Why the study?

Atrial infarction is under-recognized, and although most patients have complicated supraventricular tachyarrhythmias, the mechanism remains unknown.

Structured PICO

Population

1 patient (51-year-old man) with atrial tachycardia related to atrial infarction following left circumflex coronary artery occlusion and stenting.

Intervention

Catheter ablation (linear ablation for the cavotricuspid isthmus and defragmentation in the fragmented potential area).

Outcome

Termination of atrial tachycardia and elimination of premature atrial contractions.

Catheter ablation can successfully treat medication-resistant atrial tachycardia arising from atrial infarction.

No takes yet. Share an insight, caveat, or question.

Supports AT ablation in atrial infarction; leaves open mechanism and need for prospective validation.

Fujiwara et al. (2022) studied this question.
