[EN] It has been suggested that during RF thermal ablation of biological tissue the thermal lesion could reach an equilibrium size after 1-2 minutes. Our objective was to determine under which circumstances of electrode ...
Purpose: The Cool-tip electrode is one of the most widely employed applicators in radiofrequency (RF) hepatic ablation.
Previous research demonstrated that it is possible to enlarge coagulation volume when the single ...
[EN] Although previous studies have established the feasibility of monitoring esophageal temperature during radiofrequency cardiac ablation using an esophageal temperature probe (ETP), some questions remain regarding its ...

[EN] Parabolic heat equation based on Fourier's theory (FHE), and hyperbolic heat equation (HHE), has been used to mathematically model the temperature distributions of biological tissue during thermal ablation. However, ...
[EN] Purpose
While the standard setting during radiofrequency catheter ablation (RFCA) consists of applying low power for long times, a new setting based on high power and short duration (HPSD) has recently been suggested ...
[EN] Purpose To compare the size of the coagulation (CZ) and periablational (PZ) zones created with two commercially available devices in clinical use for radiofrequency (RFA) and microwave ablation (MWA), respectively. ...
Pérez, Juan J; Berjano, Enrique; González-Suárez, Ana(MDPI AG, 2022-07-16)
[EN] Beating heart (BH) and thigh muscle (TM) are two pre-clinical models aimed at studying the lesion sizes created by radiofrequency (RF) catheters in cardiac ablation. Previous experimental results have shown that thermal ...
Berjano, Enrique; D Avila, Andre(Bentham Science, 2013)
[EN] The electrical impedance measured during radiofrequency cardiac ablation (RFCA) is widely used in clinical studies to predict the heating evolution and hence the success of the procedure. We hypothesized that a model ...
[EN] Purpose: The thermal effect of the intramyocardial blood perfusion on the size of lesions created by radiofrequency cardiac ablation (RFCA) has not been adequately studied to date. Our objective was to assess the ...
[EN] Background Proactive cooling with a novel cooling device has been shown to reduce endoscopically identified thermal injury during radiofrequency (RF) ablation for the treatment of atrial fibrillation using medium power ...
Castro-López, Dora Luz; Berjano, Enrique; Romero-Méndez, Ricardo(Springer (Biomed Central Ltd.), 2021-01-06)
[EN] Background: The volume of the coagulation zones created during radiofrequency ablation (RFA) is limited by the appearance of roll-off. Doping the tissue with conductive fluids, e.g., gold nanoparticles (AuNPs) could ...
[ES] El uso de las corrientes eléctricas de radiofrecuencia (RF) para tratar
quirúrgicamente enfermedades tan diferentes como por ejemplo el
cáncer, las alteraciones del ritmo cardiaco o la hipermetropía ocular
es relativamente ...
Purpose: The aim of this study was to compare the efficacy of bipolar (BM) vs. unipolar (UM) mode of radiofrequency ablation (RFA) in terms of creating transmural lesions across the interventricular septum (IVS) and ...
[EN] Objective: Determine whether Radiofrequency ablation (RFA) of the pancreas and
subsequent transection of the main pancreatic duct may avoid the risk of both
necrotizing pancreatitis and postoperative pancreatic ...
[EN] Background/Objective
Radiofrequency (RF) catheter ablation is a minimally invasive medical procedure used to thermally destroy the focus of cardiac arrhythmias. Novel optical techniques are now being integrated into ...
Trujillo Guillen, Macarena; Alba Martínez, José; Berjano, Enrique(Informa Healthcare, 2012-02)
Purpose: To study the relationship between roll-off (sudden increase in impedance) and spatial distribution of dehydrated tissue during RF ablation using a cooled electrode (temperatures around 100°C).
