Filter by:Atrial fibrillation (AF) is a leading cause of cardiovascular mortality and morbidity. Asian patients with AF have a higher rate of major bleeding including intracranial hemorrhage (ICH) compared to non-Asians. Non-vitamin K antagonist oral anticoagulants (NOACs) are the safer drugs compared to warfarin due to a lower rate of ICH, but the rate of NOACs use in many Asian AF is much lower than non-Asian countries due to economic concerns. The purpose of the COhort of antithrOmbotic use and cLinical outcomes in patients with Atrial Fibrillation (COOL-AF) Phase 2 registry is to determine the changes in antithrombotic patterns and the impact on clinical outcomes. The COOL-AF Phase 2 study is a prospective observational multicenter study of patients with known or newly diagnosed non-valvular AF in Thailand. The aim is a sample size is 3680 patients from 33 centers within a 2-years enrollment timeline. Patients will be follow-up every 6 months until 3 years. The study outcomes were death, ischemic stroke/systemic embolism, major bleeding, myocardial infarction, heart failure, and quality of life.
PulsedSelect is a prospective, global, multi-center, observational post-approval study. Subjects will be treated with the PulseSelect™ PFA System and followed through 36 months.
This study will assess how two different ablation strategies, using two different ablation catheters during catheter ablation for paroxysmal atrial fibrillation, affect the temperature of the esophagus during ablation, and the risk of injury to the esophagus.
This study is a prospective, multicenter, randomized controlled trial with a non-inferiority design. Participants are patients scheduled for atrial septal puncture. After signing informed consent, subjects will be randomly assigned to either the radiofrequency transseptal puncture system group (referred to as the trial group) or the traditional mechanical transseptal puncture system group (referred to as the control group). All participants will undergo immediate postoperative and discharge clinical follow-ups.
The goal of this clinical trial is to compare two ablation techniques to treat patients with persistent atrial fibrillation (irregular and often very rapid heart rhythm). An ablation is a procedure during which some scars are made on the inside of the heart to break up the electrical signals that cause the irregular heartbeat. In this trial researchers will compare a new technique, which uses tiny electric shocks to make the scars, to the standard technique, which uses heat. The main question the trial aims to answer is: • Does the new technique work as well as the standard technique to prevent the irregular heartbeat from returning within one year of the procedure? Participants will: - Undergo an ablation with either the new or the standard technique - Visit the hospital 1, 3, 6, 9 and 12 months after the procedure for a check-up - Wear a device to register their heart rhythm for 24 hours before the 3 month visit and for 72 hours before the 6, 9 and 12 month visit - Record their heart rhythm at home every week - Complete a questionnaire 3, 6, 9 and 12 months after the procedure
Atrial fibrillation (AF) is a prevalent cardiac arrhythmia affecting millions globally, with projections indicating a doubling of cases by 2050. AF is linked to heightened cardiovascular risks like stroke and increased healthcare costs. Ablation, targeting the arrhythmia substrate, is a method to manage AF, yet recurrence rates remain high (20-45% in the first year). Studies highlight the impact of comorbidities, AF characteristics, ablation techniques, and myocardial remodeling markers on AF progression and ablation efficacy. However, there's no definitive guidance on selecting these factors for predicting treatment success. The aim of this study is to investigate predictors of successful AF ablation in the following areas: (a) clinical factors, (b) electrophysiological, (c) electrocardiographic, (d) ultrasound, (e) cardiac anatomy, (f) biomarkers.
This study hypothesize that injecting calcium chloride (CaCl2) into the major atrial ganglionated plexus (GPs) during on pump Coronary artery bypass graft (CABG) can reduce the incidence of Post operative Atrial fibrillation in the first 7 days after surgery.The study is designed to be prospective interventional study two armed RCT for on pump CABG patient. The intervention arm will be injected with Calcium chloride in the four major atrial ganglionic plexus The control arm will be injected with sodium chloride to determine the effect of Calcium chloride on Post CABG Atrial fibrillation
The goal of this clinical trial is to determine the effect of accelerated pacing (pacemaker lower rate programmed to 80bpm) compared to pacing at the standard programmed lower rate of 60bpm in symptomatic atrial fibrillation patients undergoing pace-and-ablate strategy with LBBAP. The main question it aims to answer is: - To determine the effect of accelerated pacing on health-related quality of life compared to the current standard of care. Secondary questions it aims to answer are: - To study the acute hemodynamic effect of different (accelerated) pacing rates on pulmonary capillary wedge pressure, cardiac output and arterial blood pressure among atrial fibrillation patients undergoing pace-and-ablate strategy. - To study the long-term effects (at 6 months) of accelerated pacing compared to the current standard of care among atrial fibrillation patients undergoing pace-and-ablate strategy on: - NT pro BNP levels - device detected atrial fibrillation burden and daily activity - echocardiographic measurements (LVEF, left ventricular ejection fraction; LVEDD, left ventricular end- diastolic diameter; LVESD, left ventricular end-systolic diameter; LAVI left atrial volume index; diastolic parameters; strain
The purpose of this prospective, randomized, double-blinded study is to further evaluate the safety and efficacy of varying doses of intravenous magnesium in the treatment of AFF RVR.
Compare the efficacy and safety between pulmonary vein isolation (PVI) alone versus PVI with left atrial (LA) posterior wall isolation (PWI) using pulsed-field ablation (PFA) in the treatment of patients with paroxysmal atrial fibrillation (PAF).
