Isolated coronary artery bypass grafting associated with atrial fibrillation is routinely performed through a sternotomy, and cardiac arrest. Advancements in this surgical approach have led to better cosmesis, a quick postoperative recovery, with the same postoperative results. We report a case of a novel, less invasive hybrid treatment combining robot-assisted coronary artery bypass grafting and percutaneous radiofrequency catheter ablation.

OBJECTIVES: Hybrid ablation of atrial fibrillation (AF) is a promising treatment strategy; however, data regarding its efficacy and safety are still limited. METHODS: Patients with non-paroxysmal AF were enrolled. First, a thoracoscopic, epicardial isolation of pulmonary veins and the left atrial posterior wall ('box lesion') was performed; a novel unipolar/bipolar radiofrequency device was used. Moreover, in 12 patients enrolled thereafter, the left atrial appendage was occluded...

In an effort to improve the technical success rates and clinical outcomes of radiofrequency (RF) ablation, Yan et al validated the use of a tumor-penetrating peptide and thermosensitive doxorubicin (DOX)-loaded nanoparticles in combination with RF ablation in a hepatocellular carcinoma mouse model. By achieving higher chemotherapeutic drug concentrations in target lesions, fewer toxic effects, and improved survival end points in an animal tumor model, the authors conclude that superior tumor treatment with RF ablation is possible when combined with molecular-targeted drug delivery systems...

INTRODUCTION: Radiofrequency (RF) ablation is effective for slow pathway ablation, but carries a risk of inadvertent AV block requiring permanent pacing. By comparison, cryoablation with a 4 mm distal electrode catheter has not been reported to cause permanent AV block but has been shown to be less effective than RF ablation. We sought to define the safety and efficacy of a 6 mm distal electrode cryoablation catheter for slow pathway ablation in patients with atrioventricular nodal reentry tachycardia (AVNRT)...

With the development of molecular targeting therapy, several treatment options for advanced hepatocellular carcinoma (HCC) have become available in cases where curative and other palliative treatments, such as radiofrequency ablation, surgical resection, and transarterial chemoembolization, are not applicable. However, with the detection of a variety of mutations in cancer-related genes in a single tumor, molecular heterogeneity is commonly observed in HCC. Therefore, mutations in the major cellular signaling pathways underlie the development of resistance to molecular targeting agents...

BACKGROUND: Non-hypervascular hypointense hepatic nodules during the hepatobiliary phase of gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid (Gd-EOB-DTPA)-enhanced MRI have been reported to be associated with intrahepatic distant recurrence (IDR) after hepatectomy or radiofrequency ablation (RFA) for hepatocellular carcinoma (HCC). IDR is categorized into hypervascular transformation of non-hypervascular hypointense hepatic nodules and new intrahepatic recurrence. The aim of this study was to evaluate the relationship between non-hypervascular hypointense hepatic nodules on Gd-EOB-DTPA-enhanced MRI and IDR after RFA, focusing on new intrahepatic recurrence...

BACKGROUND: Interferon-based antiviral therapies against hepatitis C virus (HCV) infection have been shown to reduce the incidence of hepatocellular carcinoma (HCC) in patients with sustained viral response (SVR). Recently, direct-acting antivirals (DAAs) have been proven to be much more effective in achieving SVR than interferon-based therapies. However, whether DAAs can efficiently prevent the occurrence of HCC after SVR remains controversial. To clarify this issue, we analyzed the clinical features of patients in whom HCC developed after achievement of SVR with DAAs for chronic HCV infection...

BACKGROUND: Routine radiofrequency ablation (RFA) of an incompetent perforator vein (IPV) using the standard treatment protocol at 85°C has a treatment time of 6 minutes. To make treatment time more efficient, we sought to determine the effect of a shortened protocol for radiofrequency stylet (RFS) ablation by comparing the early success using three different temperatures: 85°C, 90°C, and 95°C. METHODS: A retrospective study examined 642 procedures of IPV closures in 255 patients with varying degrees of venous insufficiency treated with RFA from 2009 to 2015...

The use of immunomodulation to treat malignancies has seen a recent explosion in interest. The therapeutic appeal of these treatments is far reaching, and many new applications continue to evolve. In particular, immune modulating drugs have the potential to enhance the systemic anticancer immune effects induced by locoregional thermal ablation. The immune responses induced by ablation monotherapy are well documented, but independently they tend to be incapable of evoking a robust antitumor response. By adding immunomodulators to traditional ablative techniques, several researchers have sought to amplify the induced immune response and trigger systemic antitumor activity...

Radiofrequency ablation of Barrett's esophagus with low-grade dysplasia is recommended in recent American College of Gastroenterology guidelines, with endoscopic surveillance considered a reasonable alternative. Few studies have directly compared outcomes of radiofrequency ablation to surveillance and those that have are limited by short duration of follow-up. This study aims to compare the long-term effectiveness of radiofrequency ablation versus endoscopic surveillance in a large, longitudinal cohort of patients with Barrett's esophagus, and low-grade dysplasia...
