First reported balloon-in-basket pulsed field ablation in a patient with long-standing persistent atrial fibrillation and a mechanical mitral valve prosthesis
The authors report what appears to be the first use of the Volt balloon-in-basket pulsed field ablation system in a patient with long-standing persistent atrial fibrillation
In a 64-year-old patient, 16 pulsed field ablation applications enabled isolation of all four pulmonary veins. No phrenic nerve injury, pericardial effusion, or deterioration of prosthetic valve function was observed. During 194 days of follow-up, no recurrence of atrial arrhythmia was reported.
This single case supports the technical feasibility of the procedure, but larger studies are needed to determine its safety, durability, and comparative effectiveness in patients with mechanical hear
