Key result
Pentaspline pulsed-field ablation safely achieves simultaneous bilateral superior vena cava isolation without complications.
Why the study?
Persistent left superior vena cava can act as a driver of AF and its isolation may be required in recurrent persistent AF.
Case Report (n=1)
No
This case report provides early evidence that simultaneous isolation of the PLSVC and RSVC using a pentaspline pulsed-field ablation catheter can be safely performed in patients with recurrent persistent AF.
Supports safe dual SVC isolation with PFA in recurrent AF; hypothesis-generating and requires prospective trials before practice change.
Pulsed-field ablation (PFA) is a novel technology for atrial fibrillation (AF) ablation that can deliver energy precisely with a lower risk of damage to the surrounding organs. Persistent left superior vena cava (PLSVC) is a congenital variant that can act as a driver of AF, and its isolation may be required in recurrent persistent AF. We describe a case where PFA was used for isolation of the right superior vena cava, PLSVC, and posterior wall of the left atrium.

Gupta et al. (2024) conducted a case report in Recurrent persistent atrial fibrillation with persistent left superior vena cava (n=1). Pulsed-field ablation (PFA) with a pentaspline catheter was evaluated on Successful isolation of the persistent left superior vena cava and right superior vena cava without AF induction or complications. Simultaneous isolation of the persistent left superior vena cava and right superior vena cava using a pentaspline pulsed-field ablation catheter was safely achieved without complications.
