Filter by:The purpose of this study is to conduct a clinical investigation of the Foldax Tria Mitral Valve to collect evidence on the device's safety and performance.
Quantification of residual mitral regurgitation (MR) after MitraClip may be challenging. Quantitative methods for severity assessment may be inaccurate and recent recommendations suggest an assessment of changes in both hemodynamic and echocardiographic parameters, but an established prospectively validated approach is still lacking.
This study will establish the safety and effectiveness of the Edwards SAPIEN X4 Transcatheter Heart Valve (THV) in subjects who are at high or greater surgical risk with a failing mitral surgical bioprosthetic valve or a failing native mitral valve with an annuloplasty ring.
To investigate the efficacy and safety of transcatheter mitral valve edge-to-edge repair (TEER) for severe degenerative mitral regurgitation (DMR) patients of low to intermediate surgery risk.
This study will assess hemodynamic changes induced after spinal anesthesia by evaluating vasopressor inotropic requirements and variations in echocardiographic parameters in patients having severe aortic stenosis or severe mitral regurgitation undergoing aortic or mitral valve replacement surgery.
To study echocardiography splay sign in mitral regurgitation and its association with mitral regurgitation severity and doppler band artifact ('seagull cry').
An early feasibility study to evaluate the safety and feasibility of the MRace Implant and Delivery System to treat severe mitral regurgitation and to gather preliminary data on its performance thereby providing guidance for future clinical development. The study is a single-arm registry with the last follow-up visit at 5 years post-intervention. The study will enroll up to 10 patients at one (1) center in Brazil.
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 goal of this observational study is to compare the safety and effectiveness of a modified drug therapy with traditional drug therapy in pediatric patients after mitral repair. The main questions it aims to answer are: - Can a modified drug therapy improve both left ventricular and mitral valve function in pediatric patients after mitral repair? - Can the adverse drug reactions caused by the modified drug therapy be non-inferior (clinically acceptable) to those of the traditional drug therapy? Participants will be assigned to either the Modified Drug Therapy Group (comprising angiotensin-converting enzyme inhibitor (ACE-I), beta-blockers, diuretics, potassium supplements, and spironolactone) or the Traditional Drug Therapy Group (diuretics and potassium supplements) based on personal preferences and clinical assessments by their attending physicians. They will undergo a 6-months course of medication. Additionally, echocardiography, electrocardiograms, complete blood counts, biochemical tests, and measurements of N-terminal pro-brain natriuretic peptide (NT-proBNP) were conducted before the initiation of medication therapy and at 1 month, 3 months, and 6 months after treatment commencement. Researchers will compare the Modified Drug Therapy Group and the Traditional Drug Therapy Group to see if the recurrence rate of moderate to severe mitral valve regurgitation, as assessed by echocardiography after 6 months of treatment, is lower in the former than in the latter.
The study is aimed to assess the safety and feasibility of the Tioga TMVR System in treating patients with symptomatic MR (MR>=3+)
