Key result
Novel dual-energy linear catheter successfully treats AF and concurrent SVT in 4 cases.
Why the study?
There is limited data on the use of Pulsed Field Ablation for supraventricular tachycardias occurring concurrently with atrial fibrillation.

This case series provides the first evidence that a novel dual-energy linear ablation catheter can successfully treat both atrial fibrillation (via PFA) and concurrent SVT (via RF) in a single procedure.
BACKGROUND: Pulsed Field Ablation (PFA) has emerged as a new energy source for ablation of atrial fibrillation. In approximately 10% of cases, a concurrent Supraventricular Tachycardias (SVT) can also be induced. There is limited data on the use of PFA for SVTs. We report on 4 cases in which SVT was induced during an atrial fibrillation ablation using PFA. In all of these cases, atrial fibrillation was the dominant arrythmia and SVT was either unknown prior to the case or not documented. DISCUSSION: These cases demonstrate how a novel dual energy linear ablation catheter can be used to successfully treat both atrial fibrillation and SVTs. PFA was used to treat atrial fibrillation while Radiofrequency (RF) was used to treat the SVTs. TAKE HOME MESSAGES: This is the first case report of a novel dual energy, linear ablation catheter that can deliver both RF and PFA for the treatment of AF with concurrent SVT.

Sundaram et al. (2026) conducted a case report in Atrial fibrillation and concurrent Supraventricular Tachycardia (SVT) (n=4). Dual-energy linear ablation catheter (PFA and RF) was evaluated on Successful treatment of both atrial fibrillation and SVTs. A novel dual-energy linear ablation catheter successfully treated both atrial fibrillation using pulsed field ablation and concurrent SVT using radiofrequency ablation in 4 cases.
