Key result
Left atrial anterior linear ablation for persistent atrial fibrillation led to the development of an iatrogenic single-loop biatrial macro-reentrant tachycardia in one patient.
Why the study?
Data concerning the proarrhythmic role of left atrial anterior or septal-anterior linear ablation lesions in producing biatrial macro-reentrant tachycardia are lacking.
Case Report (n=1)
Left atrial anterior linear ablation for persistent atrial fibrillation can be proarrhythmic, potentially leading to iatrogenic single-loop biatrial macro-reentrant tachycardia.
May induce iatrogenic biatrial macro-reentry after persistent AF ablation; hypothesis-generating for lesion-set safety.
Biatrial macro-reentrant tachycardia (Bi-MAT) is a relatively uncommon arrhythmia. Sometimes, it can be produced by the left atrial (LA) anterior or septal-anterior linear ablation. However, data concerning the proarrhythmic role of this ablation lesions are lacking. Here, we reported a case of a single-loop Bi-MAT developing after the LA anterior ablation line performed in one patient with persistent atrial fibrillation.

Zhou et al. (2020) conducted a case report in Persistent atrial fibrillation (n=1). Left atrial anterior ablation line was evaluated on Development of single-loop biatrial macro-reentrant tachycardia (Bi-MAT). Left atrial anterior linear ablation for persistent atrial fibrillation led to the development of an iatrogenic single-loop biatrial macro-reentrant tachycardia in one patient.
