Filter by:A phase 1 prospective study to determine the procedural feasibility and safety and preliminary efficacy of intracoronary infusion of cardiosphere-derived cells (CDCs) in patients with dilated cardiomyopathy.
Up to 72 healthy volunteers will be given a single dose of MYK-491 or placebo and be monitored for safety and tolerability over a 7 day period.
First, investigators must determine the physiological standards across age classes of myocardial stiffness estimated by Elastography in ultrafast (estimated right ventricular stiffness [VD] and left ventricular [LV]). This will be done in groups of children without heart condition, age group (10 children per group, four age groups [0-1mois, 1 month-1 year 1 year-5 years, 5 years-15years]). Secondly, investigators will evaluate myocardial stiffness Elastography (RV and LV) on different groups of children (same age group) with cardiomyopathy and examine correlations with the conventional parameters of systolic and diastolic function of both ventricles and with myocardial strain values. The total population of the study will be 120 children (40 healthy, 80 patients).
The bone marrow mononuclear cell fraction has been used as therapy after myocardial infarction and in dilated cardiomyopathy in adults. The absence of adult co-morbidities may enhance the potential effectiveness of pediatric stem cells.This study is a randomized, crossover, placebo controlled pilot study to primarily determine the safety and feasibility of stem cell intracoronary therapy in children. Secondary end points are MRI measurements and NTproBNP. Ten children (mean age 7.2 years, range 2.2-14.1, 6 male) with dilated cardiomyopathy (NYHA/ Ross Classification 2-4) will be recruited. Bone marrow aspiration MRI and cell injection are performed under the same anaesthetic. Patients will be crossed over at 6 months.
The goal of REMEDIUM project is to develop personalized stem cell therapy for patients with chronic heart failure due to dilated cardiomyopathy (DCM). The main focus of the project is (1) on repetitive administration of cell therapy that would allow for long-lasting improvements in heart function and outcome in this patient population. In parallel, the investigators aim to (2) develop a standardized patient-specific stem cell product that could be cryopreserved and stored in a stem cell bank for prolonged time periods, and used for therapeutic application when clinically indicated. By using a unique multimodality imaging platform, the goal of this project is also to (3) define standardized clinical criteria that would serve as a guideline for evaluation of the effects of stem cell therapy in future clinical trials and everyday clinical settings. Finally, to improve the clinical implementation of cell therapy,the investigators aim to (4) develop a stem cell delivery technique that could be used to treat both left and right and ventricular failure and could be implemented in a standardized fashion designed for a widespread clinical use.
This study is a descriptive study to investigate clinical and genetic features of dilated cardiomyopathy (DCM) patients and their relatives. 109 probands with DCM have been clinically characterized with clinical examinations including ECG and echocardiography, and furthermore they have had next generation sequencing (NGS) of 42 known DCM genes, and 34 candidate genes. The probands were consequtively included in the study and 59 had undergone heart transplantation (HTx) upon inclusion. of these patients underwent heart transplantation. The data from NGS is validated by Sanger sequencing. In this study we will examine the relatives to the 109 index patients by genetic and clinical cascade screening including advanced echocardiography including 3D volume measurements and speckle-tracking (GLS). Genetic investigations of relatives will be performed if a disease-associated mutation is identifed in the proband. Approximately 480 clinical examinations will be performed this way to be able to: 1a. Investigate the frequency of familial types of DCM 1b. To investigate the yield of genetic and clinical cascade screening 2. To describe genotype phenotype correlations 3. To investigate if there are subtle changes in the heart in genopositive individuals which do not meet the conventional diagnostic criteria evaluated by advanced echocardiography.
Recent data suggest that areas of fibrosis and hibernating myocardium develop in patients with non ischemic dilated cardiomyopathy. Ranolazine is a new drug, developed to releave symptoms of angina in patients with stable coronary disease that is not suitable for surgical or percutaneous revascularization. It has been shown that in patients with stable coronary disease Ranolazine improves myocardial perfusion as shown with myocardial nuclear imaging. The aim of this trial is to evaluate effects of ranolazine on myocardial perfusion in patients with dilated cardiomyopathy.
This study aims to determine the effect of Coenzyme Q10 supplementation on conventional therapy of children with heart failure due to idiopathic dilated cardiomyopathy.
The "EUropean Comparative Effectiveness Research to assess the use of primary prophylacTic Implantable Cardioverter Defibrillators (EU-CERT-ICD)" is a modular research project to study the effectiveness of prophylactic ICDs in a prospective study, a retrospective registry, and meta-analyses of existing evidence on the subject.
Detecting abnormalities in the left ventricular mechanical and hemodynamic response to the stress of exercise may offer early diagnostic indicators in patients suffering from valvular disease such as mitral regurgitation. Ultrasound-based imaging methods have been gaining importance in providing prognosis among those patients. However, decreased signal to noise ratio in the images and increased motion-related artifacts during exercise stress echocardiography have been reported, with a lack of reproducibility of results and a the limitation of its availability only in reference centers. In our laboratory, we are able to perform supine bicycle exercise MRI (1.5 T) using the Lode ergometer mounted on the far end of the patient table, previously described in healthy volunteers. The first aim of our study is to demonstrate the safety and the feasibility of our MRI protocol in selected patients with asymptomatic severe organic mitral regurgitation, to assess left ventricular volumes and function, and regurgitant volume in comparison to exercise cardiac echography. Besides, few recent studies sustain the relevance of novel markers of central aortic function (compliance, distensibility and pulse wave velocity) assessed by noninvasive MRI to explore vascular aging. In monogenic connective tissue diseases, altered arterial stiffness is the premature signature of the disease in asymptomatic patients. Noninvasive evaluation of aortic stiffness would be useful for risk assessment and preventive follow-up strategies in young asymptomatic relatives of subjects with aortic inherited diseases, such as syndromic and non-syndromic familial forms of thoracic aortic aneurysm and /or dissection. Furthermore, this technique should be able to evaluate the effect of drugs on aortic stiffness change in trials, before and after drug therapy, more relevant than the classic change in aortic diameter measurement. The second aim of our study is 1) to provide the sensibility of our MRI protocol to estimate local and regional heterogeneity in aortic functional parameters (distensibility, compliance and PWV) 2) to evaluate the predictive value of these regional aortic parameters assessed by MRI to diagnose and to stratify the aortopathy related to presymptomatic Marfan patients and to bicuspid aortic valve in young adults, in comparison to carotids-femoral pulse wave velocity estimation by applanation tonometry.
