BACKGROUND Imaging of myocardial ablation lesions during electrophysiology procedures would enable superior guidance of interventions and immediate identification of potential complications. The aim of this study was to establish clinically suitable MRI-based imaging techniques for intraprocedural lesion visualization in interventional electrophysiology. METHODS AND RESULTS Interventional ele...

BACKGROUND Ventricular tachycardia (VT) refractory to antiarrhythmic drugs and standard percutaneous catheter ablation techniques portends a poor prognosis. We characterized the reasons for ablation failure and describe alternative interventional procedures in this high-risk group. METHODS AND RESULTS Sixty-seven patients with VT refractory to 4±2 antiarrhythmic drugs and 2±1 previous endocar...

Image-guided tumor ablation for lung malignancies has emerged as a treatment modality for medically inoperable patients. Overall, image-guided lung tumor ablation is a minimally invasive procedure that has an acceptable safety profile and less impact on lung function. This is important for patients with poor pulmonary and/or cardiac functions or with multiple comorbidities, which prevent them f...

OBJECTIVE We evaluated Novasure ablation as a mechanical endometrial preparation agent before Roller Ball endometrial ablation in lieu of GnRH agonists in large uteri. METHODS A retrospective chart review of 20 consecutive patients undergoing Novasure ablation for mechanical endometrial preparation before Roller Ball ablation (RBNovasure group) was conducted and the results compared to that o...

INTRODUCTION LocaLisa is a novel system for anatomical mapping. It enables an assessment of the three-dimensional position of electrodes within cardiac chambers without fluoroscopy. With this technique it may be possible to reduce radiation exposure during catheter-based ablation procedures. AIM To evaluate the efficacy and safety of ablation procedures performed using the LocaLisa mapping sy...

Objective To assess the efficacy and safety of thyroid radiofrequency (RF) ablation for benign thyroid nodules by trained radiologists according to a unified protocol in a multi-center study. Materials and Methods From 2010 to 2011, 345 nodules from 345 patients (M:F = 43:302; mean age ± SD = 46.0 ± 12.7 years, range = 15-79) who met eligibility criteria were enrolled from five institutions. ...

OBJECTIVE To compare physician assessment of the next-generation NovaSure(®) device to the original NovaSure device. DESIGN Prospective open-label, unblinded survey utilizing Likert scales. SETTING Community-based obstetrician and gynecology practices. PATIENTS There were 270 evaluations completed by 168 physicians for women undergoing endometrial ablation with the next-generation NovaSur...

We develop and characterize a UV ablation technique that can be used to pattern soft materials such as polymers and nonlinear molecules self-assembled over silica microstructures. Using this method, we fabricate a spatially periodic coating of nonlinear film over a thin silica fiber taper for second harmonic generation (SHG). Experimentally, we find that the second harmonic signal produced by t...
