REVIEW
Steven P Cohen, W Michael Hooten
Neck pain imposes a considerable personal and socioeconomic burden-it is one of the top five chronic pain conditions in terms of prevalence and years lost to disability-yet it receives a fraction of the research funding given to low back pain. Although most acute episodes resolve spontaneously, more than a third of affected people still have low grade symptoms or recurrences more than one year later, with genetics and psychosocial factors being risk factors for persistence. Nearly half of people with chronic neck pain have mixed neuropathic-nociceptive symptoms or predominantly neuropathic symptoms...

Electrical storm (ES) is not a rare clinical entity. Sympathetic hyperactivity may play critical role in development and continuation of ES. Some recent reports have demonstrated that catheter-based renal sympathetic denervation (RSD) may reduce sympathetic activation and have a potential role in reducing arrhythmic burden. A 46-year-old man was admitted to clinic with frequent implantable cardioverter defibrillator shocks and ES related to catecholaminergic polymorphic ventricular tachycardia (VT). Tachycardia was unresponsive to administration of beta-blockers, verapamil, and flecainide...

Background: Loin pain haematuria syndrome (LPHS) and autosomal dominant polycystic kidney disease (ADPKD) are the most important non-urological conditions to cause chronic severe kidney-related pain. Multidisciplinary programmes and surgical methods have shown inconsistent results with respect to pain reduction. Percutaneous catheter-based renal denervation (RDN) could be a less invasive treatment option for these patients. Methods: Our aim was to explore the change in perceived pain and use of analgesic medication from baseline to 3, 6 and 12 months after RDN...

Implantable cardioverter-defibrillator (ICD) is the gold standard therapy for the prevention of sudden cardiac death. Nevertheless, ICD placement in the paediatric population is still limited because of several technical difficulties. Several implantation techniques have been proposed but experience in infants with very low weight and less than 6 months is very limited. We herein describe a case of a minimally invasive ICD epicardial implantation in a 4-month-old infant weighing 5 kg. A diagnosis of arrhythmic cardiomyopathy with left ventricular non-compaction disease with ventricular tachycardia storms, QT prolongation and Wolff-Parkinson-White pattern was made...

OBJECTIVE: Renal denervation (RDN) can cause focal (notches) and global (spasms) changes in renal artery dimensions. We quantified these changes and related them to renal norepinephrin tissue content in animals and to blood pressure (BP) changes in patients. METHODS: We measured renal artery dimensions pre-RDN and post-RDN, utilizing quantitative renal angiography (QRA) in a porcine model and in a retrospective patient cohort, and intravascular ultrasound (IVUS) in a prospective patient cohort...

BACKGROUND: Catheter-based renal denervation (RDN) is a promising approach to treat hypertension, but innervation patterns limit the response to endovascular RDN and the post-procedural renal artery narrowing or stenosis questions the endovascular ablation strategy. This study was performed to investigate the anti-hypertensive and target organ protective effects of perivascular RDN in spontaneously hypertensive rats (SHR). METHODS: SHR and normotensive Wistar-Kyoto (WKY) rats were divided into sham group (n = 10), radiofrequency ablation group (n = 20) in which rats received bilateral perivascular ablation with radiofrequency energy (2 watts), and chemical (10% phenol in 95% ethanol) ablation group (n = 12)...

INTRODUCTION: The effectiveness of renal sympathetic denervation (RDN) as a treatment for therapy-resistant hypertension has been doubted as the Simplicity-HTN-3 trial was unable to show any treatment benefit over sham procedure. This might partly be explained by a high procedural variability in treatment with radiofrequency-based catheters. Recently, newer systems for RDN, like ultrasound-based devices, have been introduced into practice. To date however, data on their effectiveness for the treatment of resistant hypertension are scarce...

OBJECTIVES: Renal sympathetic denervation has been studied as a potential therapeutic option for patients with therapy-resistant hypertension; however, a significant proportion of patients do not show a significant reduction in blood pressure and are classified as non-responders. The objective of the present study was to assess whether a redo renal denervation procedure increases response rates. METHODS: We present a case series of three consecutive renal denervation non-responders treated with the multi-electrode radiofrequency St...
