Filter by:The objective of this safety and feasibility study is to assess whether the endocardial creation of electrically nonconductive lesions via PEF catheter ablation applied using the FARAPULSE Cardiac Ablation System Plus is a feasible and safe treatment for PersAF and associated AFL
This is a multi-center, 2-arm, assessor and statistician blinded, pilot randomized controlled trial, to evaluate the effect of catgut embedding in acupoints of Neiguan and Zusanli in reducing early recurrence and improving long-term prognosis in patients with persistent AF after CA..
Today, 50 % of cardiac patients do not participate in cardiac rehabilitation due difficulties in navigating and accessing rehabilitation activities. HeRTA is a partnership project involving Center for Clinical Research and Prevention (CCRP), Hvidovre Hospital, Rehabilitation Center Albertslund and Copenhagen (municipalities), the Danish Heart Association, and local sports associations. A patient advisory board participate throughout the project to ensure a continued focus on patient interests. The overall aim of HeRTA is to develop and test the feasibility of a new, sustainable model for rehabilitation supporting patients to take part in rehabilitation and promoting life-long activity for all patients with heart disease. To ensure equal access to rehabilitation some activities are open to all patients, while others are tailored specifically to patients with vulnerability. The project unfolds in three phases: Development (1. January 1. 2020 - 14. November 2021): Partners and patients co-create content and procedures; Feasibility (15. November 2021 - 31. July 2023): The feasibility of the model is tested, and promising components are identified; Long-term follow-up and implementation (1. August 2023 - 31. December 2025): Long term effects are investigated and promising components are tested in new settings. During the feasibility phase the investigators will examine whether the intervention activities are feasible, acceptable, and may have positive effects for patients with heart disease. The investigators use qualitative data on implementation and acceptability of intervention among partners and patients. An randomisered controlled trial (RCT) component will assess effects on patient participation rates, health, physical activity level, and life quality. Data is collected from practitioners and patients through focus groups, observations, field notes, questionnaires, and interviews. Results will point to: - innovative ways to organize integrated rehabilitation pathways. - approaches to ensuring rehabilitation targeted at patient needs.
This is a prospective, observational, single center pilot trial to find out if a new computerized technology for analysis of the electrical activity recorded during atrial fibrillation can identify the electrical source of this arrhythmia. If we are able to reliably identify the source, then in the future we may be able to use this technology to determine the optimal sites for catheter ablation of atrial fibrillation in the heart. The present study will compare the standard electrical recordings to the new computerized algorithm analysis of recordings gathered at the same time. The study will enroll 30 participants with persistent or longstanding persistent atrial fibrillation (AF) that are scheduled for elective catheter ablation of AF. The catheters that are being placed in the heart are standard Food and Drug Administration (FDA)-approved mapping catheters. The investigational computerized software that will be employed in the trial will be used after the case has done and will not directly impact any of the activities during the ablation procedure. Information learned from this trial will improve understanding of the mechanisms of atrial fibrillation and will potentially improve success rates of AF ablation for patients in the future and will be used to design a prospective trial.
Patients undergoing hybrid AF ablation second stage catheter ablation have the posterior left atrium mapped to see it if is electrically isolated. This is done via a standard electrophysiogical study in accordance with routine clinical practice. Investigators propose to check left atrium posterior wall isolation via oesophageal pacing and compare this to findings from invasive study
This is an open label, randomized parallel control clinical trial, to demonstrate the role of driver mechanism in maintenance substrate of persistent atrial fibrillation with severe atrial fibrosis, and evaluate the clinical outcomes of driver mapping and ablation strategy in patients with persistent atrial fibrillation with severe atrial fibrosis.
The main purpose of this pilot project is to measure the feasibility of conducting a randomized crossover study examining short-term changes in atrial fibrillation (AF) symptoms in symptomatic females and males with paroxysmal or persistent AF when they engage in a standard week of exercise (i.e. moderate-intensity continuous training [MICT] or high-intensity interval training [HIIT]) compared to a control week (i.e. no moderate to vigorous exercise over 7 days).
The primary objective of this study is twofold, first we aim to identify rotors in atrial fibrillation (AF) and analyze their relationship with the left atrium-left atrial appendage (LA-LAA) connections. Secondly, we will analyze the areas harboring rotors in SR to define the characteristics that describe the presence of rotors.
A clinical randomised trial to compare strategies for ablation in persistent and long-standing persistent atrial fibrillation comprising of two arms: pulmonary veins isolation (PVI) only and PVI + individualised mapping-guided ablation (Cartofinder, Biosense Webster Inc.)
Assess the clinical safety and feasibility of MultiPulse Therapy (MPT) electrical stimulation waveform sequence in terminating paroxysmal and persistent atrial fibrillation.
