radiofrequency ablations

AIMS: Pulmonary vein isolation (PVI) for paroxysmal atrial fibrillation (PAF) using very high-power short-duration (vHPSD) radiofrequency (RF) ablation proved to be safe and effective. However, vHPSD applications result in shallower lesions that might not be always transmural. Multidetector computed tomography-derived left atrial wall thickness (LAWT) maps could enable a thickness-guided switching from vHPSD to the standard-power ablation mode. The aim of this randomized trial was to compare the safety, the efficacy, and the efficiency of a LAWT-guided vHPSD PVI approach with those of the CLOSE protocol for PAF ablation (NCT04298177)...

BACKGROUND: The aim of this study was to compare the efficacy of laparoscopic liver resection versus radiofrequency ablation for treatment of small hepatocellular carcinoma. METHODS: This single-centre RCT was conducted at a tertiary referral centre in China. Patients with small hepatocellular carcinoma who had a single nodule no larger than 5 cm, or up to three nodules of 3 cm or smaller, were eligible. Patients were assigned randomly in a 1 : 1 ratio to either laparoscopic liver resection or radiofrequency ablation...

INTRODUCTION: Trigeminal neuralgia (TGN) poses a therapeutic challenge, particularly within the context of multiple sclerosis (MS). This study aimed to conduct a comprehensive meta-analysis and systematic review of four less-invasive treatment modalities for TGN in MS patients, namely, gamma knife radiosurgery (GKRS), glycerol rhizotomy (GR), balloon compression (BC), and radiofrequency ablation (RFA). METHODS: Single-armed meta-analyses were employed to assess the overall efficacy of each treatment, while double-armed analyses compared the efficacy between different treatment options in double-armed studies...

OBJECTIVE: Investigate the capacity of MRI to evaluate efficacy of radiofrequency (RF) ablations delivered to MRI-defined arrhythmogenic substrates. METHODS: Baseline MRI was performed at 3T including 3D LGE in a swine model of chronic myocardial infarct (N=8). MRI-derived maps of scar and heterogeneous tissue channels (HTCs) were generated using ADAS 3D. Animals underwent electroanatomic mapping and ablation of the left ventricle in CARTO3, guided by MRI-derived scar maps...

Objective: Warthin's tumors of the parotid gland can be safely observed. Definitive treatment usually requires parotidectomy under general anesthesia. The decision to operate on Warthin's tumors of the parotid gland can be complicated in patients who wish to avoid risks of surgery and general anesthesia. This systematic review explores the potential of radiofrequency ablation (RFA) as a minimally invasive alternative. Methods: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) model was used to collect 3 relevant studies that focused on RFA treatment for Warthin's tumors...

BACKGROUND AND AIMS: Using thermal-based energy sources (radiofrequency energy (RF)/cryo energy) for catheter ablation is considered effective and safe when performing pulmonary vein isolation (PVI) in patients with paroxysmal atrial fibrillation (AF). However, treatment success remains limited and complications can occur due to the propagation of thermal energy into nontarget tissues. We aim to compare pulsed field ablation (PFA) with RF ablation in terms of efficacy and safety for patients with drug-resistant paroxysmal AF...

This is a case of a 13-year-old male with frequent premature ventricular contractions with QRS configurations of the left superior axis and left bundle branch block, which originated from the posterior-superior process of the left ventricle. Premature ventricular contractions were successfully eliminated by delivering radiofrequency energy to the inferior wall of the right atrium without causing either junctional rhythm or atrioventricular block. Ventricular arrhythmias originating from this site have been sporadically reported in adults; however, this is the first report in a child...

PURPOSE: To compare the prognosis of complete and insufficient ablation of transarterial chemoembolization (TACE) combined with radiofrequency ablation (RFA) in treating medium and large hepatocellular carcinoma (HCC) and to explore the differences in recurrence patterns between the two groups. PATIENTS AND METHODS: Patients´ medical records and imaging data of patients with confirmed HCC from January 2014 to January 2022 were collected. These patients were divided into 2 groups: complete ablation (n=172) and insufficient ablation (n=171)...

Hepatocellular carcinoma (HCC) presents a malignant pathology known for its high early recurrence rate following curative treatment, significantly impacting patient prognosis. Currently, effective strategies to mitigate early HCC recurrence remain undetermined. In this report, we document a case of HCC managed with curative radiofrequency ablation (RFA), particularly in a patient facing a high risk of early recurrence due to a substantial tumor size. In an effort to forestall recurrence, immune checkpoint inhibitors (ICIs) were preemptively administered for 6 months post-RFA...

BACKGROUND/OBJECTIVE: Treatment of hepatocellular carcinoma (HCC) with ablation alone often results in high rates of recurrence and metastasis, reaching up to 25.9% within two years. Therefore, this study aimed to examine the efficacy and safety of transarterial chemoembolization (TACE)-assisted multi-image guided radiofrequency ablation (RFA) for the treatment of stage Ia HCC according to the China liver cancer staging (CNLC). METHODS: This study enrolled and analyzed a total of 118 patients diagnosed with HCC, each with a single nodular lesion no larger than 5 cm, who received TACE-RFA as first-line therapy between February 1, 2014, and December 31, 2021...

