BACKGROUND: Verapamil-sensitive idiopathic left ventricular tachycardia (verapamil-ILVT) is thought to be due to a reentry within the LV fascicular system. Radiofrequency catheter ablation (RFCA) is effective for elimination of the VT; however, a long-term prognosis of patients with verapamil-ILVT is still unclear. METHODS AND RESULTS: Eighty consecutive verapamil-ILVT patients (62 men, 31±12 years-of-age, LVEF: 65±4%) were enrolled. Seventy-six (95%) cases of VT involved right bundle brunch block and left axis deviation...

A 51-year-old male patient presented with frequent and symptomatic premature ventricular complexes (PVCs) that had induced cardiomyopathy. Radiofrequency (RF) catheter ablation of the origin of the PVCs was planned and the patient underwent electrophysiological study. During activation mapping, the earliest ventricular activation was identified at the His bundle region. Small His bundle electrogram recording by the distal ablation electrode during sinus rhythm revealed that the earliest ventricular activation during PVC preceded the QRS onset by 58 milliseconds...

The development of fractional photothermolysis has revolutionized the treatment of skin scarring, rejuvenation, and tightening. By creating targeted microthermal zones and leaving surrounding tissue intact, this concept has provided the field with efficacious results, with less downtime and a better safety profile. This has started to change the paradigm of what is considered first-line treatment for scarring and rejuvenation. While originally applied to nonablative lasers, fractionation has now been employed in ablative, quality-switched, picosecond, and novel hybrid fractional lasers...

In spite of recent improvements in both the technical delivery of radiotherapy and systemic therapy in the treatment of non-small cell lung cancer, local recurrence rates after radiotherapy remain a significant challenge. In the setting of local relapse after radiotherapy, treatments such as surgical resection or radiofrequency ablation are often not appropriate owing to disease and patient factors. Re-irradiation may be a potential treatment option. This overview considers the published evidence and potential treatment strategies...

BACKGROUND: Pulmonary vein isolation is the cornerstone of ablation for persistent atrial fibrillation (AF). The role of balloon catheters in this patient population remains ill defined. We sought to compare efficacy and safety of the laser balloon (LB) with wide-area circumferential pulmonary vein isolation using irrigated radiofrequency current (RF) ablation and 3-dimensional mapping. METHODS AND RESULTS: In 6 European centers, patients with persistent AF were prospectively randomized...

The current standard of treating early Barrett's neoplasia is resection of visible lesions using endoscopic mucosal resection (EMR) followed by ablative therapy to the Barrett's segment. There is increasing evidence to support the use of endoscopic submucosal dissection (ESD) where en-bloc resection and lower recurrence rates may be achieved. However, ESD is associated with deep submucosal dissection when compared to EMR. This may increase the risk of complications including stricture formation with subsequent radiofrequency ablation (RFA) therapy...

BACKGROUND: To achieve sinus rhythm, ablation of long-standing persistent atrial fibrillation (LSPAF) usually requires substrate modification in addition to pulmonary vein isolation (PVI). In the present article, we aimed to compare clinical and substrate modification effects of 2 distinct PVI strategies during stepwise ablation in patients with LSPAF: (1) Combined approach: cryoballoon (CB) for PVI and radiofrequency (RF) ablation for substrate modification and (2) RF-only approach: RF ablation for both PVI and substrate modification...

Pancreatic neuroendocrine tumors (PNETs) are increasingly being detected, though usually as incidental findings. Majority of the PNETs are non-functional and surgical resection is the standard of care for most of them. However, in patients with small PNETs localized within the pancreas, who are unfit or unwilling for surgery, alternate methods of treatment are needed. Direct methods of ablation of PNETs, using either ethanol injection or radiofrequency ablation (RFA), are emerging as effective methods. The limited literature available as case reports or case series on endoscopic ultrasound (EUS)-guided local ablation using either ethanol or RFA has demonstrated safety and efficacy along with short- to medium-term sustained relief...

OBJECTIVES: High-resolution ultrasonography (US) can play an important role in studying nerves, as it has several advantages. Entrapments of distal tibial nerve branches can be mapped out or diagnosed with selective anesthetic blocks, and US can guide therapeutic procedures, such as radiofrequency ablation and selective infiltrations of specific nerve branches. The aim of this study was to verify that US is an effective method for accurately locating the posterior tibial nerve and its terminal branches, such as the medial calcaneal branch, the first calcaneal branch, and the medial and lateral plantar nerves...

Objectives: Palmar hyperhidrosis (PH) exhibits excessive and unpredictable sweating. The most effective treatment for permanent cure is the ablation of thoracic sympathetic ganglia innervating hands. However, sympathectomy of T2 sympathetic ganglion by clipping or cauterization causes irreversible nerve damage, and results in a compensatory hyperhidrosis (CH). We herein used the pulsed radiofrequency (PRF) stimulation to reversibly block sympathetic ganglion to treat PH and avoid CH. Material and Methods: A bipolar electrode was implanted into the right T2 sympathetic trunk by endoscopic surgery and PRF was delivered through the electrode...
