Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

This study explores the relationship between myocardial fibrosis and patient outcomes in Atrial Fibrillation (AF), specifically after catheter ablation. It aims to use Cardiac CT, an accessible tool, to measure left ventricular extracellular volume (ECV) as an indicator of fibrosis. The study will assess if higher ECV levels correlate with increased risks of AF recurrence, hospitalization, and poor cardiac function recovery. Positive findings could make ECV a key factor in deciding AF treatment strategies.
