Filter by:Ventricular tachycardia (VT) is a life-threatening cardiac rhythm disturbance which leads to sudden cardiac death (SCD), ventricular fibrillation, electrical storm, hemodynamic collapse, and syncope. VT patients with cardiomyopathy (diseased/scarred cardiac muscle) have the highest risk of SCD (<1-4%) and recurrent VTs (15-35%). Although an implantable cardiac defibrillator (ICD) is the most effective treatment option to prevent SCD, it does not eliminate it. Without VT prevention, recurrent VT and ICD shocks may increase the risk of heart failure and death. The primary objective is to determine the optimal treatment strategy to maximize event-free survival among cardiomyopathy patients with ventricular tachycardia (VT) by the creation of a prospective, multicenter, longitudinal cohort. Also, the investigators will evaluate the epidemiology of VT, adherence to guidelines, safety, effectiveness, and cost-effectiveness of current treatment options for secondary prevention of VT in the real-world Canadian VT population.
RADIATE-VT is a pivotal, multicenter, randomized trial comparing safety and efficacy between cardiac radioablation (CRA) using the Varian CRA System and repeat catheter ablation (CA), for patients with high-risk refractory ventricular tachycardia (VT) who have experienced VT recurrence after CA and are candidates for additional CA.
NODE-202 is a Phase 2, multicenter, multinational, single dose, open-label, 2-part, sequential design study in pediatric patients with an established diagnosis of paroxysmal supraventricular tachycardia (PSVT) presenting with a symptomatic episode of PSVT. In Part 1, at least 30 patients aged 12 to <18 years will be enrolled and treated with etripamil nasal spray (NS). Efficacy, safety, tolerability and PK (for at least 12 patients) will be assessed after administration of 70 mg etripamil NS (Part 1A). At least 18 subsequent patients will be enrolled and treated with the etripamil NS with the dose determined by the Pharmacokinetic (PK) analysis and will undergo efficacy and safety/tolerability assessments (Part 1B). In Part 2, at least 30 patients aged 6 to <12 years will be enrolled and treated with etripamil NS at a dose selected based on appropriate body size-based modeling, as well as efficacy, safety/tolerability, and PK data collected in Part 1. Efficacy, safety, tolerability and PK (for at least 12 patients) will be assessed after administration of etripamil NS (Part 2A). At least 18 subsequent patients will be enrolled and treated with the etripamil NS with the dose determined by the PK analysis and will undergo efficacy and safety/tolerability assessments (Part 2B). The study will include the following visits: A Screening Visit, A Treatment Visit, , and A Follow-Up/End of Study Visit.
The goal of this registry database is to demonstrate the safety and effectiveness of functional ventricular tachycardia (VT) ablation using SENSE protocol in patients with ischaemic VT. Mortality and the need for ICD therapies at 12 months post-ablation will be compared with propensity-matched controls undergoing substrate-based ablation alone.
Ventricular tachycardia (VT) is an abnormal rhythm arising from the bottom chambers (ventricles) of the heart. The hearts of most patients who develop VT have been previously damaged by a myocardial infarction (heart attack) or other heart muscle diseases (cardiomyopathies). The damage produces scar or fatty deposits that conduct electrical impulses slowly allowing VT to occur. Recurrent episodes of VT can compromise heart function and increase mortality. VT is prevented by special drugs but these are not always effective and can have many side effects. Most patients with VT will also have a specialised device called an implantable defibrillator (ICD) implanted. The ICD treats VT by either stimulating the heart rapidly or delivering a shock to it. ICDs are very effective but the shocks are painful and have a big impact on quality of life. If VT occurs despite optimal drug treatment, patients undergo an invasive procedure called catheter ablation. Here, wires are passed into the heart from the blood vessels in the leg and the damaged heart muscle causing the VT is identified whilst the heart is in VT. An electrical current is passed down the wire making its tip heat up allowing discrete burns (ablation) to be placed inside the heart. The ablated heart muscle doesn't conduct electricity which stops the VT and prevents it recurring. Some patients are so frail that ablation cannot be performed safely. A recent clinical trial has shown that VT can be treated in such patients using radiotherapy, which is usually used to treat tumours with high energy radiation. This approach is non-invasive, painless and requires no sedation or anaesthesia. This study will test whether VT can be successfully treated using stereotactic ablative radiotherapy. This can deliver high dose radiotherapy very precisely, whilst minimising the risk of damage to healthy tissues.
Newborn screening (NBS) is a global initiative of systematic testing at birth to identify babies with pre-defined severe but treatable conditions. With a simple blood test, rare genetic conditions can be easily detected, and the early start of transformative treatment will help avoid severe disabilities and increase the quality of life. Baby Detect Project is an innovative NBS program using a panel of target sequencing that aims to identify 126 treatable severe early onset genetic diseases at birth caused by 361 genes. The list of diseases has been established in close collaboration with the Paediatricians of the University Hospital in Liege. The investigators use dedicated dried blood spots collected between the first day and 28 days of life of babies, after a consent sign by parents.
Background: Exposure to high altitudes has been associated with an increased risk of cardiac arrhythmias in healthy subjects and an increased risk of sudden cardiac death. Aim: The aim of the present study is to evaluate the risk and the incidence of cardiac arrhythmias at extreme altitude. Methods: This is a prospective cohort study of healthy volunteers determined to climb Mount Everest. Subjects will be evaluated for eligibility by electrocardiography and echocardiography. All study participants will undergo ambulatory rhythm monitoring in their home environment within 12 weeks of the climb. Subsequently, ambulatory rhythm monitoring will be repeated during the ascent from basecamp to the summit of Mount Everest. The primary endpoint will be the composite of supraventricular and ventricular tachyarrhythmias, and bradyarrhythmias.
The objective of this clinical study is to evaluate the safety and effectiveness of the Adagio VT Cryoablation System in the ablation treatment of Sustained Monomorphic Ventricular Tachycardia (SMVT)
Three-arm randomized clinical trial comparing two strategies of TcMS to sham stimulation in patients with VT storm. The hypothesis of the study is that TcMS will reduce the burden of VT in the 24 hours after randomization compared to sham stimulation and that TcMS with theta burst stimulation (TBS) will be more effective at reducing VT burden than low frequency TcMS.
The objective of this study is to demonstrate that higher radiation doses are necessary to induce transmural scar formation which is currently assumed to be the underlying mechanism of successful long-term efficacy of VT treatment and therefore dose-escalation will lead to a significantly reduced long-term VT recurrence rate compared to the currently applied single dose of 25 Gy.
