ClinConnect Summary

This clinical trial is studying how well certain heart imaging tests can help doctors understand and predict the return of atrial fibrillation (AF) after a treatment called ablation. AF is a common heart rhythm problem that can cause leakage in heart valves and lead to serious health issues. The study uses special 3D ultrasound scans to look closely at the heart’s structure and how well the valves are working. By combining two types of 3D heart scans, researchers hope to find signs that show who might have AF come back after ablation, which could help tailor better treatments in the future.

Adults aged 18 and older who have atrial fibrillation and plan to have an ablation procedure may be able to join the study. Participants will undergo these detailed heart scans before their treatment. The study will not include people with certain other heart conditions, recent strokes or heart attacks, or those who have had previous ablation procedures. If you take part, you can expect to have these non-invasive ultrasound tests as part of your care, helping doctors gather important information about your heart to improve treatment outcomes.
