Clinical Study on the Effect of CPAP on AF Recurrence After Catheter Ablation in Patients with AF and OSA
Atrial fibrillation (AF) is the most common sustained arrhythmia in clinical practice, significantly increasing the risks of death, stroke, heart failure, cognitive impairment, and dementia, thus severely impacting patients' quality of life. However, for AF patients with concomitant cardiovascular risk factors, particularly those with obstructive sleep apnea (OSA), the success …
Stroke Risk Assessment and Markers of Blood Clotting in Patients With Newly Diagnosed Non-valvular Atrial Fibrillation (NVAF), Who Have Not Received Oral Anticoagulation Therapy (OAC-therapy) Prior to Inclusion
Background Atrial fibrillation (AF) is the most common heart rhythm disorder worldwide. Globally, there are 37.5 million people with AF. AF increases the risk of death, heart failure, and stroke, which severely affect patients and also lead to high healthcare costs. Around 25% of all strokes are caused by AF, …
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.
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.
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 …
The Impact of Atrial Pressure Change Before and After Combined Procedure
One-stop procedure combining catheter ablation (CA) and left atrial appendage closure (LAAC) has been a feasible treatment for patients with atrial fibrillation at high risk of stroke and/or bleeding. Although it could achieve considerable rhythm control and stroke prophylaxis, a number of patients has experienced progressive heart failure after the …
Registry of Atrial Arrhythmia Ablation Procedures Using Pulsed Field Ablation in Poland
The aim of the described project is to establish a multicenter, nationwide registry of atrial arrhythmia ablation procedures using the Pulsed Field Ablation (PFA) method. These procedures have only recently begun to be performed in several centers across Poland. With proper coordination of the registry, this will enable the consolidation …
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: …
Outcomes and Safety of Various Conduction System Pacing Methods
The aim of this study is to evaluate safety and clinical outcomes after different pacing approaches of conduction system pacing in a prospective registry.
Defining the Risk of Ventricular Tachycardia in Genetic Cardiomyopathies
The goal of this observational study is to determine if electrophysiologic mapping and cardiac MRI can help identify patients that have genetic forms of cardiomyopathy that are at high risk for development of dangerous ventricular arrhythmias. The investigators aim to study: the prevalence and mechanism of inducible ventricular tachycardia pace-mapping …
