May aid post-PVI recurrence risk stratification by DE-MRI; leaves open whether targeting gaps improves outcomes.
Does the total relative gap length in pulmonary vein ablation lines assessed by delayed gadolinium enhancement MRI predict AF recurrence in patients after first PV isolation?
Total relative gap length in pulmonary vein ablation lines, detected by delayed gadolinium enhancement MRI, is a significant predictor of atrial fibrillation recurrence at 1 year.
