This case report describes radiofrequency pulmonary vein isolation in a 67-year-old man with dextrocardia and situs inversus totalis. The procedure successfully isolated all pulmonary veins using 3D mapping with intracardiac echocardiography guidance. No procedural complications were reported, and the authors…

This pre/post study measured circulating microRNA profiles in 30 atrial fibrillation patients before and 3 months after radiofrequency ablation, comparing results with 10 healthy controls. The authors report that numerous miRNAs differed from controls at baseline and shifted after ablation, with several highlighted…

This study evaluated whether fusing delayed enhancement MRI (DE-MRI) with magnetic resonance angiography (MRA) improves visualization of radiofrequency ablation lesions after pulmonary vein isolation. Eighteen atrial fibrillation ablation patients underwent both imaging approaches, and two observers scored lesion…

This retrospective study evaluated liver lesion conspicuity during real-time MR-guided radiofrequency applicator placement using spoiled GRE and balanced SSFP MRI sequences in a 1.5 T scanner. Lesion detectability categories and contrast-to-noise ratio (CNR) were compared for hepatocellular carcinoma and liver…

This observational study followed 36 patients for 2 years after temperature-controlled radiofrequency tissue volume reduction for turbinate hypertrophy. Patients reported significantly lower VAS symptom scores (nasal obstruction, headache, rhinorrhoea, anosmia) after treatment compared with baseline. Urban residence…

This experimental animal study evaluated whether a radiofrequency method could induce thrombosis within an abdominal aortic aneurysm sac to potentially prevent endoleaks after endovascular repair. Six dogs received radiofrequency blood clotting of the sac and then stent-grafting, compared with a historical group of…

This article describes a surgical technique for arthroscopic capsular release in adhesive capsulitis using a flexible hip arthroscopy radiofrequency ablator. The authors present it as a creative approach intended to improve safety and precision in a procedure that can be technically challenging. The abstract does not…

This experimental and clinical study compared two umbrella-shaped expandable radiofrequency ablation electrodes (SuperSlim vs CoAccess) across different ablation algorithms. In ex vivo bovine liver, CoAccess generally produced larger ablation areas and required longer ablation times than SuperSlim, with no…

This case report describes a 60-year-old man with a dual-chamber implantable cardioverter defibrillator who underwent septal myectomy and a right atrial radiofrequency maze procedure. Following surgery, a persistent delay in atrial sensing was observed. The authors attribute this most likely to iatrogenic right…

This monocentric study evaluated outpatient feasibility and outcomes of radiofrequency transurethral needle ablation (TUNA) for benign prostatic hyperplasia in patients who did not respond to medical therapy. In the outpatient subgroup, urinary symptom scores, quality of life, flow measures, and residual urine…

This clinical report describes the use of radiofrequency (RF) technology in surgery of abdominal and thoracic parenchymatous organs in 17 patients. The authors report one complication (pleural effusion) and otherwise no additional organ complications in the abstract. They also describe a case of splenic preservation…

This clinical study reports outcomes for 34 patients with mild and median OSAHS treated with a combination of functional endoscopic sinus surgery, UPPP, and radiofrequency ablation (RFA). Over 1 year, polysomnography showed a reduction in AHI and an effective rate of 85.29%. Because RFA was used as an adjunct to…

This animal study evaluated two multiprobe radiofrequency ablation device approaches in pigs, including an impedance-based algorithm and clustered/combination probes with and without a switcher controller. The Pringle maneuver was associated with larger ablation volumes and shorter ablation times in one experiment,…
