Does atrial late activation mapping under sinus rhythm predict the critical isthmus in left atrial re-entrant tachycardia?
Atrial isochronal late-activation mapping during sinus rhythm may be a useful approach to predict the critical isthmus of left atrial re-entrant tachycardia.
May support sinus rhythm mapping for LA reentry targets; hypothesis-generating and requires prospective validation.
Functional atrial mapping is an emerging mapping modality to predict potential critical sites with a role in the maintenance of tachycardia. We report a case of atrial late activation mapping under sinus rhythm predicting the critical isthmus of a left atrial tachycardia. Our findings demonstrate the utility of an atrial isochronal late-activation mapping approach to predict the critical isthmus of re-entry.

Yorgun et al. (2023) conducted a case report in Atrial tachycardia (n=1). Isochronal late activation mapping (ILAM) guided ablation was evaluated on Freedom from atrial tachycardia/atrial fibrillation.
