The Low Voltage Guided Ablation Trial of Persistent Atrial Fibrillation
Persistent Atrial FibrillationThis study evaluates if the exclusion of left atrial low voltage areas / scars by ablation lines in addition to pulmonary vein isolation may improve the outcome in patients with persistent atrial fibrillation in comparison to stand alone pulmonary vein isolation.
Determining the True Incidence of Atrial Fibrillation Before and After Lung Resection
Lung CancerAtrial Fibrillation1 moreLung resections for pulmonary malignancies offer the best chance of survival for patients, but these procedures carry a significant burden of post-operative morbidity and mortality. Patients are particularly at high risk for post-operative atrial fibrillation (a condition involving irregular heart rhythm). Atrial fibrillation with symptoms can increase the risk of stroke - a blockage in a major blood vessel in the brain, which can potentially result in a disability or even death. The objective of this study is to establish the feasibility of using ambulatory heart rate monitoring to determine the total incidence of atrial fibrillation in the peri-operative period before and after anatomic lung resection for malignancies. The study will also investigate the correlation between atrial fibrillation and rates of stroke and other adverse events, as well as serve to identify the patients that are at a higher risk of developing atrial fibrillation.
Apixaban Evaluation of Interrupted Or Uninterrupted Anticoagulation for Ablation of Atrial Fibrillation...
Atrial FibrillationThe purpose of the prospective, randomized cohort in this study is to assess the safety and efficacy of 2 apixaban treatment strategies (uninterrupted versus interrupted) in subjects planned to undergo catheter ablation for the treatment of non-valvular atrial fibrillation (NVAF). Simultaneously, a retrospective cohort of 300 warfarin-treated individuals, identified by chart review, who are matched to the prospective randomized subjects, will be identified. The purpose of the retrospective warfarin cohort is to compare the efficacy and safety of warfarin(the current clinical practice) to that of apixaban (uninterrupted, interrupted, combined uninterrupted and interrupted).
Edoxaban Compared to Standard Care After Heart Valve Replacement Using a Catheter in Patients With...
Atrial FibrillationWhen the upper chambers of a person's heart receive or generate irregular electrical signals, it causes abnormal rhythm in the heartbeat. This is called atrial fibrillation. Atrial fibrillation goes along with blood clots that may cause mainly strokes and less often other diseases, such as a heart attack. Some patients with atrial fibrillation have other heart disease, such as heart valves that may need to be replaced using catheters. Often doctors give patients drugs that reduce those blood clots. These are either vitamin K antagonist (VKA) or direct anticoagulants, such as edoxaban. In these patients, it is unclear which of the drugs is better for reducing stroke without increasing severe bleedings.
Compare Apixaban and Vitamin-K Antagonists in Patients With Atrial Fibrillation (AF) and End-Stage...
Atrial FibrillationEnd-stage Kidney DiseaseThe Study is an open-labeled, randomized controlled trial, phase IIIb. Its objective is to assess the safety of the factor Xa inhibitor apixaban versus the vitamin-K antagonist (VKA) phenprocoumon in patients with NVAF and ESKD on hemodialysis. The safety will be assessed by means of the incidence of major and clinically relevant, non-major bleeding on anticoagulation.

Dabigatran Versus Conventional Treatment for Prevention of Silent Cerebral Infarct in Atrial Fibrillation...
Atrial FibrillationValve Heart DiseaseThe prevalence of AF, which is tachyarrhythmia, is approximately 2% of the entire population and 5% of the population at the age of 60 or older. AF is the cause of approximately 20% of all events of ischemic stroke, and patients with AF are known to be at 6 to 10% risk of ischemic stroke per year. Patients with valvular AF are known to have a higher incidence of stroke than patients with nonvalvular AF. However, the relevant data are insufficient as large randomized studies comparing NOAC treatment with warfarin, a conventional treatment, did not include many patients with moderate and severe valvular AF. Ischemic stroke is divided into symptomatic stroke with brain lesions on brain magnetic resonance imaging (MRI) and silent cerebral infarct with lesions on brain MRI but without stroke symptoms. According to a brain MRI follow-up study, the incidence of silent cerebral infarct was 17.7% (254 subjects) over a period of 5 years, with 11.4% of 254 subjects reporting to have experienced symptoms. This means that the incidence of silent cerebral infarct is approximately 9 times that of symptomatic stroke. In addition, patients with a history of silent cerebral infarct are known to be approximately twice more likely to experience stroke in the future than those without a history of silent. Brain microbleed is easily detected by brain MRI and is a well-known independent predictor of intraparenchymal hemorrhage and silent cerebral infarct. The prevention of stroke by the study drug can be indirectly assessed based on the incidence of silent cerebral infarct and brain microbleed on brain MRI. Investigators tried to compare effect of dabigatran with conventional treatment in terms of prevention of stroke by comparing incidences of silent cerebral infarct and brain microbleed and symptomatic stroke using brain MRI.
