Filter by:The patients who undergo ICD(implantable cardioverter defibrillator) implantation for the primary prevention of sudden cardiac death with severe LV(left ventricle) dysfunction (ejection fraction ≤ 40%) by ICM(idiopathic cardiomyopathy). Indications for ICD implantation for primary prevention in accordance with 2016 revised Korean indication guideline on ICD implantation - FU LVEF(Left Ventricular Ejection Fraction) ≤ 30% (at least 40 days post-myocardial infarction) - FU LVEF 31~35%, NYHA(the New York Heart Association) class II, III (at least 40 days post-myocardial infarction) - FU LVEF ≤ 40%, NSVT(non-sustained ventricular tachycardia) (Holter), inducible VF(ventricular flutter) or sustained VT(ventricular tachycardia) at electrophysiological study (at least 40 days post-myocardial infarction)
The prevalence of valvular heart disease is on the rise along with the aging society and the generalization of echocardiography. Furthermore, the rheumatic valvular heart disease is much more prevalent in Asia than in Western countries, and the frequency of valve disease is higher in Asia. The effect of an implantable cardioverter defibrillator (ICD) in the primary prevention of sudden cardiac death in ischemic cardiomyopathy is well established and has become a standard of care. However, there is limited research on the effect of ICD implantation for primary prevention in patients with heart failure due to valvular heart disease. In a small study, the incidence of fatal cardiac arrhythmia was lower in patients with valvular cardiomyopathy (5%) who received ICD implantation for primary prevention than in those with ischemic cardiomyopathy. But there is also a report that the appropriate ICD treatment is not different from that of ischemic heart disease in valvular heart disease patients. Therefore, it is necessary to study the primary prevention effect of ICD on valvular cardiomyopathy in a larger number of patients. The purpose of this study was to investigate the effect of ICD on the prevention of sudden cardiac death in patients with heart failure due to valvular heart disease through prospective, multicenter, and observational studies.
DCM Support is recruiting patients with dilated cardiomyopathy and heart failure symptoms. The goal of this clinical trial is to examine whether treatment with a patient's own stem cells can improve their heart function and alleviate heart failure symptoms. - Stem cells will be collected from bone marrow in the patient's hip under local anaesthetic. - The stem cells will be infused into the arteries that supply blood to the heart under local anaesthetic. - A mini heart pump will be used to take the strain off the heart during the procedure. - The follow-up involves a phone call at 1 month and clinic visits at 3 and 12 months
RIKADA is a prospective study performing systematic family screening including clinical and genetic testing in pediatric patients with primary cardiomyopathy and their first-degree relatives with the aim to facilitate risk stratification.
The aim of the study is to find better and more specific non-invasive methods to diagnose and stage cardiac sarcoidosis with the use of advanced imaging modalities, simultaneous 3T MRI and PET. Cardiac sarcoidosis is a disease of possibly fatal outcome in young people. The use of a combined PET/MRI system with 18F-FDG and a new inflammation-tracer (18F-GE180) can become a future game changer. Sarcoid induced focal inflammation in myocardium should show high 18F-GE180 uptake. 18F-GE180 PET scans will give reliable data about inflammatory sarcoidosis activity in the myocardium. 18F-GE180 PET is expected to improve diagnostic accuracy compared to 18F-FDG-PET and/or contrast enhanced MRI.
This is a non-randomized, prospective, multi-center Early Feasibility Study of the AccuCinch® Ventricular Restoration System in Patients with Prior Mitral Valve Intervention (PMVI) and Recurrent Mitral Regurgitation.
Hypertrophic cardiomyopathy (HCM) is very common. The thickened heart muscle can disrupt the normal functioning of the heart's electrical system, resulting in fast or irregular heartbeats. Today, there are no reliable means to identify HCM patients at risk of sudden death. The CardioInsight™ has recently been developed by Medtronic for non-invasive advanced cardiac mapping system. The CardioInsight™ Noninvasive 3D Mapping System is a non-invasive mapping system that collects chest ECG signals and combines these signals with CT scan data to produce and display simultaneous, bi-atrial and biventricular, 3-D cardiac maps. It is a monocentric, prospective, comparative and analytical study. 20 HCM patients will be recruited in the National Reference Center for inherited cardiac diseases of Lyon. The 3D-propagation maps of 10 well phenotyped and genotyped HCM patients with previous VF (ventricular fibrillation) will be compared to 10 HCM patients without previous VF. After consent signed, Holter ECG, scanner and CardioInsightTM 3D_ECG mapping will be planned in the month following the inclusion. 12-lead ECG, 24h holter ECG, cardiac scanner will be performed as standard procedure of each center in the current health care of the patient. The widespread screening of HCM patients with 3D high-density noninvasive mapping should improve the risk-benefit ratio of implantable defibrillator therapy. It is expected that more patients at risk will benefit from this device.
Patients with ischemic cardiomyopathy (left ventricular ejection fraction <35%) and heart failure who already have an implantable device with an atrial lead (dual chamber defibrillator or biventricular defibrillator) will undergo sequentially 1. Sham low level tragus stimulation (LLTS) (5min), 2. Active LLTS at 5Hz (15min) and 20Hz (15min) and 3. Active LLTS group with atrial pacing at 100bpm at 5Hz (15min) and 20Hz (15min). The latter is required to examine the effect of LLTS on RA independent of heart rate. Repolarization alternans will be measured by analyzing a regular 12-lead ECG using a custom-made software.
Aims and objectives: The primary objective of this study is to assess whether a structured exercise program improves cardiac relaxing properties in patients with hypertrophic cardiomyopathy (HCM). Background: HCM is a hereditary disease in which the myocardium becomes thickened without an identifiable cause (other than genetic). It is the most common genetic cardiovascular disease with an estimated prevalence of 1/500 (i.e. 10.000 affected individuals in Denmark). The majority of patients with HCM suffers from shortness of breath and reduced exercise capacity due to increased left ventricular (LV) stiffness. Exercise training has been shown to improve exercise capacity and symptoms in patients with HCM, but the mechanisms responsible for this improvement are not known. Methods and materials: The study is a randomized, single blinded, prospective, controlled clinical trial. Eighty patients are recruited from outpatient clinics in the Capital Region of Denmark. Patients are randomized in a 1:1 ratio to 12 week of moderate-intensity exercise training or usual activity level. Assessments will include right heart catheterization, echocardiography, cardiopulmonary exercise testing, blood-samples, quality of life, and, in a subgroup of patients, cardiac magnetic resonance imaging. The primary end-point is change in LV filling pressure assessed as pulmonary capillary wedge pressure at 25 W workload. Expected outcome and perspectives: The investigators hypothesize that an exercise training program will reduce cardiac stiffness and improve symptoms in patients with HCM. Training of HCM patients has long been debated and the topic is poorly researched. The effects of exercise on hemodynamics in HCM patients are unknown and a better understanding of these mechanisms is pivotal for improving treatment.
This prospective, multicenter open-label study will evaluate the long-term safety, tolerability, PK and PD of AG10 administered on a background of stable heart failure therapy.
