Key result
Multipolar mapping catheter insertion during AF ablation triggers transient ST-segment elevation via inter-atrial septal stretch.
Why the study?
ST-segment elevation is a very rare complication observed during various cardiac ablation procedures.

No
Transient ST-segment elevation during AF ablation can occur due to inter-atrial septal stretch from catheter manipulation, mimicking acute coronary injury but resolving spontaneously.

Recognize septal stretch as a benign cause of transient ST elevation in AF ablation to avoid misdiagnosis; case reports leave open true incidence.
ST-segment elevation (STE) is a very rare complication observed during various cardiac ablation procedures. We report an interesting case of transient STE elevation by inter-atrial septal stretch during introduction of a multipolar mapping catheter during pulmonary vein isolation procedure. We also discuss various mechanisms for this observation.

Kanjwal et al. (2023) conducted a case report in Atrial fibrillation (n=1). Multipolar mapping catheter introduction was evaluated on Development of ST-segment elevation. Introduction of a multipolar mapping catheter during atrial fibrillation ablation caused transient ST-segment elevation due to inter-atrial septal stretch, which resolved without coronary injury.
