Key result
ICE detects atrial tachycardia originating from a persistent left superior vena cava during AF ablation.
Why the study?
Non–pulmonary vein triggers, such as those originating from a persistent left superior vena cava, are important drivers of atrial fibrillation in a subgroup of patients and require targeted ablation strategies.

Persistent left SVC may harbor non-PV AF triggers; leaves open whether routine SVC mapping improves ablation outcomes.
Case Report (n=1)
Highlights a case of non-pulmonary vein triggers for atrial fibrillation originating from a persistent left superior vena cava detected via intracardiac echocardiography.
Abrich et al. (2017) conducted a case report in Atrial fibrillation / atrial tachycardia with persistent left superior vena cava (n=1). Atrial fibrillation ablation was evaluated. A patient undergoing atrial fibrillation ablation was found to have an atrial tachycardia originating from a persistent left superior vena cava detected during intracardiac echocardiography.
