ClinConnect Summary

This clinical trial is studying the effects of a procedure called catheter ablation on patients with certain heart rhythm problems, specifically atrial fibrillation and atrial flutter. The goal is to see how this procedure affects two specific risk scores related to stroke and bleeding, known as the ABC scores. This trial is looking for adults aged 18 and older who are experiencing symptoms from these heart conditions and are scheduled for their first catheter ablation. Participants will need to provide informed consent to join the study.

Once enrolled, participants will have blood samples taken at different times: before the procedure and again at 3, 6, and 12 months afterward. They will also be monitored closely for any possible recurrence of their heart rhythm issues using various devices, including an implanted monitor and possibly a smartwatch or smartphone. Through this trial, researchers hope to learn more about how effective catheter ablation is in reducing the risk of stroke and bleeding, as well as which monitoring methods work best after the procedure.
