Omnipolar mapping versus point-by-point mapping approach for catheter ablation of atrioventricular accessory pathway.
J Interv Card Electrophysiol
January 2025
Department of Cardiovascular Medicine, Dokkyo Medical University, 880 Kitakobayashi, Mibu, Shimotsugagun, Tochigi, 321-0293, Japan.
Background: The conventional mapping approach for the atrioventricular accessory pathway (AP) involves point-by-point mapping to identify the connection sites of the AP to the atria or ventricle and accurate interpretation of local electrograms. Omnipolar mapping technology (OMT) explains how vector and wave speed are produced by using both unipolar and bipolar signals to obtain omnipolar signals, directions, and conduction velocity. The aim of this study is to verify the effectiveness of OMT for catheter ablation of AP.

Academic Center for Epileptology (ACE), Kempenhaeghe/Maastricht UMC+, Maastricht & Heeze, Maastricht, The Netherlands.
Objective: To investigate whether local lesions created by stereo-electroencephalography (SEEG)-guided radiofrequency thermocoagulation (RFTC) affect distant brain connectivity and excitability in patients with focal, drug-resistant epilepsy (DRE).
Methods: Ten patients with focal DRE underwent SEEG implantation and subsequently 1 Hz bipolar repetitive electrical stimulation (RES) for 30 s before and after RFTC. Root mean square (RMS) of cortico-cortical evoked potentials (CCEPs) was calculated for 15 ms to 300 ms post-stimulation with baseline correction.
Designing and clinical application of a 3D-printed personalized model of a radiofrequency needle guide with a maxillary fixator for puncture of the gasserian ganglion for trigeminal neuralgia treatment.

1Department of Neurosurgery, I.M. Sechenov First Moscow State Medical University (Sechenov University), Moscow, Russian Federation.
Objective: The purpose of this study was to present a newly designed 3D-printed personalized model (3D PPM) of a radiofrequency needle guide with a maxillary fixation for gasserian ganglion (GG) puncture.
Methods: Implementation of 3D CT-guided radiofrequency therapy of the GG with and without use of 3D PPM was analyzed. The following parameters were assessed: radiation time, dose area product, air kerma reference point, pain severity during the puncture needle insertion, prosopalgia regression degree (according to visual analog scale) and the severity of facial numbness (according to the Barrow Neurological Institute scale) in the early postoperative period, and postpuncture complications.
Dynamic definition liposculpture (HD2) is considered a highly sought after procedure in body sculpting surgery by patients. Radiofrequency microneedling is a cutting edge technology with evidence-based outcomes demonstrating skin tightening and retraction. These ancillary procedures complement and enhance the results of dynamic definition liposculpture.

Objectives: In this study we aimed to educate the reader about providing bipolar RF to various anatomic regions of the face.
Methods: A retrospective review of cases was conducted to assess the safety of zone-specific RF-assisted facial rejuvenation in S.
