Filter by: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).
This is a prospective, randomized controlled, single-blind, multi-center clinical trial study aiming to investigate whether the strategy of posterior wall isolation (PWI) assisted by vein of Marshall ethanol infusion (VOMEI) could improve the success rate of persistent atrial fibrillation ablation.
Based on the data of inpatients with hypertension and a cross-sectional study with a large sample size, this study aims to find the early warning value of the left anteroposterior atrial diameter for the possible occurrence of atrial fibrillation in patients with hypertension, and compare the advantages and disadvantages of the above two methods for the early warning of the risk of atrial fibrillation in patients with hypertension, so as to achieve the purpose of early identification of high-risk groups that may develop atrial fibrillation.
Despite a clear definition in the European Society of Cardiology (ESC) guidelines, the differentiation between paroxysmal (self-terminating) and persistent (nonself- terminating) atrial fibrillation (AF) remains challenging in clinical practice. Some patients with presumed persistent AF are planned for electrical cardioversion (ECV) but appear to have a paroxysmal pattern or present in sinus rhythm (SR) at the scheduled ECV appointment. This results in unnecessary visits or interventions for patients, and costs and burden for the hospitals and health insurances. Based on the feasibility of the TeleCheck-AF approach, which is an on-demand mobile health (mHealth) infrastructure incorporating app-based heart rate and rhythm monitoring to support remote AF management through teleconsultation, the investigators aim to extend this mHealth approach to the management of presumed persistent AF patients planned for ECV.
