Pulsed field ablation (PFA) is described as non-thermal, but data from oncology and cardiology show thermal effects occur. The specific waveform parameters influencing energy development during PFA are unclear. aim of this study to numerically evaluate the on myocardial oesophageal tissue at various peak voltage conditions. A three-dimensional computer model left atrium quantified voltages 1, 1.5, 2 kV. Energy was applied using a bipolar configuration with far-field symmetry boundaries set...
Proactive cooling with a novel device has been shown to reduce endoscopically identified thermal injury during radiofrequency (RF) ablation for the treatment of atrial fibrillation using medium power settings. We aimed evaluate effects proactive high-power short-duration (HPSD) ablation.
Abstract Background and Aims Pulsed field ablation (PFA) has been described as non-thermal, but abundant data exist in oncology applications, growing are emerging cardiology, highlighting that thermal effects fact present with PFA. Our objective was to develop a reliable model of the arising from PFA myocardial esophageal tissue over range typical peak voltage operating conditions. Methods We developed three-dimensional computer left atrium can quantify applications. Energy applied using...
Abstract Background and Objectives Laser ablation is increasingly used to treat atrial fibrillation (AF). However, atrioesophageal injury remains a potentially serious complication. While proactive esophageal cooling (PEC) reduces during radiofrequency ablation, the effects of PEC laser have not previously been determined. We aimed evaluate protective AF by means theoretical study based on computer modeling. Methods Three‐dimensional mathematical models were built for 20 different cases...
