Update on high-power short-duration ablation for pulmonary vein isolation
Autor: Yan Wang, Mei Hu, Guangzhi Chen, Jie Qiu, Dao Wen Wang
Publikováno v: Journal of cardiovascular electrophysiologyREFERENCES. 31(9)
Pulmonary vein isolation (PVI) is the cornerstone of atrial fibrillation (AF) ablation. However, this procedure remains complex and time-consuming, and the recurrence of AF after PVI is still unsatisfactory. Current technologies have improved our kno

Publikováno v: Circulation: Arrhythmia and Electrophysiology. 12
Background: Radiofrequency ablation of intramural ventricular substrate is often limited by insufficient tissue penetration despite high energy settings. As lesion dimensions have a direct and negative relationship to impedance, reducing the baseline

Electrogram Characteristics of Ablated and Non-Ablated Myocardium in Humans: A Comparison of Miniaturized Embedded Electrodes and Conventional Ablation Electrodes
Autor: Michael H. Hoskins, Michael Lloyd, Jonathan J. Langberg, Anand D. Shah
Publikováno v: Journal of Cardiovascular Electrophysiology. 27:820-824
INTRODUCTION Intracardiac electrogram voltage remains an important metric for radiofrequency lesion application. Embedded micro-electrodes within ablation catheters are now approved for use in humans. OBJECTIVE This study examined electrogram charact

Electrogram voltage and pacing threshold before ablation, measured by mini-electrodes, predict parameters indicative of transmural lesions in the human atrium
Autor: Mercedes Ortiz, Teresa Barrio-López, Carla Lázaro, Martín Arceluz, Jesús Almendral, Eduardo Castellanos
Publikováno v: Journal of Interventional Cardiac Electrophysiology
Purpose An important attenuation of the atrial signal recorded with mini-electrodes (ME) embedded in an 8-mm tip was associated with a transmural radiofrequency lesion. Our aim was to assess if parameters obtained from ME or conventional bipoles befo
