Atrial fibrillation and its determinants after radiofrequency ablation of chronic common atrial flutter
atrial fibrillation atrial flutter follow-up radiofrequency catheter ablation
2015/7/29
Aim. Atrial fibrillation (AFib) is a major clinical issue and its occurrence is the main problem after catheter ablation of atrial flutter. The long-term occurrence of AFib after common atrial flutter...
Radiofrequency Ablation of Liver Tumors: The First Preliminary Report in Iran
radiofrequency catheter ablation liver tumors
2010/2/1
Background/Objective: Radiofrequency ablation (RFA) is emerging as a new therapeutic technique for unresectable hepatic malignancies. We report our experience with the use of this method for the first...

radiofrequency ablation state-of-the-art and challenges the future
2010/2/26
Radiofrequency ablation is an interventional technique that in recent years has come to be employed in very different medical fields, such as the elimination of cardiac arrhythmias or the destruction ...
Automatic control of finite element models for temperature-controlled radiofrequency ablation
finite element models temperature-controlled radiofrequency ablation
2010/2/26
We present results of a temperature controlled 3-D FEM model of a RITA model 30 electrode. The control software effectively controlled applied voltage in the FEM model to obtain, and keep electrodes a...
Thermal modeling of lesion growth with radiofrequency ablation devices
Thermal modeling of lesion growth radiofrequency ablation devices
2010/3/1
The data demonstrate the size of thermal lesions is grossly overestimated when calculated using traditional temperature isocontours of 42°C and 47°C. The computational model results predicted lesion d...
Finite Element Analysis of Hepatic Radiofrequency Ablation Probes using Temperature-Dependent Electrical Conductivity
Hepatic Radiofrequency Ablation Temperature-Dependent Electrical Conductivity
2010/3/1
The data demonstrate that significant errors are generated when constant electrical conductivity is assumed in coupled electrical-heat transfer problems that operate at high temperatures. These errors...
