REVIEW
Mingming Zhu, Ziqi Sun, Chin K Ng
Thermal ablation techniques such as radiofrequency, microwave, high intensity focused ultrasound (HIFU) and laser have been used as minimally invasive strategies for the treatment of variety of cancers. MR thermometry methods are readily available for monitoring thermal distribution and deposition in real time, leading to decrease of incidents of normal tissue damage around targeted lesion. HIFU and laser-induced thermal therapy (LITT) are the two widely accepted tumor ablation techniques because of their compatibility with MR systems...

Our previous phase I/IIA study showed that autologous dendritic cells (DCs) pulsed with tumor-associated antigens are well tolerated in patients with hepatocellular carcinoma (HCC). In this randomized, multicenter, open-label, phase II trial, we investigated the efficacy and safety of this DC-based adjuvant immunotherapy with 156 patients, who treated for HCC with no evidence of residual tumor after standard treatment modalities. Patients were randomly assigned to immunotherapy (n = 77; injection of 3 × 10(7) DC cells, six times over 14 weeks) or control (n = 79; no treatment)...

BACKGROUND AND PURPOSE: Osteoid osteoma is an infrequent but debilitating benign bone lesion which can be successfully managed by percutaneous radiofrequency ablation (RFA). There are few studies investigating the efficacy and follow-up of this treatment. An arbitrary upper limit of 15 mm has been used to differentiate between osteoid osteoma and osteoblastoma with surgery used for lesions above this limit. We aimed to analyse the cases identified from our prospectively maintained database over a ten year period since adoption of this technique in our unit...

BACKGROUND AND OBJECTIVES: Combination of transcatheter arterial chemoembolization (TACE) and radiofrequency ablation (RFA) has become an effective alternative therapy for hepatocellular carcinoma (HCC). In clinical practice, the choice of time interval between TACE and RFA is a key point for curative effect, but optimal time interval is uncertain in guidelines. We aim to explore the optimal time interval for HCC patients of Child-Pugh classification A or B. METHODS: Two hundred and thirty-three HCC patients of Child A or B who had undergone TACE and RFA were enrolled and divided into seven groups according to different time intervals (1-7weeks)...

We report the case of a 57-year-old man with a history of ischemic cardiomyopathy who presented to the hospital with recurrent episodes of ventricular tachycardia refractory to antiarrhythmic medications. Mapping identified a deep premature ventricular contraction focus in the anterolateral papillary muscle, an area that has been previously identified as difficult to treat with radiofrequency catheter ablation. The hospital course was complicated by cardiogenic shock and VT-storm, and the patient ultimately underwent surgical resection of the anterolateral papillary muscle with left ventricular assist device placement as a successful bridge to cardiac transplantation...

BACKGROUND: Atrioventricular nodal reentry tachycardia (AVNRT) is common in adults and often involves reentry through two or more AV nodal-atrial connections. Although AVNRT can be a trigger for atrial fibrillation (AF), we have observed new onset AVNRT after AF ablation procedures. OBJECTIVE: To determine whether ablation involving the septum or proximal coronary sinus during AF ablation may create a substrate favorable for AVNRT METHODS: Cases of ablation for persistent AF who required a repeat ablation procedure between 2009 to 2016 were reviewed for diagnosis of AVNRT...

Radiofrequency endometrial ablation resulted in abrupt cessation of acute abnormal uterine bleeding in one case, avoiding emergency hysterectomy. Acute abnormal uterine bleeding (AUB) unrelated to pregnancy is defined as an episode of bleeding that is sufficient in volume in the opinion of the treating clinician to require urgent or emergency intervention.(1) Acute AUB is a distressing condition that poses a challenge for clinicians and consumes healthcare resources.

BACKGROUNDS: The parietal band is one of the muscle bands in the right ventricle. This study investigated the electrocardiographic and electrophysiological characteristics and ablation outcome of idiopathic ventricular arrhythmias (VAs) originating from the parietal band. METHODS AND RESULTS: We studied 14 patients with idiopathic VA origins in the parietal band among 294 consecutive patients with VA origins in the right ventricle. The QRS morphologies of the parietal band VAs were characterized by a left bundle branch block and left inferior (n=12) or superior (n=2) axis pattern with the presence of a notch in the middle of the QRS in all cases, precordial transition at ≤lead V3 in 7 patients, and a slow QRS onset in 4 patients...

Patients with early-stage hepatocellular carcinoma (HCC) are potential candidates for curative treatments such as radiofrequency ablation (RFA), surgical resection (SR), or liver transplantation (LT), which have demonstrated a significant survival benefit. We aimed to estimate the cost-effectiveness of curative and combination treatment strategies among patients diagnosed with HCC during 2002-2010. This study used Ontario Cancer Registry-linked administrative data to estimate effectiveness and costs (2013 USD) of the treatment strategies from the healthcare payer's perspective...

BACKGROUND: The most likely origin of PVCs may be deduced from surface ECG analysis while planning an electrophysiological study (EPS). Apart from purely benign forms of increased ventricular ectopy, myocardial substrate (e.g., regional fibrosis) may be present in certain cases, which will significantly impact the ablation approach. CMR imaging can reliably identify fibrotic target lesions and, hence, may assist in adequate patient selection and procedural planning. METHODS AND RESULTS: We analyzed 101 patients (59% male, mean age 57...
