INTRODUCTION: Recurrences within the blanking period (early recurrences) are common after atrial fibrillation (AF) ablation by pulmonary vein isolation (PVI), but their clinical significance is still controversial. We aimed at evaluating the significance of within-blanking recurrences at 12-month follow-up after cryoballoon (CB) PVI, and to assess the real procedural success rate by continuous monitoring of cardiac rhythm. METHODS AND RESULTS: Sixty consecutive AF patients (34 paroxysmal, 56...

CONTEXT: Laparoscopic cryoablation (LCA) and percutaneous cryoablation(PCA) have been used on patients with small renal masses(SRMs) for many years. However, clinical studies assessing their feasibility and safety have reported contradictory outcomes. This systematic evaluation was performed to obtain comprehensive evidence with regard to the feasibility and safety of PCA compared with LCA. METHODS: A systematic search of Embase, Pubmed, Medline, the Cochrane Library were performed to identify studies that compared LCA with PCA were published up to Mar 2016...

BACKGROUND: Liquid nitrogen has been used as adjuvant cryotherapy for treating giant cell tumor (GCT) of bone. However, the liquid phase and ultrafreezing (-196° C) properties increase the risk of damage to the adjacent tissues and may lead to perioperative complications. A novel semisolid cryogen, freezing nitrogen ethanol composite, might mitigate these shortcomings because of less-extreme freezing. We therefore wished to evaluate freezing nitrogen ethanol composite as a coolant to determine its properties in tumor cryoablation...

OBJECTIVE: Most patients with atrial fibrillation (AF) undergoing cardiac surgery do not receive concomitant ablation. This study reviewed outcomes of patients with AF undergoing Cox-maze IV (CMIV) procedure with radiofrequency and cryoablation and coronary artery bypass grafting (CABG) at our institution. METHODS: Between the introduction of radiofrequency ablation in 2002 and 2015, 135 patients underwent left- or biatrial CMIV with CABG. Patients undergoing other cardiac procedures, except mitral valve repair, or who had emergent, reoperative, or off-pump procedures were excluded...

REVIEW
A Tomasian, A N Wallace, J W Jennings
Minimally invasive percutaneous imaging-guided techniques have been shown to be safe and effective for the treatment of benign tumors of the spine. Techniques available include a variety of tumor ablation technologies, including radiofrequency ablation, cryoablation, microwave ablation, alcohol ablation, and laser photocoagulation. Vertebral augmentation may be performed after ablation as part of the same procedure for fracture stabilization or prevention. Typically, the treatment goal in benign spine lesions is definitive cure...

A 38-year-old female patient with a history of tetralogy of Fallot repair at 10 years of age underwent pulmonary valve replacement with a mechanical prosthesis, tricuspid annuloplasty, and right ventricular outflow tract cryoablation due to pulmonary regurgitation, tricuspid regurgitation, and multiple premature ventricular contractions with sustained ventricular tachycardia. After surgery, she had an uneventful postoperative course with arrhythmia monitoring. She was discharged without incident, and a follow-up Holter examination showed a decrease in the number of ventricular ectopic beats from 702 to 41...

CLINICAL/METHODICAL ISSUE: In the treatment of localized renal cell carcinoma, the lack of randomization in controlled trials on thermal ablation is a major limitation. The latter leads to significant study bias and it ultimately remains unclear whether the improved overall survival in favor of partial nephrectomy can actually be attributed to the treatment method. STANDARD RADIOLOGICAL METHODS: For T1a (≤4 cm) renal cell carcinoma without lymph node and distant metastases, excellent technical and clinical results have been described after imaging-guided radiofrequency ablation and cryoablation...

OBJECTIVE: The aim of this study was to establish a suitable rabbit model and select the optimal protocol for laparotomy cryoablation of pancreatic carcinoma. METHODS: VX2 tumor tissues were inoculated into rabbit pancreases to build the pancreatic carcinoma model; then, the tumor-bearing rabbits were randomly divided into 4 groups: control, treatment A (the cryoablated-iceball diameter was bigger than the tumor), treatment B (iceball was as big as the tumor), and treatment C (iceball was smaller than the tumor)...

REVIEW
K Farrag, S Sriprasad
A large number of small renal masses (SRMs) with size less than 4 cm are being identified due to advances in diagnostic imaging. As the natural history of these tumours remains unknown, there is no reliable way to predict their behaviour or future growth. Although, partial nephrectomy is the gold standard for treatment of these tumours, ablative non-surgical therapies such as cryoablation and radiofrequency ablation provide a less invasive option of treatment with comparable oncological outcomes. In this systematic review, the principle, indications, methods of treatment, oncological control, complication and renal function of ablative therapies are critically reviewed...

Cryoablation for atrial fibrillation (AF) has rapidly become a mainstream treatment for AF. In this report, 163 patients who had undergone a cryoablation procedure at one clinical center were contacted by telephone 33.1 ± 3.3 months after the procedure. All patients had received cryoablation of the pulmonary vein ostia, although concomitant procedures were performed at the same time in over 50% of the patients, including radiofrequency and/or cryoablation of other areas of the left atrium. Freedom from a repeat ablation procedure was 87%, while freedom from recurrent hospitalization for AF was 89%, as compared to previous reports of 65%...

INTRODUCTION: Cryoablation (CA) is a minimally invasive modality for the management of small renal cortical neoplasms (RCN). Successful ablation is dependent on achieving target temperatures during CA that result in tumor cell death. We investigated long-term oncological outcomes following CA using Multi-Point Thermal Sensors (MTS), which allow precise temperature determination at four points along the needle. METHODS: We performed a retrospective review of 20 patients with < 4 cm RCN who underwent de novo CA from 2005 to 2009...

OBJECTIVE: Atrial fibrillation (AF) is the most common sustained arrhythmia and is associated with increased morbidity and mortality. Atrial fibrosis augments recurrence rate following AF catheter ablation. Osteopontin is a multifunctional molecule involved in several pathophysiological pathways, including fibrosis. Presently described is investigation of relationship between serum osteopontin level and AF recurrence after AF cryoablation. METHODS: The study was designed to be prospective and observational; 60 patients with paroxysmal (n=47) and persistent (n=13) AF were included...

We analyzed the effectiveness of using 64-slice spiral computed tomography (CT) and perfusion imaging to guide argon-helium cryoablation treatment of liver cancer. In total, 60 cases of advanced hepatocellular carcinoma before surgery treated with argon-helium cryoablation were inlcuded in the present study. Retrospective summary of the 60 cases of metaphase and advanced liver cancer were used as the control group. The control group were treated using cryoablation with argon-helium knife. We used enhanced scanning with 64-slice spiral CT to define the extent of their lesions and prepared a plan of percutaneous cryoablation for the treatment...
