Tissue heating during tumor ablation with irreversible electroporation
Exposing biological cells to sufficiently strong external electric fields causes electroporation of cell membranes, i.e. occurrence of transient or permanent permeable pathways between the interior and exterior of the cell. Electroporation can be used to introduce various molecules into cells (reversible electroporation) or to kill cells (irreversible electroporation), which can in turn be used...
متن کاملNoninvasive assessment of tissue heating during cardiac radiofrequency ablation using MRI thermography.
BACKGROUND Failure to achieve properly localized, permanent tissue destruction is a common cause of arrhythmia recurrence after cardiac ablation. Current methods of assessing lesion size and location during cardiac radiofrequency ablation are unreliable or not suited for repeated assessment during the procedure. MRI thermography could be used to delineate permanent ablation lesions because tiss...
متن کاملI-46: Radiofrequency Ablation of Uterine Fibroids
Uterine fibroids are benign solid tumors that are present in the majority of women. While often asymptomatic, fibroids can result in abnormal uterine bleeding, pelvic pressure, pain, subfertility, dyspareunia and other symptoms. Submucous and intramural fibroids are most associated with heavy menstrual bleeding; subserosal fibroids are more often innocuous unless sufficiently large so as to con...
متن کاملImpedance During Radiofrequency Ablation of Ventricular Myocardium
The purpose of this study was to correlate changes in electrical impedance with the electrode-tissue interface temperature and to characterize the associated events occurring at the catheter tip electrode. In a canine model, lesions were created in vitro (n =49) and in vivo (n =31) and radiofrequency power settings were varied. Electrode-tissue interface temperature, delivered current, and volt...
متن کاملSequential Anterograde and Retrograde Conduction Block during Radiofrequency Ablation of an Accessory Pathway
We present an interesting image showing sequential loss of anterograde, and subsequently, retrograde conduction during radiofrequency ablation of an accessory pathway. We discuss the possible mechanisms and prior literature concerning this interesting finding.
