Active clinical trials for "Atrial Fibrillation"

This registry is performed for the long-term assessment of outcome, performance and residual safety aspects of the BIOMONITOR III and possible successors in a real-life clinical set-up. In addition, this registry is set up in a way that it may also be used as a platform for submodules to investigate additional scientific and regulatory aspects while minimizing the additional effort for the investigational sites and patients.

This study aims to identify genetic causes of adverse events after cardiac surgery, such as atrial fibrillation, myocardial infarction, renal dysfunction and heart failure. Patients undergoing heart surgery at Brigham and Women's Hospital and Texas Heart Institute are eligible to participate.

This is a Prospective, controlled, single-blind, randomized (2:1, Intervention:Control) clinical trial. The purpose of the study is to determine the role of adjunctive renal sympathetic denervation in the prevention of Atrial Fibrillation (AF) recurrence in patients with hypertension scheduled for a redo AF ablation procedure for paroxysmal or persistent AF. Patients will be randomized to either i) AF ablation (Control) or ii) AF ablation + renal sympathetic denervation (Intervention).

Enrolled subjects will be treated with the Synaptic Cryoablation System. Treatment will include cryoablation of the pulmonary veins to achieve PVI. All subjects will be followed for twelve (12) months after completion of the index ablation procedure.

Cardiology Research Dubrava registry is a prospective, single centre registry including patients with acute coronary syndrome with and without ST segment elevation, patients with heart failure who were introduced with SGLT-2 inhibitors, patients implanted with TAVI, patients with venous thromboembolism, patients with pulmonary embolism who underwent thromboaspiration procedure, patients implanted with ICD, CRT and conduction system pacing devices, as well as patients with atrial fibrillation who underwent pulmonary vein isolation and are prescribed with long-term anticoagulation therapy.

This study aims to investigate the best strategy for repeat ablation of recurrent persistent atrial fibrillation (AF) after previous persistent AF ablation involving pulmonary vein isolation (PVI) along. Patients with low voltage areas on the posterer wall will be randomized to PVI alone or the posterer wall isoaltion (PWI) in addition to PVI.

Our study will include consecutive patients undergoing pulsed field ablation (PFA) or cryoballoon (CBA) ablation. Tissue injury and inflammation markers will be measured before and after the procedure.

The goal of this randomized double blind controlled trial is to learn about the effects of calcium when it is given prior to diltiazem for patients with atrial fibrillation ( a type of irregular heart beat) who have rapid ventricular response ( a pulse over 100 beats per minute). Normally diltiazem 0.25mg/kg (max 20mg) is given to slow the heart rate. We will give Placebo versus Calcium Gluconate 2gm given prior to diltiazem. The main questions it aims to answer are: Does calcium decrease the incidence of low blood pressure (a side effect of diltiazem)? How does calcium effect the action of diltiazem? Does it interfere with the desired decrease in heart rate? Participants will receive either placebo or calcium immediately prior to the administration of diltiazem. Their blood pressure and pulse will be measured: prior to study drug administration post study drug and prior to diltiazem administration 3 minutes post start of diltiazem 5 minutes post start of diltiazem 10 minutes post start of diltiazem 20 minutes post start of diltiazem 30 minutes post start of diltiazem Researchers will compare the placebo group to the calcium group to see if there is a difference in the blood pressure and pulse.

The aim of the present study is to prospectively evaluate the safety of Edoxaban.

This clinical study is a prospective, multi-center, non-interventional study designed to investigate the safety and effectiveness of percutaneous LAA appendage closure by using LAmbre™ Left Atrial Appendage Occluder System. 579 patients with valvular AF complicated with previous AF-related embolic events (including ischemic stroke, TIA and systemic embolism) were enrolled at about 20 study sites nationwide. The baseline data, operation process and relevant follow-up information of subjects were recorded at 7 months after operation or before discharge and at 1, 3, 6, 12 and 24 months after operation.
