Frequent ventricular premature complexes (VPC) can result in left ventricular dysfunction. Several case reports have found this association and reversal with radiofrequency ablation [1-4]. Other peculiar problems reported to be due to VPCs and relieved by radiofrequency ablation include intermittent claudication [5], chronic cough with cough syncope [6,7] and dysphagia [8], mostly by the same g...

Aims Atrial fibrillation represents a frequent and potentially life-threatening arrhythmia in patients with accessory atrioventricular pathways. Radiofrequency ablation has become the curative treatment of first choice for these patients. Investigations after successful surgical pathway dissection reported an almost complete elimination of paroxysmal atrial fibrillation. However, there are only...

Synopsis The current MRI safety standards for exposure to radiofrequency �elds are conservative and intended to protect the entire patient population. Limits set on whole-body average speci�c absorption rate take the patient’s weight into consideration, which allows robust, but only very rudimentary patientspeci�c exposure estimation. The introduction of combined morphing and posing in compu...

Radiofrequency ablation has an important role in the management of post infarction ventricular tachycardia. The mapping and ablation of ventricular tachycardia (VT) is complex and technically challenging. In the era of implantable cardioverter defibrillators, the role of radiofrequency ablation is most commonly reserved as an adjunctive treatment for patients with frequent, symptomatic episodes...

Introduction. Congenital nasopharyngeal teratomas are rare tumours that pose difficulties in diagnosis and surgical management. We report the first use of radiofrequency coblation in the management of such tumours. Case Report. A premature baby with a perinatal diagnosis of a large, obstructing nasooropharyngeal mass was referred to the ENT service for further investigations and management. The...

In the last decade, Radiofrequency (RF) energy has proven to be safe and highly efficacious for face and neck skin tightening, body contouring, and cellulite reduction. In contrast to first-generation Monopolar/Bipolar and "X -Polar" RF systems which use one RF generator connected to one or more skin electrodes, multisource radiofrequency devices use six independent RF generators allowing effic...

BACKGROUND Many patients with chronic tendinosis have experienced early pain relief after application of bipolar radiofrequency treatment. It is hypothesized that the mechanism of action may be the acute degeneration and/or ablation of sensory nerve fibers. HYPOTHESIS After ablation or degeneration by bipolar radiofrequency, nerve fibers will have the ability to regenerate with time. STUDY ...

BACKGROUND Minimally invasive surgeries of the soft palate have emerged as a less-invasive treatment for habitual snoring. To date, there is only limited information available comparing the effects of snoring sound between different minimally invasive surgeries in the treatment of habitual snoring. OBJECTIVE To compare the efficacy of palatal implant and radiofrequency surgery, in the reducti...

Radiofrequency switches are critical components in wireless communication systems and consumer electronics. Emerging devices include switches based on microelectromechanical systems and phase-change materials. However, these devices suffer from disadvantages such as large physical dimensions and high actuation voltages. Here we propose and demonstrate a nanoscale radiofrequency switch based on ...

CONTEXT There is little reported experience of radiofrequency ablation of pancreatic tumours. Our group has reported the development of a porcine pancreatic model of radiofrequency ablation of the pancreas. This brief report details the application of this technique to clinical practice. CASE REPORT A 58-year-old man with metastatic pancreatic tumour underwent operative radiofrequency ablatio...
