Active clinical trials for "Cardiomyopathies"

Study to examine the safety and effectiveness of implanted skeletal muscle cells (cells removed from the thigh muscle) into scarred areas of heart muscle after heart attack.

This study aims to investigate the myocardial phenotype of patients with type 2 diabetes. From 2016-2019 the investigators recruited a cohort of 296 subjects with type 2 diabetes. All subjects underwent clinical examinations including a gadolinium contrast cardiac MRI. The current study is a clinical follow-up study of the subjects, thus, the investigators will invite all participants to a reevaluation with cardiac MRI. Additionally, the investigators will aim at recruiting additionally 400 patients with type 2 diabetes. The aim it to characterize the phenotype of diabetic cardiomyopathy. Uniquely using cardiac MRI we can measure myocardial microvascular function, myocardial localised and diffuse fibrosis in addition to the quantification of myocardial structure and systolic and diastolic function.

Various factors affect the performance of the heart: The contractile properties of myocardial muscle cells are the fundamental devices for translating tension-generation and shortening of the cardiac muscle into pressure-generation and blood volume ejection from the heart into the body. On the other hand, the performance of heart can be analyzed with respect to input and output of blood to/from the hollow cardiac muscle and evaluated in terms of the performance of a pump: With every heartbeat blood is sucked from a low-pressure system (veins) and pumped to the arterial high-pressure system via one-way valves, whereas efficiency, ejected blood volume, blood flow and pressures are linked by hemodynamic laws. Cardiac magnetic resonance (CMR) is the "gold standard technique" to determine cardiac function and muscle mass, as well as for non-invasive diagnosis of myocardial necrosis/fibrosis. Furthermore, new CMR imaging techniques enabling the measurement of myocardial magnetic relaxation times for characterization of myocardial morphology and the acquisition of time-resolved, three-dimensional blood flow velocity fields in the heart and surrounding vessels, represent promising tools for the evaluation of the interaction between myocardial morphology and cardiac function. Aim of this explorative study is to 1. identify myocardial pathology-associated blood flow patterns in the heart and surrounding great vessels, and 2. correlate characteristic blood flow patterns in the heat (existence of vortices, vorticity, vortex formation, propagation dynamics …) with myocardial injuries.

The Hearts in Rhythm Organization (HiRO) is a national network of Canadian researchers/clinicians, working towards a better understanding of the rare genetic causes of sudden cardiac death (SCD). Canadian adult and pediatric electrophysiology centres across Canada work together to gather data and bio sample in a national data registry and bio bank hoping to improve the detection and treatment of inherited heart rhythm disorders to prevent sudden death.

After cardiac surgery, there is a high prevalence of postoperative atrial fibrillation (POAF). However, its diagnostic and therapeutic management is poorly codified. This pathology is caused by atrial abnormalities which form the concept of atrial cardiomyopathy. New tools affording to itemize the atrial cardiomyopathy are needed. Indeed, current tools, as echocardiography and electrocardiogram are relevant but only lead to a raw evaluation of the atrial cardiomyopathy. MRI, because of the assessment of the atrial fibrosis by late gadolinium assessment (LGE) and 4D flow magnetic resonance imaging (MRI) could be relevant to specify the atrial cardiomyopathy.

This is a prospective multi-center international registry. The objective of this registry is to collect prospective data on patients undergoing catheter ablation for Ventricular Tachycardia (VT) and Premature Ventricular Contractions (PVC). The registry will be used for clinical monitoring, research, and quality improvement purposes.

This is a multicentre European double-blind,randomized and controlled trial with 2 parallel groups (1 study medication, 1 placebo) in order to analyse the impact of ACE inhibitors (ACEi) in subjects who carry a mutation but have not yet developed DCM (dilated cardiomyopathy). Objective of the trial: Study the impact of ACE inhibitors (ACEi) in subjects who carry a mutation (leading to a genetic form of heart failure) but have not yet developed DCM. Context. Dilated Cardiomyopathy (DCM) is one of the leading causes of Heart Failure due to systolic dysfunction and at least 30% of DCM are of familial/genetic origin, usually with autosomal dominant inheritance, and underlying genes and mutations are increasingly identified. Familial Dilated Cardiomyopathy (fDCM) is characterized by age-related penetrance (or delayed-onset), that means that the cardiac expression of the disease (echocardiographic abnormalities) is usually absent for a long period and progressively appears with advanced age, usually after 20 years of age Hypothesis : ACEi may delay or prevent the occurrence of DCM in these subjects (pre-clinical stage). Expected results: If the hypothesis is confirmed, and as a consequence, the knowledge derived from basic research (genes identification in DCM) will be translated into clinical practice (early identification of subjects at high risk of developing heart failure through predictive genetic testing) with the development of new therapeutic management (early ACEi) that will help to decrease the morbidity and mortality associated with the disease. This will constitute a paradigm of the development of preventive medicine thanks to the development of genetics in the cardiovascular field. Subjects who are concerned are ≥18 years of age and ≤60 years, carry a mutation responsible for DCM and are at a preclinical stage of the disease. Total duration of treatment (perindopril versus placebo) is 3 years. A total number of 200 participants will be enrolled (100 in each group) in 7 centres.

The purpose of this study is to evaluate whether patients with chronic heart failure not due to coronary artery disease who require use of a left ventricular assist device (LVAD) for refractory heart failure can recover sufficient heart function to allow the pump to be explanted. The study aims to avoid the need for transplantation in these patients by using standard heart failure medications to reduce the size of the left ventricle and then using the investigational drug, clenbuterol, to further improve left ventricular function.

CMR GUIDE DCM is a randomized controlled trial with a registry for non-randomized patients. Patients enrolled will have non-ischemic cardiomyopathy (NICM) with mild to severe Left Ventricular (LV) systolic dysfunction with replacement fibrosis identified on Cardiac Magnetic Resonance (CMR). 954 patients will be randomised from 50 sites across 4-6 countries worldwide to receive an implantable defibrillator (ICD) or implantable loop recorder (ILR). Device and clinical follow-up will be performed at 3, 6, 12, 24, 36 months and at end of study.

Fluoroscopy guided EMB and EAM guided EMB on all patients meeting existing guidelines for biopsy.
