Filter by:Increasing cases of women with dilated cardiomyopathy with a project of pregnancy are observed. However there is few knowledge and publications about cardiac diseases in pregnant women. Moreover the majority of medical articles deal with women with congenital heart diseases, valvular pathologies or peripartum cardiomyopathies, and few data are available in literature about women with dilated cardiomyopathy diagnosed before or during the first months of the pregnancy. Cardiologist and obstetrician advices are considerably limited when patients with dilated cardiomyopathy have a pregnancy project. Knowledges and know-how are currently based on limited personal experiment or on few clinical cases descriptions. Pregnancy represents a high-risk situation for patients with dilated cardiomyopathy. Creation of a cohort of pregnant women with dilated cardiomyopathy collecting specific data will allow to have a better overview and to appreciate possibilities of a pregnancy project, evolution risks and modalities for medical attention and to improve follow-up and advices delivered to these patients.
When a patient is newly diagnosed of systolic dysfunction without obvious etiology (such as rhythmic, ischemic, or valvular disease), most of the time a coronary angiography is performed. In this situation, the investigators aim to evaluate a strategy with CMR as the front line exam, and invasive coronary angiography performed only in case of ischemic scar on CMR
Study Design: This is an observational study. No treatment or intervention will be assigned to the subjects. All patients will receive full standard of care concomitant medication for the treatment of their cardiac condition. 25 patients with genetically confirmed Anderson-Fabry disease who have a plan to start ERT with Agalsidase Alfa will undergo 2D strain, diastolic stress echocardiography, LV vortex flow analysis, and CMR at baseline and after 1 year of treatment with ERT with Agalsidase Alfa for follow-up.
Background: In children and adults living with HIV, cardiomyopathy is a major source of comorbidity. Traditional echocardiographic measures are insensitive and consequently cardiomyopathy often goes undiagnosed until late stages of disease. Myocardial deformation imaging represents a promising means to identify early dysfunction, but to date there have been no large studies using strain or strain rate to assess cardiac function in children with HIV and to establish predictors of worse cardiac function such as viral burden and ART regimen. These studies are critically important as earlier diagnosis and intervention represent the best means to alter the course of HIV-associated cardiomyopathy. Objectives: To determine the association of biomarker levels, myocardial deformation, and viral load level history in HIV infected children attending Moi Teaching and Referral Hospital (MTRH) clinic. Design: A cross-sectional study on clients attending HIV clinic, MTRH. Setting: Module 4 HIV clinic at MTRH in western Kenya, Africa. Population: HIV-infected children attending clinic in 2017 - 2018 Main Measures: Echocardiographic function assessment, Age, Immune status, other illnesses, ART status. Conclusions: The study will explore the NIH/HIV High Priority Target area of HIV-associated cardiac co-morbidities and will enhance understanding of the relationship between cardiac function and viremia. The investigators expect to be able to reliably define a subset of children with worse cardiac function by risk factors: specific ART regimens, less time virally suppressed, and increased BNP biomarker.
Premature ventricular contractions (PVCs) coexist in patients with heart failure (HF) and LV dysfunction. Frequent PVCs have shown to induce a reversible cardiomyopathy (PVC-CM). This clinical pilot study will enroll 36 patients with frequent PVCs (burden >10%) and CM (LVEF <45%) and randomize them to either: 1) RFA or 2) AADs. Prior to treatment, patients will undergo a baseline cardiac MR if clinically indicated followed by 3-month observation period (optimal HF medical therapy). Changes in LV function/scar, PVC burden/arrhythmias and clinical/functional status (QOL, HF symptoms and admissions, NYHA class) and adverse events will be assessed throughout the observation period and compare with PVC suppression strategies (RFA or AAD). Similar comparison will be made between RFA and AAD treatment groups during a 12-month follow up using a Prospective Randomized Open, Blinded End-point (PROBE) study design. The treatment regimens will be compared in an intention-to-treat analysis. In addition, a total of 20,000 consecutive ambulatory ECG Holter monitors from all participating centers will be screened to identify all patients with probable diagnosis of PVC-CM. This pilot study is intended to estimate the prevalence of this clinical entity and pave the way for a large full scale randomized trial to identify best treatment strategy for patients with PVC-CM. Treating and reversing this underestimated PVC-CM may improve patient's health and subsequently decrease HF healthcare spending.
To assess the safety and effectiveness of the SAPIEN XT transcatheter heart valve in patients with a failing surgical aortic bioprosthetic valve.
PREDICT-DCM Trial is a multi-centre, prospective observational trial including patients with DCM undergoing cardiac magnetic resonance imaging (CMR) prior to ICD or event recorder implantation.
This is a Phase 1/2, multinational, open-label, ascending-dose, delayed-treatment concurrent control clinical study to evaluate the safety and preliminary efficacy of AT342 in subjects with Crigler-Najjar aged ≥1 year. Subjects will receive a single dose of AT342 and will be followed for safety and efficacy for 5 years.
Dilated cardiomyopathy is a heart muscle disorder characterized by systolic dysfunction and dilation of the left or both ventricles.Dilated cardiomyopathy can develop in people of any age or ethnicity, although it is more common in male than female persons occurring at a ratio of about three to one in male to female persons. Dilated cardiomyopathy is the predominant cause of cardiomyopathy in pediatric populations. Annual incidence in pediatric populations has been reported to be much lower than one to one hundred seventy thousand in the United States and one to one hundred forty thousand in Australia. Although pediatric dilated cardiomyopathy has a lower annual incidence than adult dilated cardiomyopathy, the outcome for pediatric dilated cardiomyopathy patients is particularly severe. Dilated cardiomyopathy is the most frequent cause of heart transplantation in pediatric patients. Data from international pediatric dilated cardiomyopathy registries indicate that the rates of death or heart transplantation over one and five year periods were thirty one percent and forty six percent, respectively. Onset of dilated cardiomyopathy is usually insidious but may be acute in as many at twenty five percent of patients. Approximately fifty percent of patients with dilated cardiomyopathy have a history of preceding viral illness.
There is a high correlation between scar areas identified by contrast-enhanced ICE and scar areas identified by conventional electroanatomic mapping. Therefore, the investigators will assess the utility of contrast-enhanced ICE to identify and localize myocardial scar real-time during VT ablation procedures.
