Radiofrequency cardiac ablation with catheters placed on opposing sides of the ventricular wall: Computer modelling comparing bipolar and unipolar modes

González Suárez, Ana; Trujillo Guillen, Macarena; Koruth, Jacob; d'Avila, Andre; Berjano, Enrique (Informa Healthcare, 2014-09)

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 ...
Radiofrequency pancreatic ablation and section of the main pancreatic duct does not lead to necrotizing pancreatitis

Quesada, Rita; Burdío, Fernando; Iglesias, Mar; Dorcaratto, Dimitri; Cáceres, Marta; Andaluz, Anna; Poves, Ignasi; Castiella, Tomás; Sánchez, Patricia; Berjano Zanón, Enrique; Grande, Luís (Lippincott, Williams &amp; Wilkins, 2014-08)

[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 ...
Relation between Denaturation Time Measured by Optical Coherence Reflectometry and Thermal Lesion Depth during Radiofrequency Cardiac Ablation: Feasibility Numerical Study

González-Suárez, Ana; Herranz, David; Berjano, Enrique; Rubio-Guivernau, Jose L.; Margallo-Balbás, Eduardo (John Wiley & Sons, 2018)

[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 ...
Relationship between roll-off occurrence and spatial distribution of dehydrated tissue during RF ablation with cooled electrodes

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). Methods: We used ...
Reliability assessment of a cooled intraesophageal balloon to prevent thermal injury during RF cardiac ablation: an agar phantom study.

Lequerica, Juan L.; Berjano, Enrique; Herrero, Maria; Hornero, Fernando (Blackwell Publishing, 2008)

[EN] Cooled Balloon Prevents Thermal Injury During RF Ablation. Introduction: The use of a cooled intraesophageal balloon has recently been proposed to minimize the risk of thermal injury in the esophagus during radiofrequency ...
Review of the mathematical functions used to model the temperature dependence of electrical and thermal conductivities of biological tissue in radiofrequency ablation.

Trujillo Guillen, Macarena; Berjano, Enrique (Informa Healthcare, 2013-09)

Purpose: Although theoretical modelling is widely used to study different aspects of radiofrequency ablation (RFA), its utility is directly related to its realism. An important factor in this realism is the use of mathematical ...
Should fluid dynamics be included in computer models of RF cardiac ablation by irrigated-tip electrodes?

González Suárez, Ana; Pérez, Juan J; Berjano, Enrique (Springer (Biomed Central Ltd.), 2018)

[EN] Background: Although accurate modeling of the thermal performance of irrigated-tip electrodes in radiofrequency cardiac ablation requires the solution of a triple coupled problem involving simultaneous electrical ...
