Sluijter et al.8 assumed that, because the tissue temperature was kept below the thermal destructive range, thermal tissue injury was avoided. By using mathematical calculations, they further showed that the high-density electrical currents generated at the electrode tip stressed the cellular membranes and biomolecules and caused altered cell function, leading to cell injury. Later investigator...

Despite advances in ablation technology, many patients experience recurrent atrial fibrillation (AF) after radiofrequency ablation. Although estimates vary, the overall 1-year drug-free success for AF ablation is estimated at 40% to 60% for a single procedure and 70% for multiple procedures. The cornerstone of conventional AF ablation is pulmonary vein isolation (PVI), and in clinical practice,...

We studied the effect of noninvasive radiofrequency-induced hyperthermia on the viability of Aspergillus fumigatus hyphae in vitro. Radiofrequency-induced hyperthermia resulted in significant (>70%, P < 0.0001) hyphal damage in a time and thermal dose-dependent fashion as assessed by XTT [(sodium 2,3,-bis(2-methoxy-4-nitro-5-sulfophenyl)-5-[(phenylamino)-carbonyl] (1)-2H-tetrazolium inner salt)...

Background Previous reports have shown that radiofrequency ablation can terminate atrial flutter and prevent recurrences. However, different methods have been used, and the current experience remains limited. The objective of the present study was to determine the efficacy of radiofrequency ablation of atrial tissue in patients with atrial flutter using an anatomically guided approach. Methods ...

INTRODUCTION Hand-assisted laparoscopic liver surgery, a newly developed technique based on an innovative concept, has proved useful and safe for a variety of less invasive hepatectomies. Radiofrequency-assisted hepatic resection has been reported to be safe, associated with minimal morbidity and mortality and decreased intraoperative blood loss and transfusion requirements. AIM We describe h...

conclusions the mode of action of prf is far from being completely elucidated. the high frequency current induces an electric field that in turn seems to influence the immunity, the inflammation and other pain conducting mechanisms. our findings suggest an effect distal from the application of the current. it reaches targets that are difficultly attainable by any other means of current applicat...

background: after radiofrequency catheter ablation of arrhythmias, patients have to bed rest for 4-6 h to prevent bleeding and hematoma. however, such a rest may cause back pain in the patients. the aim of this study was to determine the effects of continuous change in body position during and after the radiofrequency ablation on the back pain. materials and methods: in a quasi‑experimental des...

Background and aim: Skin rejuvenation is in demand. In recent years, mono- and bipolar radiofrequency (RF) have been reckoned as treatment of choice for this purpose. The studies on RF have shown the remodeling of collagen fibers and consequently improvement of skin texture although risks and side effects may exist.Methods: Forty-eight patients requesting skin rejuvenation were treated by RF af...
