Swiss Atrial Fibrillation Pulmonary Vein Isolation Registry (SWISS-AF-PVI))

February 17, 2025 updated by: University Hospital, Basel, Switzerland
Registry of patients with atrial fibrillation undergoing catheter-based ablation of atrial fibrillation (pulmonary vein isolation) to determine long-term success rates of catheter-based ablation of atrial fibrillation (pulmonary vein isolation) and to evaluate factors associated with long-term success of catheter-based ablation of atrial fibrillation (pulmonary vein isolation).

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
changes in retention rate of normal sinus rhythm after catheter-based ablation of atrial fibrillation (pulmonary vein isolation)
Time Frame: before catheter-based ablation of atrial fibrillation and 3, 6 and 12 months after catheter-based ablation of atrial fibrillation
changes in retention rate of normal sinus rhythm after catheter-based ablation of atrial fibrillation (pulmonary vein isolation)
before catheter-based ablation of atrial fibrillation and 3, 6 and 12 months after catheter-based ablation of atrial fibrillation

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
morphologic changes of left cardiac atrium
Time Frame: before catheter-based ablation of atrial fibrillation (pulmonary vein isolation)
echocardiography of left cardiac atrium
before catheter-based ablation of atrial fibrillation (pulmonary vein isolation)
changes in retention rate of normal sinus rhythm after catheter-based ablation of atrial fibrillation (pulmonary vein isolation)
Time Frame: 12 months after catheter-based ablation of atrial fibrillation and then at intervals of one year until 2035

Other Outcome Measures

Outcome Measure
Measure Description
Time Frame
determination of factors associated with long-term success rates of catheter-based ablation of atrial fibrillation
Time Frame: Blood samples gained during catheter-based ablation of atrial fibrillation (pulmonary vein isolation)
Blood samples (biobanking) for determination of factors associated with long-term success rates of catheter-based ablation of atrial fibrillation (pulmonary vein isolation). Decisions about future analyses to be performed from stored samples will be based exclusively on scientific reasons.
