Observational Study of Atrial Fibrillation Ablation Outcomes

This study, called VIBRANT-AF, is looking for adults aged 18 and older who have undergone a catheter ablation procedure for atrial fibrillation (a type of irregular heartbeat). The goal is to understand what factors lead to successful outcomes and what causes complications after this procedure. You would use a smartphone app and email to answer surveys over one year about your lifestyle, if your atrial fibrillation returns, hospitalizations, and your general feelings. The study aims to identify real-world experiences of patients across the US, not just those in specialized centers. There are no specific interventions being tested in this study; it's about observing and collecting information.

Study design
This is an observational study planning to enroll 1125 participants. It is designed to follow participants over time to collect information.
What's involved
You would connect with the Eureka Research Platform and answer a series of surveys and activities over a one-year period. You will be asked weekly survey questions on habits, complications, medication usage, and hospitalizations.
Compensation
Not stated in the trial record.
Follow-up
Participants will be followed for a period of one year to measure the time until atrial fibrillation returns.
