Filter by:The goal of this study is to evaluate left atrial structural and functional abnormalities in stroke of undetected mechanism and atherosclerotic stroke with cardiac MRI.
The aim of this study is to compare the effects of Ivabradine and metoprolol to reduce heart rate prior to coronary CT angiography in patients with advanced heart failure.
Overall Research Strategy of this protocol is to refine and validate noninvasive CMR imaging sequences with invasive hemodynamic and pathology results to create a comprehensive, noninvasive, radiation-reduced regimen for pediatric cardiomyopathy and cardiac transplant assessment. We were the first to perform MR-guided cardiac catheterization in US children, and have accumulated the largest US experience, having performed over 75 procedures to date. Our unique experience puts us in strong position to leverage this technology to improve care of children with cardiomyopathy and transplant. Using an integrated approach, we will simultaneously (1) validate imaging measures of cardiac edema and fibrosis by correlating T1 and T2 map images with endomyocardial biopsy (EMB) results in Aim 1; (2) overlay T1, T2 map images into our x-ray system to display "hotspots" of T1 and T2 abnormalities to guide EMB in Aim 2; and (3) obtain radiation-free hemodynamic data in a highly vulnerable pediatric population by using CMR to guide catheter manipulation in the ICMR suite in Aim 3. Age and diagnosis-matched historical controls will be identified from the last 10 years at Children's National as a control population for specific purposes of comparing (1) EMB yield without image overlay and (2) Radiation exposure during X-ray guided right heart catheterization. Identical information will be obtained and stored in the same 45CFR compliant database. Historical controls will be identified from the cardiac catheterization database by searching for age and diagnosis. A waiver of consent will be applicable here, as it would be inconvenient, insensitive and not feasible to consent families who have already undergone treatment.
In this study, the investigators will recruit a cohort of elderly Black and Hispanic patients with heart failure to define the number of patients who have cardiac amyloidosis by utilizing highly sensitive heart imaging and blood tests. The investigators will also explore differences in genetics and sex as they relate to heart failure disease progression in cardiac amyloidosis.
Myocarditis promotes the occurrence of serious cardiac arrhythmias and conduction disorders which may lead to sudden cardiac death, the need for catheter ablation of arrhythmia or implantation of a cardioverter-defibrillator or pacemaker. The aim of the study is to fill the evidence gap regarding the type and burden of arrhythmias in patients with myocarditis and their correlation with clinical parameters, biomarkers and additional tests. During a multi-center observational study, patients will be subjected to prolonged ECG monitoring. As a result, a risk scale will be created that can facilitate the identification of patients with an increased risk of arrhythmia and further specifying recommendations for therapeutic management.
The study will investigate whether a new high resolution heart Magnetic Resonance Imaging scan, combining assessment of ischemia and viability by perfusion and Late Gadolinium Enhancement -Cardiac Magnetic Resonance is superior to Late Gadolinium Enhacement imaging alone in predicting functional recovery following revascularisation.
The overall aim of the project is to test the feasibility and safety of allogeneic adipose-derived stromal cells (CSCC_ASC) investigational medicinal product, to improve myocardial function in patients with non-ischemic dilated cardiomyopathies (NIDCM) and heart failure.
Left ventricular dysfunction is common in the critically ill. The aim of this study is to assess the incidence and prognosis of left ventricular dysfunction in critically ill patients.
The prognostic relevance of isolated non-ischemic LGE (i.e. with no underlying "labelled" cardiomyopathy) is unclear, and current guidelines to not state on the clearance of athlete with this type of findings as regards to competitive or intense sport practice. The principal objective of the study is to evaluate during a five-years follow up, the clinical outcome of athletes with this kind of findings. The secondary objective is the determination of prognostic factors. The management and follow-up of the athletes will be let at the appraisal of each center.
This study aimed to use cardiac magnetic resonance imaging (CMR) to evaluate the efficacy and safety of bisoprolol therapy for boys with Duchenne muscular dystrophy(DMD) and preserved ejection fraction. On top of angiotensin-converting enzyme inhibitor (ACEI) , half of the participants will receive bisoprolol in combination, while the other half will not receive any beta-blocker.
