Filter by:The Dilated Cardiomyopathy-Cardiac Magnetic Resonance (DCM-CMR) Study is an ancillary study from the parent study, DCM Precision Medicine Study. The rationale for the DCM-CMR study is to leverage cardiac magnetic resonance (CMR) imaging to detect earliest findings of DCM in the at-risk family members enrolled into the parent study.
The purpose of this observational study is to evaluate the performance of the Berlin Heart EXCOR Active driving unit while being used with the approved EXCOR ventricular assist device system.
Manganese is a calcium analogue which actively enters viable cells with intact calcium-handling mechanisms and its uptake is evident by an increase in MRI-detectable T1 relaxivity of tissues. Mangafodipir is a novel manganese-based magnetic resonance imaging (MRI) contrast medium with unique biophysical properties that are ideal for application to cardiac imaging. Recent studies in man have demonstrated the utility of manganese-enhanced MRI (MEMRI) in assessing infarct size more accurately than with standard cardiac MRI protocols using gadolinium enhancement and have shown reduced myocardial manganese uptake in patients with cardiomyopathies suggesting abnormal calcium handling. Understanding the potential for myocardial recovery is key in guiding revascularisation therapies in ischaemic cardiomyopathy, in addition to novel therapies used in heart failure. Being able to monitor calcium handling and therefore myocardial function in different types of cardiomyopathies has the potential to guide management in these patients. The investigators here propose an investigational observational study of MEMRI to assess myocardial calcium handling in reversible causes of cardiomyopathy, namely ischaemic cardiomyopathy, myocarditis and takotsubo cardiomyopathy.
- To determine normal T1 and T2 values of the liver, and to assess the impact of age and gender - To determine the relation between markers of right heart decompensation and T1/T2 values of the liver in patients with pulmonary hypertension, patients with dilated cardiomyopathy, and patients with constrictive pericarditis (or constrictive physiology) - To determine inter/intra-observer reproducibility for liver T1/T2 assessment - To test/develop multi-feature texture analysis for T1/T2 analysis of the liver and implement machine learning to derive indicative features (MR-derived measures only vs combined with other clinical readouts)
This prospective study is designed to evaluate the efficacy, safety, and tolerability of ALXN2060 (also known as AG10), as well as to establish its pharmacokinetic and pharmacodynamic profile in Japanese participants with symptomatic ATTR-CM administered on a background of stable heart failure therapy.
This is an online registry and database of patients with cardiomyopathy and myocarditis, coupled with an observational study of DCM and HCM.
Sudden cardiac death (SCD) risk stratification is a challenge in non-ischemic cardiomyopathy (NICM). The underlying mechanism of monomorphic ventricular tachycardia (VT) is mostly scar related. While electrophysiological mechanisms underlying ventricular arrhythmia are well known, late gadolinium enhanced (LGE) cardiac MRI-3D reconstructions are now able to guide VT ablation procedures. Such exam may help in identifying specific properties of scar at risk of malignant arrhythmia.
Background: HCM is a genetic heart disease. It can cause fatigue, chest pain, or even death. For more than 50 years, a surgery called septal myectomy has been used to help people with this disease. Dr. Andrew G. Morrow originated the surgery and performed it more than 200 times at NIH starting in 1960. Researchers want to learn the long-term success of this surgery. Objective: To determine long-term survival at least 35 years after surgical myectomy at NIH and examine data for people who are confirmed to be deceased or alive. Eligibility: People who had surgical myectomy by Dr. Morrow from 1960 to 1983. Design: This study uses images and data that were obtained in the past. Many of the participants are deceased. Most of the others are no longer being followed at the NIH. The medical records of people treated by Dr. Morrow were microfiched. These records can be accessed at the NIH. The records will be searched for keywords to find participants for this study. Participants clinical data, such as lab testing and imaging, will be used. Other data collected as part of the original study will also be used. Researchers will use participants name, date of birth, and Social Security number to learn if they are alive or deceased. If they are deceased, researchers will try to find the age of death. Online databases and search engines will also be used. Survival data will be compared to data from the general U.S. population for the same time period. Data will be stored in a database that is password protected. The study will last about 1 year.
This study will be conducted to evaluate the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of NTLA-2001 in participants with hereditary transthyretin amyloidosis with polyneuropathy (ATTRv-PN) and participants with hereditary transthyretin amyloidosis with cardiomyopathy (ATTRv-CM) or wild type cardiomyopathy (ATTRwt-CM)
Rationale: Permanent cardiac pacing is the only available therapy in patients with atrioventricular (AV) conduction disorders and can be life-saving. Right ventricular pacing (RVP), the routine clinical practice for decades in these patients, is non-physiologic, leads to dyssynchronous electrical and mechanical activation of the ventricles, and may cause pacing-induced cardiomyopathy and heart failure. Left ventricular septal pacing (LVSP) is an emerging form of physiologic pacing that can possibly overcome the adverse effects of RVP. Study design and hypotheses: The LEAP trial is a multi-center investigator-initiated, prospective, randomized controlled, open label, blinded endpoint evaluation (PROBE) study that compares LVSP with conventional RVP. A total of four hundred seventy patients with a class I or IIa indication for pacemaker implantation due to AV conduction disorders and an expected ventricular pacing percentage >20% will be randomized 1:1 to LVSP or RVP. The primary endpoint is a composite endpoint of all-cause mortality, hospitalization for heart failure and a more than 10% decrease in left ventricular ejection fraction (LVEF) in absolute terms leading to a LVEF below 50% at one year follow-up. LVSP is anticipated to result in improved outcomes. Secondary objectives are to evaluate whether LVSP is cost-effective and associated with an improved quality of life (QOL) as compared to RVP. Quality of life is expected to improve with LVSP and reduced healthcare resource utilizations are expected to ensure lower costs in the LVSP group during follow-up, despite initial higher costs of the implantation. Study design: Multi-center investigator-initiated, prospective, randomized controlled, open label, blinded endpoint evaluation (PROBE) study. Study population: Adult patients with a bradycardia-pacing indication because of AV conduction disorders with an expected ventricular pacing percentage of ≥ 20% and a left ventricular ejection fraction (LVEF) >/= 40%. Four hundred seventy patients will be randomized 1:1 to LVSP or RVP. Intervention: LVSP vs RVP. Main study parameters/endpoints: The primary endpoint is a composite of all-cause mortality, hospitalization for heart failure, and a more than 10% point decrease in left ventricular ejection fraction (LVEF) leading to an LVEF below 50%, which as a binary combined endpoint will be determined at one year follow-up. Secondary endpoints are: - Time to first occurrence of all cause mortality or hospitalization for heart failure. - Time to first occurrence of all cause mortality. - Time to first occurrence of hospitalization for heart failure. - Time to first occurrence of atrial fibrillation (AF) de novo. - The echocardiographic changes in LVEF at one year. - The echocardiographic changes in diastolic (dys-)function at one year. - The occurrence of pacemaker related complications. - Quality of life (QOL), cost-effectiveness analyses (CEA) and budget impact analysis (BIA). The secondary endpoints (other than echocardiographic LVEF change) will be determined at the end of the follow-up period, when the last included patient has reached one year follow-up. The individual follow-up time for patients at this time point will vary with a minimum of one year.
