Arrhythmia Recurrence After Atrial Fibrillation Ablation: Can Magnetic Resonance Imaging Identify Gaps in Atrial Ablation Lines?
Why the study?
Does three-dimensional delayed enhancement magnetic resonance imaging identify gaps in atrial ablation lines compared to invasive electro-anatomical mapping in a patient with recurrent atrial arrhythmia?
Population
1 patient with recurrent atrial arrhythmia after multiple unsuccessful ablations for atrial fibrillation
Comparison
Three-dimensional delayed enhancement magnetic… vs Invasive electro-anatomical mapping

Implication
May support noninvasive gap detection post-ablation in recurrent arrhythmia; hypothesis-generating, requiring prospective validation before clinical adoption.
