Filter by:Catheter ablation is an established standard therapy in interventional treatment of atrial fibrillation.The trial investigates the influence of genetic risk for the recurrence of atrial fibrillation after catheter ablation.
The aim of this study is to evaluate safety and clinical outcomes after different pacing approaches of conduction system pacing in a prospective registry.
Post-operative atrial fibrillation is a common problem post cardiac surgery with rates exceeding 30%. Atrial fibrillation has multiple adverse effects on cardiac hemodynamics and can lead to hypotension, diminished end organ perfusion and lengthen the stay in ICU. Amiodarone is the medication of choice used for pharmacological cardioversion and can be used with vasoactive medications. Intravenous amiodarone is associated with hypotension and end organ perfusion requiring escalation in vasoactive support. Vernakalant is novel anti-arrhythmic agent approved in Canada for cardioversion of atrial fibrillation that primarily works on atrial channels and has no effect on contractility or vasodilation. Clinical trials have proved good efficacy of Vernakalant in conversion of paroxysmal atrial fibrillation however there is no comparison of Amiodarone to Vernakalant in post-operative cardiac surgery. We plan to perform a clinical trial comparing Vernakalant to amiodarone in post-cardiac surgery patients with a primary outcome of cardioversion at 90 minutes. Secondary outcomes will follow duration of vasoactive medications, days in ICU and economics.
The safety of edoxaban treatment will be examined using real-world clinical evidence from adult patients with non-valvular atrial fibrillation (NVAF) indications in routine clinical practice.
The objective of this study is to evaluate whether local impedance (DIRECTSENSE™) drop on the INTELLANAV STABLEPOINT™ ablation catheter is associated with late pulmonary vein (PV) reconnections and durable conduction block in patients undergoing de novo PV isolation (PVI) for treatment of paroxysmal atrial fibrillation (PAF).
Patent foramen ovale (PFO) is a prevalent cause of ischemic stroke and transient ischemic attack (TIA) in young patients. Its role as a cause of cerebrovascular events in the older population is more controversial because of other competing causes are more frequent in the elderly. Recent randomized controlled trials (RCTs) have shown that PFO closure is associated with a 59% relative risk reduction in the risk of recurrent ischemic stroke. As such, the number of PFO closure procedures are expected to increase substantially in the upcoming years. Real world data (RWD) informing on the medical management, the risk of stroke recurrence, incident atrial fibrillation, and other outcomes in stroke patients with PFO, with and without PFO closure, will become crucial for understanding how results from RCTs are translated into clinical practice globally. The IMPROVE (International Multicenter Patent foRamen OVale & strokE) Registry is an observational, multicenter, international registry of men and women with an ischemic stroke or TIA. The aim is to enroll 8,800 patient-years at ≥50 sites in ≥20 countries. The IMPROVE Registry will provide important information about the management and related outcomes of patients with ischemic stroke or TIA and PFO throughout different regions of the world and across a wide spectrum of healthcare systems.
The LUX-Dx PERFORM Study will characterize, in a general patient population, the utilization of the remote programming feature of the Boston Scientific (BSC) Insertable Cardiac Monitor (ICM) device. The study will also collect data to characterize the performance of arrhythmia detection algorithms. Finally, data collected will be used to analyze and characterize the ICM system-related safety events.
Although the clinical impact of residual left atrial appendage (LAA) leaks still requires confirmation, its patency resulting from incomplete LAA closure may promote blood stagnation and thrombus formation, and increase the risk of thromboembolic events. The main purpose of this trial is to evaluate the safety and efficacy of percutaneous leak closure with radiofrequency energy applications.
Implantable Loop Recorders (ILR) are small devices the size of a memory stick, which are implanted to investigate stroke, palpitations and fainting episodes. They monitor the heart constantly and detect abnormalities such as slow or fast heart beats and an irregular heartbeat called Atrial Fibrillation (AF). Stroke is a life threatening condition and no cause is identified for over 30% of strokes. AF is a predominant risk factor for stroke. About 30% of patients with stroke are found to have AF when they are monitored with an ILR. Unfortunately not every patient with a stroke can have an ILR; one of the prohibiting factors is cost. Therefore, there is an urgent unmet clinical need to rationalise the use of ILRs and prioritise their implantation in those patients that have most to gain and therefore achieving cost-effectiveness and improving patient care. In order to achieve the above, identifying parameters that can predict the presence of underlying AF is very important. Studies have shown that special factors including patient's other medical problems, family history, factors on paper recording of the electrical activity of the heart, heart monitors and ultrasound scan of the heart can be useful in predicting AF. Also certain blood molecules have been investigated as potential predictors of AF. The aim of this study is to look at all the above factors and combine them in order to determine whether these factors can predict the presence of AF. Identify predictors of AF will allow doctors to identify patients at different risk of having AF and use the ILR in all possible patients that might need it.
Atrial fibrillation is a heart condition that causes an abnormal and fast heart rate. For people with non-valvular atrial fibrillation (NVAF), this is caused by problems such as high blood pressure and diabetes. NVAF happens more often in elderly people and can lead to stroke, heart failure, and death. Doctors are currently able to give patients a type of treatment called an anticoagulant. Anticoagulants work by making the blood thinner. They are thought to help reduce the risk of stroke and death caused by NVAF. In this study, researchers wanted to learn more about what elderly people think of taking anticoagulants that do not have any vitamin K in them. These are called non-VKA oral anticoagulants (NOACs). This study will include up to about 150 Belgian men and women aged 75 years and over who have NVAF and have been treated with NOACs. The study will also include about 10 doctors who have treated these patients. In this study, there will be no required tests or visits. Instead, patients will answer a paper questionnaire about their use of NOACs. The researchers will ask the doctors questions about how they treat their patients using NOACs. The main types of questions the researchers will focus on are: - The patient characteristics of the elderly with NVAF who are treated with NOACs - The level of fear of the elderly about bleeding while using a blood thinner and the fear of stroke/thrombosis. - The geriatrician's thoughts about using NOACs to treat NVAF in elderly patients - Those patient characteristics geriatrician's find most important when deciding on the anticoagulation treatment in the elderly patients. The information from this study will be collected between February and April 2021. But, the whole study will take about 6 months to finish and is expected to end in July 2021.
