Austrian Left Atrial Appendage Closure Registry
Left atrial appendage (LAA) occlusion (LAAC) has been introduced to treat patients with indication of oral anticoagulation (OAC) for atrial fibrillation (AF) with contraindication to OAC. This registry aims to document all LAAC procedures in Austria.
Rhythm Express Wearable System vs. Simultaneous Polysomnography for the Diagnosis of Obstructive Sleep Apnea in Adults With Suspected or Observed Atrial Fibrillation
The goal of this observational study is to confirm the accuracy of the sleep algorithm (software) used in the Rhythm Express Wearable System to detect sleep apnea severity. The study involves participants wearing the RX-1 mini cardiac monitor on their chest and a pulse oximeter during a traditional sleep test, …
Cerebral Embolization During Pulmonary Vein Isolation
The goal of the TCD-CA study is to determine the frequency of cerebral embolization during pulmonary vein isolation using continuous transcranial Doppler examination. Different parts of the procedure, different ablation techniques and periprocedural anticoagulation regimes will be compared.
The Cardio-share Telemedicine Cross-sector Collaboration Model for Managing Vulnerable Patients With Heart Failure
The goal of this observational study is to explore the potential of implementing a telemedicine-based cross-sector collaboration model to manage patients with frequent admissions with decompensated heart failure. The main question(s) it aims to answer are: Characterization of conditions that make these patients vulnerable Description of key-elements that makes possible …
Inflammatory Response Following " Pulsed Field Ablation " vs. Radiofrequency Ablation-2
Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia. Catheter ablation using pulmonary vein isolation (PVI) in an established treatment strategy for AF. Pulsed Field Ablation (PFA) is a non-thermal ablation modality which has recently been introduced in clinical practice with the aim of improving PVI efficacy and safety. …
Outcome of Overweight AF Patients Following Ablation With a Potential Weight Loss Medication ( GOAL-AF )
Atrial Fibrillation (AF) is the most common abnormal heart rhythm(arrhythmia) affecting about one in 40 people in England. Patients with AF often have symptoms ranging from palpitations and breathlessness, and a small number of patients may develop heart failure. The major complication of AF is stroke, and this is effectively …
Stand-alone Left Atrial Appendage Occlusion for Thromboembolism Prevention
This prospective nationwide registry aims to assess the durability of left atrial appendage occlusion when performed via totally thoracoscopic, percutaneous and hybrid- minimally invasive approaches and collect information on possible adverse events.
Stepwise Screening for Silent Atrial Fibrillation After Stroke
The main hypothesis of this work is that an approach combining clinical parameters and biomarker assays could improve the understanding and prediction of the occurrence of silent atrial fibrillation (AF) in the acute phase after stroke. In this prospective work, the investigators will rely on the Dijon Stroke Registry, which …
Exercise Capacity Before and After AF Ablation in Patients With HFpEF
In a prospective, observational pilot study of patients scheduled for an atrial fibrillation (AF) ablation at the University of Vermont Medical Center the investigators will compare exercise capacity before and four months after AF ablation.
Atrial Functional Mitral Regurgitation and Tricuspid Regurgitation
A prospective, observational cohort study designed to identify clinical phenotypes and evaluate predictors & outcomes of functional mitral and tricuspid valve regurgitation in patients with atrial fibrillation. Participant will under go: Baseline echocardiography Cpex Echocardiography Blood test: BNP 1 year follow up Echocardiography Participants will be stratified into three subgroups: …
