Multimodal Cardiac Imaging Registry in Patients with Atrial Fibrillation
The goal of this observational registry is to collect a curated dataset of multimodal imaging data that will serve for development of artificial-intelligence based solutions for prediction of risk and outcomes in patients with atrial fribrillation. Type of study: observational study Study Participants: Patients with atrial fibrillation or atrial flutter …
PROSPective Evaluation of Outcome After CatheTer Ablation in Atrial Fibrillation
Atrial fibrillation ablation is the most common intervention performed worldwide. Up to 20 to 45% of patients show recurrence of AF within 12 month after catheter ablation, however its determinant are incompletely understood. The aim of the PROSPECT-AF study is to assess the predictors of AF recurrence within the 3 …
Multicenter Registry of Atrial Fibrillation Ablation With Radiofrequency Balloon Catheter
All consecutive patients with paroxysmal or persistent atrial fibrillation undergoing pulmonary vein isolation with the radiofrequency balloon catheter (RFB) "Heliostar" (Biosense Webster) will be included in a multicenter observational registry. The aim of the study is to assess the safety and arrhythmic outcome of atrial fibrillation ablation with the RFB …
Thromboembolic and Bleeding Risk Stratification in Patients With Non-valvular Atrial Fibrillation
The aim of the present prospective study is to further develop and validate a composite risk score predicting both ischemic and bleeding risk, based on epidemiologic, clinical, biological, and/or morphologic complementary data. First, the investigators will assess the predictive performance of current clinical risk scores. Second, the investigators will assess …
Volunteers to Investigate Best Results for Ablation and Novel Therapies for Atrial Fibrillation
VIBRANT-AF seeks to: Identify clinically relevant predictors of effectiveness and complications of AF ablation procedures in a prospective, US-based, multi-center, real-world longitudinal study Assess changes in modifiable lifestyle-related exposures influence the effectiveness of AF ablation Determine incidence and predictors of complications of AF ablation procedures Participants will connect with the …
Left Atrial Appendage Closure as Secondary Prevention of Atrial Fibrillation-related Embolic Events
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 …
The Evaluation for Prognostic Factors After Catheter Ablation of Atrial Fibrillation: Cohort Study
Purpose of the study To explore clinical recurrence associated clinical factors including age, sex, clinical, electrophysiological, anatomical, imaging, and serologic characteristics. To develop simulation model to predict clinical recurrence and the efficacy of catheter ablation 2. Scientific evidence of the study In atrial fibrillation patients, the maintenance of normal sinus …
The Multi-center Study of Comprehensive Atrial Fibrillation Regurgitation and Recurrent Events Evaluation
Atrial fibrillation (AF) is the most common cardiac arrhythmia in the clinic and can lead to valve regurgitation and a poor prognosis. At present, atrial fibrillation ablation is one of the most effective means for the recurrence of atrial fibrillation in clinical practice, but the recurrence rate is high. Therefore, …
Prediction of UA/SOD Ratio as a Biomarker of Oxidative Stress in Atrial Fibrillation
To clarify the predictive effects of uric acid and superoxide dismutase as biomarkers of oxidative stress on atrial fibrillation, and to provide greater value for the diagnosis and prediction of atrial fibrillation. It provides a new idea for the prevention and treatment of atrial fibrillation.
Risk Factors for Stroke or Systemic Embolism in Chinese Patients with Non-Valvular Atrial Fibrillation Registry
This study is aimed to validate the existing stroke risk stratification model for patients with atrial fibrillation (AF) (CHA2DS2-VASc Score, CHADS2 Score, ATRIA score, ABC score, etc.) and establish a new stroke risk assessment model using a nationwide AF -specific registry in China.
