To investigate the effect of VTA ablation at the time of LVAD implant to see if it can reduce the incidence of VTA after surgery
Midwall septal fibrosis (MSF) is a common structural abnormality in non-ischaemic dilated cardiomyopathy (DCM). Its presence is believed to increase the risk of malignant ventricular arrhythmias (VA), but the mechanism of arrhythmogenicity is not known. This is particularly relevant in DCM patients with MSF and mid-range left ventricular ejection fraction (LVEF) as they do not currently fulfil criteria for a primary prevention implantable cardioverter-defibrillator (ICD) insertion. Access to the epicardium for electrical measurements of the heart can enhance the understanding of arrhythmogenicity in DCM, however direct epicardial access is invasive. Instead, the investigators will non-invasively combine high resolution 256-lead ECG imaging (ECGI) and latest generation cardiovascular magnetic resonance (CMR) to study the hearts of 60 DCM patients with and without MSF regardless of LVEF, and 60 matched healthy volunteers. The investigators recently invented the re-usable and CMR-safe SMART-ECGI vest technology for this purpose. Using supercomputers, the investigators will fuse the collected ECGI/CMR data and run electromechanical simulations of whole-heart activation to non-invasively measure each participant's personalised risk of malignant VA induction. By panoramically mapping the DCM heart in a single beat, the investigators aim to elucidate how MSF perturbs the cardiac activation front and how this could lead to life-threatening VA. This has the potential to change the method by which cardiologists risk stratify patients with DCM.
Prospective, nonrandomized, single-center, comparative study to define if right ventricular (RV) contractile reserve assessed by exercise CMR helps to improve the differential diagnosis between pathological and physiological remodeling of the RV; ie. arrhythmogenic right ventricular cardiomyopathy (ARVC) and athlete's heart.
Dilated cardiomyopathy (DCM) is an increasingly recognized cause of morbidity and mortality with heterogenous etiologies (eg, genetic, environment) and clinical manifestations, characterized by left ventricular (LV) systolic dysfunction and LV or biventricular dilation. Previous publications reported the three-year treated mortality rates remain high at 12%-20% and a reported 5-year mortality rate up to 50%, with death resulting from ventricular arrhythmia leading to sudden cardiac death (SCD) or advanced heart failure (HF). With large fields of view and high spatial resolution, Cardiac magnetic resonance (CMR) is the reference standard for assessing cardiac mass, volume, and function. CMR also provides non noninvasive characterization of the myocardium benefiting to differential diagnosis and risk stratification.
Heart failure is the primary cause of morbidity and mortality worldwide. Currently drug treatments for heart failure manage the symptoms, but not restore the loss cardiomyocytes due to the very limited regenerative capability in the adult heart. Novel reparative therapies that replace the cardiomyocytes loss are highly demanded to restore the cardiac function. The main purposes of this explanatory study is to investigate the safety and efficacy of the catheter-based endocardial delivery of human iPSC-derived cardiomyocytes in patients with congestive heart failure.
The multicenter Cardiology Monitoring Platform registry (mCMP-registry) is a prospective observational registry including multi-omics (diagnostic) measurements performed as part of routine clinical care, bio-banking (optional), and yearly questionnaires (optional). It's objective is to optimize (early) diagnosis and risk-stratification of (early) cardiovascular diseases, specifically cardiomyopathy phenotypes, arrhythmias, and coronary artery disease, and to create a better understanding of underlying pathophysiological processes.
In this study, patients with ATTR-CM or gene carriers were selected to study the diagnosis and treatment, and long-term follow-up was conducted.
this is an observertional study aimed at Study the association between the level of irisin expression and (Fibronectin Type III Domain Containing 5 (FDNC5) gene polymorphism in female patients with peripartum cardiomyopathy.
In this study, patients diagnosed with Al-CM were selected to observe the effect of treatment and conduct long-term follow-up.
