Radiofrequency ablation could be described as a thermal strategy to destroy a tissue by increasing its temperature and causing anirreversible cellular injury. Radiofrequency ablation is a relatively new modality which has found use in a wide range of medical applications and gained acceptance. RF ablation has been used in destroying tumors in liver, prostate, breast, lung, kidney, bones, and the eye. One of the early applications in clinical setting was its use in treating supraventricular arrhythmias by selectively destroying cardiac tissue. Radiofrequency ablation has become established as the primary modality of transcatheter therapy for the treatment of symptomatic arrhythmias. Radiofrequency catheter ablation of cardiac arrhythmias were investigated using a finite-element based solution of bioheat transfer equation. Spatial and temporal temperature profiles in the cardiac tissue were visualized.

Abstract Radiofrequency catheter ablation of parahisian accessory pathways in pre-excitation syndrome is a challenging task, due to the extremely high risk of complete atrioventricular block. In this brief report we describe the case of a 32 year-old man presenting a parahisian accessory pathway, who has been successfully treated by radiofrequency ablation. Radiofrequency catheter ablation using low-power radiofrequency current is considered to be the most appropiate method of ablation in adult patients.

Premature Neonate

AbstractA 34-week premature neonate presented with drug-refractory permanent junctional incessant tachycardia and haemodynamic compromise. The patient underwent successful radiofrequency catheter ablation using a single-catheter approach. The child remains in sinus rhythm, without pharmacological treatment, 2 years after the procedure.

Methods Of Treatment

Atrial fibrillation is one of the most frequent and significant rhythm disturbances. The effectiveness and expediency of using one of the most effective methods of treatment of this arrhythmia (radiofrequency ablation in elderly patients) remains a controversial and insufficiently studied issue. The article compares the results of the treatment of 63 patients of mature age (up to 75 years) and senile age (from 75 years). Patients underwent 78 operations of radiofrequency catheter ablation of atrial fibrillation and atypical atrial flutter, which was resistant to drug therapy. In the groups of patients of mature and senile age, there were no statistically significant differences in the effectiveness of treatment. In elderly people group, a higher incidence of complications was found mainly due to hydrothorax, but these complications did not increase the risk of death and were stopped during treatment. This allows to conclude that the senile age of patients should not be the reason for refusing to conduct radiofrequency catheter ablation.