Post-mastectomy pain syndrome (PMPS) is a syndrome broadly applied to the development of chronic pain after surgical breast intervention (i.e., lumpectomy and mastectomy). The incidence of PMPS is likely underreported, and this has contributed to a paucity of high-level evidence related to the treatment of the aforementioned condition. A drive to reduce the burden of opioid use has led to pain management physicians trialing a variety of strategies to help patients manage PMPS. This review discusses the latest evidence behind treatment options for PMPS, exploring medications as well as interventional techniques (e...

The clinical use of irreversible electroporation in invasive cardiac laboratories, termed pulsed field ablation (PFA), is gaining early enthusiasm among electrophysiologists for the management of both atrial and ventricular arrhythmogenic substrates. Though electroporation is regularly employed in other branches of science and medicine, concerns regarding the acute and permanent vascular effects of PFA remain. This comprehensive review aims to summarize the preclinical and adult clinical data published to date on PFA's effects on pulmonary veins and coronary arteries...

UNLABELLED: Non-reentrant fascicular tachycardia (NRFT) developed in a 6-year-old Japanese boy. Because of drug-resistant recurrences, he received catheter mapping and ablation at age 10 years. An electrocardiogram exhibited a superior left-axis deviation, a right bundle branch block-type configuration, and relatively narrow QRS with sharp R wave. It suggested verapamil-sensitive ventricular tachycardia (VT), but showed no sensitivity to verapamil or reentrant characteristics in the electrophysiological study...

BACKGROUND: Proactive esophageal cooling is FDA cleared to reduce the likelihood of esophageal injury during radiofrequency ablation for treatment of atrial fibrillation (AF). Long-term follow-up data have also shown improved freedom from arrhythmia with proactive esophageal cooling compared to luminal esophageal temperature (LET) monitoring during pulmonary vein isolation (PVI). One hypothesized mechanism is improved lesion contiguity (as measured by the Continuity Index) with the use of cooling...

Persistent knee pain in patients around the fifth decade of life is a frequent cause of attention in rehabilitation consultations. The most common cause of diagnosis is knee osteoarthritis, considering the existence of different degrees seen in simple radiographies. The advanced degrees present joint space reduction, osteophytosis and subchondral sclerosis; however, in the initial degrees, the findings are more subtle and sometimes nonexistent for conventional radiology. Clinical ultrasound has partly come to fill this «diagnostic gap», making it possible to detect meniscal extrusions and small osteophytes as signs of incipient osteoarthritis and to relate them as triggers of pain...

PURPOSE: To present the effectiveness and safety of radiofrequency ablation (RFA) in parathyroid adenoma (PTA). MATERIALS AND METHODS: In this retrospective study, 60 patients with a single PTA were evaluated for changes in biochemical and ultrasonographic features up to 6 months after RFA of the lesion. Adenomas were ablated with an alternative technique so called "Nik jet dissection" which incorporates full hydrodissection and polar artery coagulation. Complications as well as the variations in biochemical data and nodule volumes were analyzed between baseline measurements and at each follow-up interval data (first day, 1, 3, and 6 months after ablation) were analyzed...

BACKGROUND: Recurrence of paroxysmal atrial fibrillation (AF) following pulmonary vein isolation (PVI) is presumably caused by pulmonary vein (PV) reconnections. However, there is little data available on the durability of PVI and incidence of arrhythmia recurrence in patients with persistent AF. OBJECTIVES: To evaluate the lesion durability by means of an a priori planned remapping procedure in patients with persistent AF undergoing CLOSE-guided PVI. METHODS: In a prospective study, we included patients with symptomatic, persistent AF undergoing CLOSE-guided radiofrequency ablation...

BACKGROUND: Background • Radiofrequency ablation, a widely utilized minimally invasive surgery for atrial fibrillation treatment, has certain latent risks, including a high postoperative recurrence rate and various complications. Therefore, nursing intervention plays a pivotal role in the rehabilitation process after radiofrequency ablation. BACKGROUND: Objective • This study aims to investigate the impact of rehabilitation nursing on postoperative cardiac function and quality of life in patients with atrial fibrillation...

Fully CMR-guided electrophysiological interventions (EP-CMR) have recently been introduced but data on the optimal CMR imaging protocol are scarce. This study determined the clinical utility of 3D non-selective whole heart steady-state free precession imaging using compressed SENSE (nsWHcs) for automatic segmentation of cardiac cavities as the basis for targeted catheter navigation during EP-CMR cavo-tricuspid isthmus ablation. Fourty-two consecutive patients with isthmus-dependent right atrial flutter underwent EP-CMR radiofrequency ablations...
