NCT05988450
To verify the safety and effectiveness of transcatheter mitral valve clip delivery system and steerable guide catheter produced by Shanghai Shenqi Medical Technology Co., Ltd. in patients with moderate-severe (3 +) or severe (4 +) functional MR (functional MR) who still have symptoms after full treatment.
NCT05848102
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.
NCT04529928
The objective of this prospective, multi-center trial is to assess the effectiveness of the CARILLON Mitral Contour System in treating patients with moderate-to-severe atrial functional mitral regurgitation (aFMR)
NCT05677568
This is a retrospective and prospective, multi-center, post-market observational registry study. The primary objective of this post market registry is to continue to evaluate the long term safety and performance of the Carillon® Mitral Contour System® (CMCS) in a commercial (post market) setting.
NCT05606718
Functional mitral regurgitation (FMR) leads to various adverse outcomes. Cardiac remodeling (CR) and myocardial fibrosis (MF) are closely related to FMR, forming a vicious circle of CR-FMR-MF and resulting in the end-stage heart failure (HF). The optimal therapeutic strategies of FMR require to effectively break the vicious circle of CR-FMR-MF and still remain full of controversy, especially in the appropriate selection of patients suitable for transcatheter treatment. Regardless, adequate guideline-directed medical therapy (GDMT) is always the most important therapy of FMR. Currently GDMT for FMR included β-blockers, renin-angiotensin system (RAS) inhibitors and mineralocorticoid receptor antagonists (MRA). Dapagliflozin, a sodium-glucose cotransporter-2 inhibitor, have been proven to be effectively in reducing cardiovascular death and worsening HF in HF patients. However, there is still no evidence support the use of SGLT2i in FMR therapy due to the lack of relevant clinical trial. The DEFORM trial aims to assess the efficacy of dapagliflozin in reducing the extent of mitral regurgitation and myocardial fibrosis in FMR patients. DEFORM trial is a multi-center, prospective, randomized, parallel controlled, investigator-initiated trial enrolling a planned 98 FMR patients. Patients will be randomly assigned in a 1:1 ratio to either dapagliflozin 10mg once daily for 3 months or placebo. The primary outcome is the change in effective regurgitant orifice area (EROA) of mitral regurgitation measured by echocardiography. Secondary end-points include change change in regurgitant volume (RV), left ventricular end-systolic volume (LVESV), left ventricular end-diastolic volume (LVEDV) (echocardiography), change in NT-proBNP levels and occurrence of major adverse cardiac events (MACEs).
NCT05566340
Debates exist on the treatment of moderate functional mitral regurgitation (FMR) in patients undergoing aortic valve replacement (AVR) for aortic valve disease. This study aims to evaluate the left ventricular function, which was evaluated through global longitudinal strain, after isolated AVR and AVR + mitral valve repair (MVr) in this group of patients.
NCT04776798
It is stated that abnormal lower extremity posture and biomechanics are effective in the development and progression of Low Back Pain (LBP). Exercise, electrotherapy, insoles, and orthoses are used for the prevention and treatment of low back pain.The use of orthosis, insoles, and taping techniques stands out in the correction of foot posture and dysfunctions, which are stated to cause LBP. In studies examining the application of taping to improve foot posture and biomechanics, it is stated that taping is effective in improving foot posture and biomechanics in the short term. Biomechanical taping has been used in the treatment of musculoskeletal disorders in recent years. It is aimed to correct the impaired joint biomechanics by reducing the load on the joint, supporting strength, and providing movement modification.
NCT02520310
The objective of the study is to confirm the reproducibility of the evidence of safety and efficacy of AVJ-514 System technology in Japanese subjects who have been deemed difficult for mitral valve surgery by the local site heart team.
NCT02701972
The preclinical and clinical evidence of safety and efficacy with the BACE device (concept and feasibility) paved the way for the evaluation of the BACE device in this prospective, multi-center, single-arm, self-controlled study for safety and efficacy in the treatment of functional MR in a maximum of 60 adult subjects. The primary efficacy endpoint will be reduction of MR grade to 1+ or less from the baseline MR grade through the 6 month study period. Primary safety endpoint will be freedom from major device and surgery-related adverse events for the duration of the 6 month follow up period. Patients will be followed up to two years.
NCT02985268
At present, the optimal treatment strategy for heart failure patients and moderate-to-severe (3+) or severe (4+) mitral regurgitation with a class IIa recommendation for CRT is uncertain.Whether these patents should also be treated for functional mitral regurgitation or with CRT also remains unclear. We therefore propose a randomized 2x2 factorial design in this patient population to understand the the impact of both CRT and transcatheter mitral valve repair with the MitraClip on their functional status and quality of life.
NCT00947921
Functional Mitral regurgitation is a now well known entity due to tethering of the valve either mono-lateral, as happens in lateral myocardial infarction, or bilateral as happens in dilated cardiomyopathy. Treatment of this pathology, either conserving the valve and addressing regurgitation by mean of restrictive annuloplasty, or implanting a prosthesis remains controversial in terms of mid and long term benefit for the patient. The investigators propose a randomized controlled study to compare the efficacy of both technique in terms of mortality and freedom from reintervention.
NCT02471664
