Key result
Electroanatomic mapping identified a reentry circuit with a protected isthmus in 89% of patients with left atrial macroreentrant tachycardia, and ablation of the isthmus prevented recurrence.
Why the study?
Can electroanatomic mapping identify reentry circuits with protected isthmuses in patients with left atrial macroreentrant tachycardia, and are they amenable to radiofrequency ablation?
Observational (n=28)
Can electroanatomic mapping identify reentry circuits with protected isthmuses in patients with left atrial macroreentrant tachycardia, and are they amenable to radiofrequency ablation?
Electroanatomic mapping effectively identifies protected isthmuses in left atrial macroreentrant tachycardia, allowing for successful radiofrequency ablation that prevents recurrence when conduction block is achieved.

May facilitate targeted ablation in left atrial macroreentrant tachycardia; leaves open validation in prospective cohorts.
Ouyang et al. (2002) conducted an observational in Left atrial macroreentrant tachycardia (LAMRT) (n=28). Electroanatomic mapping and radiofrequency ablation was evaluated on Identification of reentry circuit with a protected isthmus. Electroanatomic mapping identified a reentry circuit with a protected isthmus in 89% of patients with left atrial macroreentrant tachycardia, and ablation of the isthmus prevented recurrence.
