OBJECTIVE Currently radiofrequency and cryoballoon ablations are the two standard ablation systems used for catheter ablation of atrial fibrillation; however, there is no universal consensus on which ablation is the optimal choice. We therefore sought to undertake a meta-analysis with special emphases on comparing the efficacy and safety between cryoballoon and radiofrequency ablations by synth...

We describe a case of radiofrequency ablation of ventricular premature contraction (VPC) originating from the left ventricular outflow tract after transcatheter aortic valve replacement. The VPC origin was the native aortic valve annulus between the left and right coronary cusps. Radiofrequency ablation was successfully performed by manipulating the ablation catheter from the gap between the si...

PURPOSE To investigate the efficiency of partial radiofrequency ablation of the spleen in patients with thalassemia major and intermedia. MATERIALS AND METHODS Partial radiofrequency ablation of the spleen was performed in 19 thalassemic patients (10 females, nine males) with a mean age of 12.7 years (age range, 7-30 years). This group of patients consisted of 11 patients with thalassemia maj...

The results of radiofrequency catheter ablation of ventricular tachycardia (VT) in patients without structural heart disease are reported. Particular attention was focused on the relation between efficacy and the site of origin of the VT. Eighteen consecutive patients (5 women and 13 men; mean age 41 +/- 13 years) with idiopathic VT underwent catheter ablation using radiofrequency energy. Sites...

Background: Local ablative treatments play an important role for patients who cannot be treated surgically. Radiofrequency ablation is a well-established alternative to surgical treatment of thyroid nodules, however it also has disadvantages. Microwave ablation (MWA) is a new minimally invasive treatment promising several improvements. The aim of this retrospective study was to evaluate the eff...

Chronic tonsillitis is a common disease, and several different surgical techniques are used to treat this condition. In recent years, techniques such as radiofrequency ablation and coblation have been commonly used for tonsil surgery. In this report, we present the cases of two pediatric patients who developed ptosis, miosis, and enophthalmos (Horner syndrome) after radiofrequency ablation for ...

OBJECTIVES To describe the various techniques that have been developed for application of radiofrequency ablation in the palliative treatment of recurrent and advanced head and neck malignant tumors. DESIGN Case series with a follow-up of 3 to 18 months. SETTING Faculty practice, research protocol, tertiary care academic medical center. PATIENTS Fifteen treatments were administered over a...

OBJECTIVE To evaluate the results of intraoperative radiofrequency ablation with biatrial procedure in the treatment of chronic atrial fibrillation in patients with associated cardiac disease. METHODS Between February 2008 and May 2009, 15 consecutive patients were underwent mitral valve procedure plus modified radiofrequency biatrial ablation of chronic atrial fibrillation. The mean age was ...

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...
