretic peptides(NT-pro BNP), maximal exercise capacity by cardiopulmonary exercise testing, distance in the 6 minutes walking test, Kansas City cardiomyopathy questionnaire and Cardiovascular events.
The objective of the CAMERA-Pilot trial is to generate a hypothesis for a proper randomized controlled clinical endpoint trial to show the noninferiority of restoration and maintenance of sinus rhythm (via catheter ablation [CA] of AF) vs. mitral transcatheter edge-to-edge repair (M-TEER) in patients with AF and concomitant FMR. Patients will be stratified into ventricular FMR with atrial component and atrial FMR.
