Overview

Study reveals persistent dysfunction in atrial and biventricular structures correlates with AF recurrence, suggesting improvement in CMR evaluations.

Key Points

  • AF recurrence is linked to persistent atrial and biventricular dysfunction after catheter ablation.
  • Patients with recurrence showed significantly impaired atrial function and prolonged LV T1/T2 times compared to non-recurrence.
  • A combined model using CMR markers improved prediction of AF recurrence at one year of follow-up.
  • The study indicates the potential role of CMR-derived measures in enhancing risk stratification for patients undergoing catheter ablation.
