Filter by:Atrial fibrillation (AF) is the commonest condition affecting the rhythm of the heart. Tablets to try to normalize the heart rhythm rarely work well. As a result, doctors have devised a treatment called catheter ablation in which special wires are used to deliver heat energy (called ablation lesions) on the inside surface of the heart. Unfortunately, in many patients (almost 1 in 2), some of these ablation lesions recover, and that leads to the recurrence of AF. Many of these patients then need a second procedure to deliver further ablation at these recovered areas. Because of that problem, a software called Ablation Index has been developed to optimize the delivery of ablation lesions. The study aims to find out the effectiveness of the use of that Ablation Index in improving the ablation outcomes in patients with persistent AF. Also, the study will test the effectiveness of a new ablation approach using a catheter which is capable of delivering high-power during ablation and therefore requires shorter time for ablation. This will be achieved by following up patients who received ablation for 12 months to monitor their response to treatment in terms of freedom from AF. This study will include patients with persistent AF which means AF episode(s) that last for longer than seven days. Patients participating in the study will undergo their ablation treatment either guided by ablation Index or delivered using high-power, short-duration (HPSD) ablation. All participants will undergo implantation of a cardiac monitor, also knowns as loop recorder, to monitor for recurrence of atrial tachyarrhythmia following ablation. The monitor stores these ECG recordings which will be downloaded during review appointments that will be arranged 6 weeks, 3 months, 6 months and 12 months after the ablation procedure.

This study is aimed to evaluate the Efficacy and Safety of Pulsed Field Ablation (PFA) in Patients with Paroxysmal Atrial Fibrillation (PAF)
The overall objective of this proposal is to evaluate the feasibility of a comprehensive digital atrial fibrillation (AFib) management tool that will empower patients to a) take an active role in learning about AFib management options, starting and adhering to evidence-based therapies and lifestyle changes and b) to guide the patients during AFib episodes which are associated with anxiety and impairment in quality of life. Researchers plan to evaluate the feasibility and preliminary efficacy of this novel digital toolkit in improving quality of life and decreasing AFib burden in a pilot randomized clinical trial (RCT).
This prospective randomized trial aims to compare recovery time from discontinuation of remimazolam followed by flumazenil administration vs. propofol total intravenous anesthesia as the main general anesthetics during radiofrequency catheter ablation treatment of atrial fibrillation.
The investigators hypothesized that PeAF-by-LAWT, a personalized protocol that uses a contact-force catheter, a multichannel radiofrequency (RF) generator, and integrated LAWT information to adapt the ablation index (AI) target to the subjacent LAWT, is safe, while showing at least the same efficacy and better efficiency than the CLOSE protocol for persistent AF ablation.
The primary objective of CONVERGE PAS is to evaluate clinical outcomes (peri-procedural and long-term) in a cohort of patients treated during commercial use of the EPi-Sense® Guided Coagulation System or EPi-Sense ST™ Coagulation System to treat symptomatic long-standing persistent atrial fibrillation (AF) patients who are refractory or intolerant to at least one Class I and/or III AAD.
The primary objective of the study is to reduce hospital admission and decrease time to disposition through establishing an effective treatment protocol for AF and Atrial Flutter in the Emergency Department of Spectrum Health Lakeland. Secondary outcome is to measure if oral diltiazem is an effective HR controlling agent in AF RVR and Flutter.
The Swiss-AF-BURDEN study will be embedded in the follow-up visits of the Swiss-AF cohort study. The research question of the current atrial fibrillation burden will be answered by using 7-day Holter-ECG recordings and continuous implanted loop recorder recording, whereas cardiac MRI examination will give results about cardiac dimensions and function. The 7-day Holter ECG will be repeated after one year. The cMRI will be performed separately or directly after the brain MRI to minimize the additional burden for the patients. Only a subsample of 100 patients will additionally receive ILR for 2 years.
Treatment recommendations and guidelines for patients with atrial fibrillation (AF) are continuously changing. The role of catheter ablation in the treatment of AF increases and the techniques of the procedures are improving unceasingly. Responding to and evaluating the effect of these changes requires careful examination of this patient population and procedure outcomes. The aim is to create a clinical characterization platform for patients scheduled for AF ablations with the purpose to optimize health care processes and related translational research.
The outcomes regiStry for non-vitamin k antagonist oral anticoagUlants treatmeNt in variouS tHrombotIc dIseases for better cliNical practicE (SUNSHINE) is a multicenter, prospective, observational non-interventional inpatient/outpatient disease registry to assess the utilization of Non-vitamin k antagonist oral anticoagulants (NOACs), and associated outcomes. The SUNSHINE registry will focus on the collection and analysis of observational data in medical records from hospital information system (HIS) to evaluate the outcomes related with these NOACs when applied in extensive patient populations outside of clinical research studies. The registry will also allow for mainly combining the atrial fibrillation (AF) and venous thromboembolism (VTE) databases. In brief, the SUNSHINE registry will provide important information on the outcomes of NOACs in routine practice and gather further information on its safety and effectiveness.
