Filter by: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.
Dilated cardiomyopathy (DCM) is characterized by a metabolic shift from fat to carbohydrates and failure to increase myocardial glucose uptake in response to workload increments. The investigators aimed at verifying whether this pattern is influenced by the presence of abnormal glucose tolerance (AGT).
The goal of this protocol is to obtain information from individuals with cardiomyopathy and from their families in order to elucidate the molecular genetics of this disorder. This will provide the basis for future genetic counseling as well as contribute to elucidating the biology of normal and abnormal cardiac function.
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.
The objective of this extension study is to evaluate the safety and potential beneficial effects of the Algisyl-LVR™ device in patients with established heart failure secondary to a dilated cardiomyopathy. The results of this study will provide confirmatory evidence of the long-term safety and effectiveness of the Algisyl-LVR in patients with established heart failure.
The heart beat is controlled by electrical signals. Following a heart attack, part of the heart muscle dies and is later replaced by scar tissue. Within this area of scar, there often remain "channels" of surviving tissue still able to transmit electrical signals. However, it is well established that these "conduction channels" (CC) can form a short circuit around the scar, leading to electrical disturbances (arrhythmias) that are potentially life threatening. The commonest of these is ventricular tachycardia (VT), and is estimated to cause 300,000 deaths per year. One recognised treatment option of VT involves burning (ablation) these "conduction channels" (CC) within the scar. However, at present, the procedure is long and is far off 100% effective. Consequently, current best practice does not rely on treating the VT, but rather preventing it from causing sudden death - this is achieved with an Implantable Cardioverter Defibrillator (ICD), a device which can recognise when a patient is in VT and deliver an internal shock to restore the normal electrical conduction. Patients with defibrillators subsequently are subject to recurrent painful and debilitating shocks which, although lifesaving, significantly reduce their quality of life. The limitation with ablation at present is due to the difficulty in visualising these CC's. Investigators at Imperial College have created a novel electrogram visualisation program, Ripple Mapping (RM), which they have already found to be superior to currently used programmes in cases of arrhythmias in the upper chambers of the heart (the atria). During a retrospective study in patients with scar related VT following a heart attack, when ablation was delivered in areas associated with identified Ripple Mapping Conduction Channels, these patients remained free of VT recurrence for >2 year follow up interval. The study hypothesis is that Ripple Mapping can identify all conduction channels within scar tissue critical to the VT circuit, ablation of which will lead to long-term freedom from VT and ICD therapies. The investigators now aim to perform a prospective randomised study comparing Ripple Mapping guided VT ablation against conventional VT ablation.
Patients with Ischaemic and Dilated Cardiomyopathy, face an increased risk for Arrhythmic Sudden Cardiac Death. The purpose of this study is to estimate the performance of Modern Non-Invasive Indices and the performance of Programmed Ventricular Stimulation in Sudden Cardiac Death Prediction.
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.
