BACKGROUND Epicardial radiofrequency catheter ablation of ventricular tachycardia remains challenging because of the presence of deep myocardial scar and adjacent cardiac structures, such as the coronary arteries, phrenic nerve, and epicardial fat that limit delivery of radiofrequency energy. High-intensity ultrasound (HIU) is an acoustic energy source able to deliver deep lesions through fat, ...

OBJECTIVE To compare the outcomes of the nasal obstruction, the main symptom of the patients who underwent radiofrequency and lateral displacement of the inferior turbinate and patients who were treated with radiofrequency alone. METHODS The prospective randomised study was conducted at the Department of Otorhinolaryngology and Head-Neck Surgery, Balikesir University Medical School, Balikesir...

PURPOSE To investigate the inhibitory effect of 0.02% mitomycin C on eyelash regrowth when injected to the eyelash hair follicle immediately after radiofrequency ablation. METHODS We prospectively included 21 trichiasis patients from June 2011 to October 2012. Twenty eyes of 14 patients were treated with 0.02% mitomycin C to the hair follicle immediately after radiofrequency ablation in group...

PURPOSE To verify the topographical alterations in enucleated pig eye cornea after radiofrequency application. METHODS A prototype radiofrequency modulator with 10 different energy possibilities was used. For each energy we used 10 enucleated pig eyes that were topographed before and after applying radiofrequency, following a nomogram with 8 spots in step one, 16 spots in step 2, and 24 spots...

This report describes a case of bilateral greater occipital neuralgia treated with cooled radiofrequency ablation. The case is considered in relation to a review of greater occipital neuralgia, continuous thermal and pulsed radiofrequency ablation, and current medical literature on cooled radiofrequency ablation. In this case, a 35-year-old female with a 2.5-year history of chronic suboccipital...

OBJECTIVE To establish whether SkBF can be modified by exposure to the radiofrequency waves emitted by a mobile phone when the latter is held against the jaw and ear. METHODS Variations in SkBF and Tsk in adult volunteers were simultaneously recorded with a thermostatic laser Doppler system during a 20-minute "radiofrequency" exposure session and a 20-minute "sham" session. The skin microvess...

Sixteen patients with type I atrial flutter underwent an attempt at radiofrequency catheter ablation (8 women, 8 men, mean age 53 +/- 11 years). The primary criterion used to identify sites for radiofrequency energy delivery was the identification of a fractionated electrogram. Radiofrequency energy was delivered for 20 to 30 seconds. Radiofrequency catheter ablation was acutely successful in 1...

On this anniversary issue, I wanted to congratulate you and thank you for making the Journal of Atrial Fibrillation (JAFIB) a great success. With specific focus on atrial fibrillation we have been able to surpass our targets thanks to your active participation and support. With the continued progress made in the field of diagnostic and therapeutic tools for treating AF, this past year has witne...

The problem of targeted delivery and controlled release of a chemical payload in difficult-toaccess microstructured environments such as living tissues or porous soil is considered. Composite microcapsules consisting of the thermo-responsive hydrogel poly-Nisopropylacrylamide (PNIPAM) with dispersed iron oxide nanoparticles have been prepared by w/o emulsion polymerization. The microcapsules ar...
