Active clinical trials for "Atrial Fibrillation"

EQUAL-AF is an observational feasibility study which will determine if there is a long-term effect of bleeding for patients diagnosed with AF, who are taking anticoagulants. The investigators will use three validated questionnaires/PROMs (AFEQT, EQ5D-3L, and PACT-Q) to gather data from a patient perspective. Patients will complete all questionnaires no more than 4 weeks following a bleed and a second time 3 months later. As this study tests feasibility, progression criteria will apply. The primary objective is to assess recruitment success to ensure that the patient population is accessible and willing to engage with the research team. Additionally, the investigators will look to identify the need for a specific bleeding PROM which will assess long-term quality of life impact for patients experiencing bleeds while anticoagulated.

The goal of this retrospective registry is to evaluate the efficacy and safety of Refralon®, concentrate for solution for intravenous injection, as chemical cardioversion in patients with paroxysmal and persistent atrial fibrillation and flutter in routine clinical practice. The main questions it aims to answer are: What is the incidence of sinus rhythm restoration within 6 hours in patients with paroxysmal atrial fibrillation (AF)/atrial flutter (AFL) after the first dose of Refralon®? What is the incidence of sinus rhythm restoration within 24 hours in patients with persistent AF/AFL after the first dose of Refralon®?

The purpose of the study is to confirm the Garmin ECG (electrocardiogram) software algorithm can detect and classify atrial fibrillation and normal sinus rhythm on single lead ECG data derived from a Garmin wrist-worn, consumer device. The study will also confirm the software's ability to create a Lead I ECG that is clinically equivalent to a reference device. The Garmin ECG software is not a diagnostic system and is intended for informational purposes only.

The purpose of the study is to evaluate the efficacy of abbreviated 3-day anticoagulation with dabigatran etexilate before cardioversion guided by trans-oesophageal echocardiography in comparison with conventional 3- week course of dabigatran etexilate before cardioversion

The purpose of the study is to evaluate the safety and effectiveness of Xarelto in renally impaired patients with NVAF under routine practice conditions. The information collected in the XARENAL study will help to understand how renally impared patients with NVAF are treated in the real-world setting and what the outcome for the patients is under those conditions.

Atrial fibrillation in the postoperative period of myocardial revascularization surgery (AF-POMR) occurs in 10% to 65% of patients, increasing morbidity and mortality after surgery. is associated with an increase in hospital length of stay, and, thus, in costs,and can cause serious clinical complications, such as hypotension, heart failure, stroke and other thromboembolic disorders.Although not completely understood, the electrophysiological mechanism of AF-POMR is believed to be reentry.

The purpose of this registry is to assess the performance and clinical effectiveness of a combination of SJM mapping and ablation products in the treatment of subjects with atrial fibrillation (AF).

The aim of this study is to evaluate the present status of stroke prevention strategies in patients with non-valvular atrial fibrillation (NVAF). Vitamin K antagonists (VKAs) have been the only available oral anticoagulant therapy for decades. Recently novel oral anticoagulants have emerged as an alternative for VKAs. This study is planned to evaluate the epidemiological characteristics, thromboembolic and bleeding risks, stroke prevention strategies and appropriateness of oral anticoagulant use in NVAF patients. Time in therapeutic range (TTR) is going to be calculated as the percent of visits in range (2-3) for warfarin patients. This is a national multicenter observational study in which Turkey is divided into seven regions. A proportional number of patients to the population of every region is planned to be included.

The study is designed to collect data of the performance and confirm the safety of the DX (Diagnostic eXtension) functionality in the Lumax 640/470 HF-T in patients with permanent atrial fibrillation and CRT-D indication according to current ESC guidelines. The DX functionality is a feature, which can be activated in the Lumax 640/740 HF-T when connected to the LinoxSMART S DX right ventricular lead. The combination of these devices enable atrial sensing via a sensing dipole in the ventricular lead and therefore reduces the number of implanted leads without sacrificing atrial information. Atrial pacing can not be provided but is not needed in patients with permanent atrial fibrillation.

The purpose of this study is to check if at 1 year after surgical ablation the electrical impulses that cause atrial fibrillation (AF) are still blocked from being able to get into the heart. Hypothesis Conduction block and ganglionic destruction are required for freedom from AF.
