Background. Radiofrequency energy has been used safely and successfully to eliminate accessory pathways in patients with the Wolff-Parkinson-White syndrome and the substrate for atrioventricular nodal reentrant tachycardia. However, this form of ablation has had only limited success in eliminating ventricular tachycardia in patients with structural heart disease. In contrast, direct-current cat...
AIM The occurrence of accelerated junctional rhythm during radiofrequency energy delivery at the region of the slow pathway is a well-recognized marker of successful treatment of atrioventricular nodal re-entry tachycardia (AVNRT). Our aim was to evaluate if the quantity and duration of accelerated junctional rhythm during radiofrequency ablation of the slow pathway is correlated with residual ...
BACKGROUND Therapeutic management of asymptomatic patients with a Wolff-Parkinson-White (WPW) pattern is controversial. We compared the risk:benefit ratios between prophylactic radiofrequency ablation and no treatment in asymptomatic patients with WPW. METHODS AND RESULTS Decision analysis software was used to construct a risk-benefit decision tree. The target population consisted of 20- to 4...
PURPOSE To evaluate the usefulness and safety of radiofrequency ablation for primary and recurrent intrahepatic cholangiocarcinoma (ICC) in our single centre experience. MATERIALS AND METHODS Ten patients with ICC refusing or not eligible for surgery underwent radiofrequency ablation for their tumor. The ICC was primary in 9 cases and recurrent, after 2 previous resections, in 1 patient. Radi...
In the last few years, radiofrequency ablation has become one of the most promising techniques to treat liver tumors. But radiologists have to face the difficulty of planning their treatment while only relying on 2D slices. We present here a realistic radiofrequency ablation simulation tool, coupled with a 3D reconstruction and visualization project. They help radiologists to have a better visu...
Thermal ablation using radiofrequency is a new, minimally invasive modality employed as an alternative to surgery in patients with benign thyroid nodules and recurrent thyroid cancers. The Task Force Committee of the Korean Society of Thyroid Radiology has developed recommendations for the optimal use of radiofrequency ablation for thyroid nodules. These recommendations are based on a comprehen...
A 36 year-old man with Wolff Parkinson White syndrome due to a left-sided accessory pathway (AP) was referred for catheter ablation. Whether abolition of antegrade and retrograde AP conduction during ablation therapy occurs simultaneously, is unclear. At the ablation procedure, radiofrequency delivery resulted in loss of preexcitation followed by a short run of orthodromic tachycardia with ecce...
BACKGROUND Radiofrequency catheter ablation for paroxysmal atrial fibrillation is well established but not drawback free. Pulmonary vein stenosis is one of the complications and usually treated with stenting with the disadvantages of high re-stenosis rate and anticoagulant dependence. CASE PRESENTATION Herein, we present the case of a 47 year-old lady, who suffered from fever and hemoptysis d...
Background The feasibility and efficacy of radiofrequency ablation therapy in idiopathic left ventricular tachycardia has not been assessed in a large group of patients. Methods and Results Twenty consecutive patients with idiopathic left ventricular tachycardia and without structural heart disease underwent electrophysiological study, pharmacological interventions with administration of verapa...
