Local ablation technologies for hepatic malignancy have developed rapidly in the past decade, with advances in several percutaneous or externally delivered treatment methods including radiofrequency ablation, microwave ablation, laser ablation, and high-intensity focused ultrasound. Research has focused on increasing the size of the ablation zone and minimizing heat-sink effects. More recent de...

We performed a survey on current atrial fibrillation (AF) ablation techniques used for catheter ablation of AF among the European Heart Rhythm Association Research Network. The focus of this questionnaire is on the ablation strategy, such as the use of different lesion sets or sites of ablation in the various forms of AF, and on the technical aspects of catheter ablation with respect to energy ...

OBJECTIVE To evaluate the economic and clinical benefits of endometrial radiofrequency ablation (RFA) compared with other ablation techniques for the treatment of menorrhagia. METHODS Using German health claims data, women meeting defined inclusion criteria for the intervention group (RFA) were selected. A comparable control group (other endometrial ablations) was established using propensity...

We report the detailed experimental study on the production of electron-spin-polarized Sr+ ions through one-photon resonant two-photon ionization via laser-excited 5s5p 3P1 (MJ = +1) of Sr atoms produced by laser-ablation. We have experimentally confirmed that the use of laser-ablation for the production of Sr atoms prior to photoionization does not affect the electron-spin polarization. We hav...

Catheter ablation is an effective treatment for atrial fibrillation (AF). However, over long-term follow-up, it is becoming clear that AF often recurs and repeat ablation is required. With the goal of improving efficacy, particularly in those patients with risk factors for poor outcomes using a standard endocardial ablation technique, surgical epicardial ablation has emerged as an alternative m...

OBJECTIVE To evaluate the cost difference between a daycase endometrial thermal ablation performed under general anaesthesia and an outpatient endometrial ablation using local anaesthetic. STUDY DESIGN Calculations using real reported resource use in 20 daycase procedures and 16 outpatient procedures. RESULTS The costs were 1865 euros for daycase procedure versus 1065 euros for outpatient p...

In order to compare the clinical efficacy, safety, success rate and probable complications of rollerball ablation with cutting loop endometrial resection in the treatment of menorrhagia, eighty-three women in reproductive age suffering from menorrhagia who did not respond to medication were treated in a randomized study comparing cutting loop endometrial resection with hysteroscopic rollerb...
