Description
F Notaristefano and co-authors test whether focal pulsed field ablation can be tolerated under local anesthesia alone, in a 2026 study. Single shot devices usually demand general anesthesia because their pulses trigger muscle contraction, while the newer dual energy focal catheter was expected to recruit less muscle. Twenty-four patients with persistent fibrillation received pulsed field energy at the back of the left atrium for vein isolation and a floor line, with every symptom logged by site.
No muscle contractions appeared. Cough struck about two thirds of patients, most often at the left upper vein, and patients who coughed there had shorter distances between that vein and the nearest airway branch. Pain also affected about two thirds, without any link to esophagus position on scans. Switching a few applications to radiofrequency solved symptoms, and isolation succeeded in everyone with no acute complications. The authors call the approach feasible and safe.
