Network radiofrequency ablation for drug resistant epilepsy

open access: yesEpilepsy & Behavior Reports, 2021
Radiofrequency ablation (RFA) is a minimally invasive procedure for drug-resistant focal epilepsy. Although well tolerated, seizure outcomes are less favorable than standard resection. RFA is commonly performed following stereoencephalography (sEEG) identification of the seizure onset zone (SOZ).

Successful Irrigated-Tip Catheter Ablation of Atrial Flutter Resistant to Conventional Radiofrequency Ablation [PDF]

open access: yesCirculation, 1998
Background —Catheter ablation of typical right atrial flutter is now widely performed. The best end point has been demonstrated to be bidirectional isthmus block. We investigated the use of irrigated-tip catheters in a small subset of patients who failed isthmus ablation with conventional radiofrequency (RF ...

Atrial fibrillation ablation: is common practice far from guidelines' world? The Italian experience from a national survey

open access: yes, 2022
PURPOSE: Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia, occurring in 1-2% of the general population. Catheter ablation has become an important treatment modality for patients with symptomatic drug-refractory AF.
