Cryoablation is one of treatment modalities for kidney cancer and is expected to induce strong local immune responses as well as systemic T-cell-mediated immune reactions that may lead to the regression of distant metastatic lesions. Thus, the characterization of T cell repertoire and immune environment in tumors before and after treatment should contribute to the better understanding of the cryoablation-induced anticancer immune responses. In this study, we collected tumor tissues from 22 kidney cancer patients, before cryoablation and at 3 mo after cryoablation...

BACKGROUND: Cardiophrenic angle lymph node metastases are relatively rare. Surgical resection is the main treatment for cardiophrenic angle lymph node metastasis, but it is not always possible. CASE PRESENTATION: Here, we report our initial experience with cryoablation of a cardiophrenic angle lymph node metastasis from liver cancer. As the cardiophrenic angle lymph node metastasis was located close to the heart, about 200 mL of 0.9% saline was injected into the pericardium to separate the heart from the target area...

BACKGROUND Percutaneous catheter radiofrequency ablation (RFA) and cryoablation of the left atrium and pulmonary vein ostia have become successful therapeutic modalities in the management of atrial fibrillation. Atrio-esophageal fistula is a rare complication. Awareness of complication risk is imperative because without prompt diagnosis and urgent surgical intervention, the outcome is often fatal. We present 3 cases of atrio-esophageal fistula following percutaneous catheter radiofrequency ablation (RFA). CASE REPORT Case 1: A 72-year old white male presented 27 days after percutaneous RFA for atrial fibrillation with fever, altered mental status, and melena...

BACKGROUND: Experience with percutaneous epicardial ablation of tachyarrhythmia in pediatrics is limited. This case series addresses the feasibility, safety and complications of the procedure in children. METHODS: A total of 9 patients underwent 10 epicardial ablation procedures from 2002 to 2013 at two academic centers. Activation mapping was performed in all cases, and electro-anatomic map was utilized in 9 of the 10 procedures. Patients had undergone 1-3 failed endocardial catheter ablations in addition to medical management, and all had symptoms, a high-risk accessory pathway (AP), aborted cardiac arrest with Wolff-Parkinson-White syndrome (WPW) or ventricular dysfunction...

<i>Background</i> The standard treatment of T1 renal cell carcinoma is (partial-) nephrectomy. For patients where surgery is not the treatment of choice, for example in the elderly, in case of severe comorbidity, inoperability or refusal of surgery, alternative treatment options are available. These treatment options include active surveillance, radiofrequency ablation, cryoablation, microwave ablation or stereotactic body radiotherapy. In the present overview, the efficacy, safety and outcome of these different options are summarized, particularly focusing on recent developments...

BACKGROUND AND AIMS: Early esophageal squamous cell neoplasia (ESCN) can be successfully treated by endoscopic mucosal resection (EMR), endoscopic submucosal dissection (ESD), or radiofrequency ablation (RFA). A new portable, battery-powered cryotherapy system using nitrous oxide (cryoballoon focal ablation system (CbFAS) has been used for Barrett's esophagus. It consists of a small hand-held device containing liquid nitrous oxide, which converts to gas within a low-pressure-compliant through-the-scope balloon and freezes targeted mucosa in contact with the balloon...

Tumor-induced osteomalacia (TIO) is a debilitating paraneoplastic condition caused by small phosphaturic mesenchymal tumors (PMTs) that secrete large amounts of the phosphate- and vitamin D-regulating hormone, FGF23. Tumor removal results in cure. However, due to high perioperative comorbidity, either from tumor location or host factors, surgery is sometimes not an option. Tumor destruction via cryoablation may be an effective option for inoperable PMTs. Three subjects with a confirmed diagnosis of TIO were studied...

BACKGROUND: Cryoablation for AVNRT is associated with higher recurrence rates than radiofrequency ablation(RF). Junctional tachycardia marks procedural success with RF, but no such indicator exists for cryoablation. OBJECTIVE: To determine the impact of voltage mapping plus longer ablation lesions on mid-term success of cryoablation for children with AVNRT. METHODS: A single-center retrospective analysis was performed of pediatric patients with AVNRT who underwent cryoablation from 2011-2015...

AIM: To evaluate the long-term outcome of catheter ablation of atrial fibrillation (AF) facilitated by preprocedural three-dimensional (3-D) transesophageal echocardiography. METHODS: In 50 patients, 3D transesophageal echocardiography (3D TEE) was performed immediately prior to an ablation procedure (paroxysmal AF: 30 patients, persistent AF: 20 patients). The images were available throughout the ablation procedure. Two different ablation strategies were used. In most of the patients with paroxysmal AF, the cryoablation technique was used (Arctic Front Balloon, CryoCath Technologies/Medtronic; group A2)...

Partial nephrectomy is the treatment of choice for small renal cell carcinoma (RCC) from the perspective of cancer management and renal function. However, when patients with RCC are of advanced age, exhibit severe comorbidities, including cardiovascular and pulmonary diseases, or have hereditary RCC, ablative therapies, including radiofrequency ablation (RFA) and cryoablation are useful treatment options. In the present study, the clinical outcomes of percutaneous RFA for treating small RCC were evaluated. Between December 2005 and March 2015, 40 patients (41 renal tumors in total) underwent RFA and a total of 50 sessions of RFA were performed...
