Pulsed-field ablation for ventricular tachycardia via a retrograde approach resulted in scar homogenization, non-inducibility of VT, and no complications in a single patient.
Case Report (n=1)
Does pulsed-field ablation via a retrograde approach effectively treat ventricular tachycardia in a patient who failed conventional ablation?
This case report provides the first evidence that pulsed-field ablation for ventricular tachycardia via a retrograde approach is feasible and effective.
INTRODUCTION: We present the first worldwide use of pulsed-field ablation (PFA) for ventricular tachycardia (VT) ablation via a retrograde approach. METHODS: The patient had previously failed conventional ablation of an intramural circuit underneath the aortic valve. The same VT circuit was inducible during the procedure. The Farawave PFA catheter and Faradrive sheath were used to deliver PFA applications. RESULTS: Post ablation mapping demonstrated scar homogenization. There was no evidence of coronary spasm during PFA applications and no other complications occurred. VT was non-inducible post ablation and the patient has remained free of arrhythmia at follow-up. CONCLUSION: PFA for VT via a retrograde approach is feasible and effective.
Martin et al. (Tue,) conducted a case report in Ventricular tachycardia (n=1). Pulsed-field ablation (PFA) via a retrograde approach was evaluated on Feasibility, effectiveness, and complications. Pulsed-field ablation for ventricular tachycardia via a retrograde approach resulted in scar homogenization, non-inducibility of VT, and no complications in a single patient.
