[EN] This review begins with a rationale of the importance of theoretical, mathematical and computational models for radiofrequency (RF) catheter ablation (RFCA). We then describe the historical context in which each model ...
Purpose: The aim was to study by computer simulations the insulating role of the reactive
zone surrounding a cortical osteoid osteoma (OO) in terms of electrical and thermal
performance during radiofrequency ablation ...

[EN] Purpose:Most modeling studies on radiofrequency cardiac ablation (RFCA) are based on limited-domain models, which means the computational domain is restricted to a few centimeters of myocardium and blood around the ...
[EN] Purpose Stellate ganglion (SG) block by thermal radiofrequency ablation (RFA) is frequently conducted as a therapeutic intervention for sympathetic-maintained and neuropathic pain syndromes. RFA's partial lack of ...

[EN] Introduction: During radiofrequency ablation (RFA) using conventional RFA catheters (RFC), similar to 90% of the energy dissipates into the bloodstream/surrounding tissue. We hypothesized that a novel insulated-tip ...
