Direct measurement of the lethal isotherm for radiofrequency ablation of myocardial tissue.
BACKGROUND The lethal isotherm for radiofrequency catheter ablation of cardiac myocardium is widely accepted to be 50°C, but this has not been directly measured. The purpose of this study was to directly measure the tissue temperature at the edge of radiofrequency lesions in real time using infrared thermal imaging. METHODS AND RESULTS Fifteen radiofrequency lesions of 6 to 240 seconds in dur...
متن کاملAn Investigation of Brightness Changes in Ultrasound Images due to Temperature Variations in Liver Tissue during Radiofrequency Ablation
Introduction: one of the minimally invasive methods of treatmenting liver malignancies is Radiofrequency Ablation (RFA) which can be applied to primary or secondary tumors. Nevertheless, the disease recurrence is probable after RFA application partially due to the inadequate capability of temperature monitoring of the target tissue and visualizing the thermal damage. The goal of this work was t...
متن کاملRelative brightness due to temperature changes with ultrasound image analysis during Radiofrequency ablation
Introduction: Diagnosis of primary and secondary cancers to treat patients with diffuse and malignant tumors is an important subject. The appropriate treatment will be eliminating primary and metastatic tumors. Radiofrequency ablation with localized heat induction in the target tissue causes irreversible cellular damage and tissue coagulation. Estimation of tissue temperature c...
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 کاملMicrowave catheter ablation of myocardium in vitro. Assessment of the characteristics of tissue heating and injury.
BACKGROUND Radiofrequency (RF) catheter ablation lesion size has been limited by the small volume of tissue directly heated by the RF electrode. Microwave (MW) energy has been proposed as an alternative energy source to generate larger lesions because of its increased volume of direct tissue heating. To further characterize MW ablation of myocardium, we studied the temperature-versus-distance p...
