Filter by:To study echocardiography splay sign in mitral regurgitation and its association with mitral regurgitation severity and doppler band artifact ('seagull cry').
No previous study has evaluated the effectiveness of transcatheter edge-to-edge mitral valve repair (TEER) in patients with ATTR-associated cardiomyopathy (ATTR-CM) and significant mitral regurgitation, as this specific patient population was specifically excluded from previous large TEER trials. From a pathophysiological perspective, effective treatment of significant regurgitant volume and consecutive improvement of forward volume appears highly desirable in a condition with intrinsically low output. However, whether this translates into improved functional capacity, better quality of life, and better clinical outcomes compared to conservative heart failure management alone remains to be investigated.
The study is aimed to assess the safety and feasibility of the Tioga TMVR System in treating patients with symptomatic MR (MR>=3+)
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..
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.
Mitral regurgitation is a pathology affecting the left atrioventricular valve that causes a volumetric and pressure overload in the left chambers due to the loss of unidirectionality normally guaranteed by the cardiac valve system. The gold standard for severe mitral regurgitation is currently mitral valve plastic surgery. Edge to edge, on the other hand, allows shorter CEC and aortic clamping times and does not require significant surgical experience in the field of mitral valve repair, therefore edge to edge could be an excellent strategy in patients suffering from mitral regurgitation caused by P2 prolapse when quadrangular resection cannot be performed. The main objective of the present study is to examine the medium to long-term outcomes (in terms of survival and plastic outcomes) of patients undergoing central edge-to-edge to treat posterior flap pathology (P2).
Mitral valve regurgitation is a pathology affecting the left atrioventricular valve, conditioning the loss of the normal unidirectionality of the atrioventricular flow and therefore volumetric and pressure overload of the left heart chambers. In industrialized countries, the most common etiology of mitral regurgitation is degenerative mitral disease. Mitral valve repair surgery represents the gold standard for the treatment of severe degenerative mitral regurgitation. The expected optimal result would be the absence of residual post-procedural mitral regurgitation, even if it is not uncommon to obtain a valve with residual regurgitation of a mild degree. In some cases, for various reasons (technical difficulties, long aortic clamping time, advanced age, high pre-operative surgical risk), a suboptimal result is accepted, i.e. a post-procedural residual mitral regurgitation of even a moderate degree ( 0, 1+, or 2+/4+). The aim of the present study is to evaluate the late clinical and echocardiographic implications of suboptimal mitral valve repair with a paired-data cohort study
Atrial functional mitral regurgitation (MR) is caused by annular dilatation and flattering associated with altered atria/annulus dynamics in patients with severely dilated left atrium and normal leaflets anatomy. Inadequate leaflets adaption is considered a mechanistic culprit as well. Prevalence of at least moderate atrial functional MR varies between 4.7% and 7% in patients with permanent and long standing persistent atrial fibrillation (AF) and is even higher in patients with Heart Failure with preserved Ejection Fraction (HFpEF). Unlike secondary MR in the setting of left ventricular disease, results of surgical treatment of severe atrial functional MR has remained largely unspoken. The aim of this study is to analyze short and mid-term results of isolated annuloplasty in patients with severe, symptomatic atrial functional MR, in comparission to a matched cohort of patients with secondary MR.
