radiofrequency ablation of the atrioventricular node in patients with His-bundle pacing Alwin Zweerink, Alwin Zweerink Department of Cardiology, University Hospital of Geneva, Rue Gabrielle-Perret-Gentil 4, CH-1211 Geneva, Switzerland. Search for other works by this author on: 2002-03-01 When considering the specific complications, only thrombocytopenia (OR = 51.13, 95% CI: 2.92-894.21) and renal impairment (OR = 4.19, 95% CI: 1.34-13.11) but not other complications were significantly higher in the cryoablation group.In conclusion, the 2 methods had almost equal mortality and nonsignificant difference in local tumor progression, with higher risk of complications in cryoablation. Radio-frequency ablation and cryoablation are both effective in the treatment of renal masses measuring 3 cm or smaller (Atwell et al. 2013). Major complications with either procedure are infrequent. Meta-analyses demonstrate a major complication rate of 3 % for percutaneous treatment vs.

However, first-line ablation may be Cryoablation for Atrial Fibrillation Patients with symptomatic, paroxysmal, untreated atrial fibrillation were randomly assigned to antiarrhythmic drug Compared with RF ablation, cryoablation present a comparable long-term AF/atrial tachycardial-free survival and procedure-related adverse events. Meanwhile, cryoablation markedly shorten the procedure time, nonetheless, with negligible impact on the fluoroscopy time. Outcomes data were retrospectively collected and analyzed to compare recurrence rates for patients undergoing radiofrequency ablation (n = 41) versus cryoablation (n = 70). Cryoablation is a process that uses extreme cold to destroy tissue.Cryoablation is performed using hollow needles (cryoprobes) through which cooled, thermally conductive, fluids are circulated.

Methods: This retrospective cohort study used 2013–2014 records from the Premier Healthcare Database for adults with AF catheter ablation. Exclusions included non-AF ablation, surgical ablation, valve replacement or repair, or cardiac The Cryoballoon vs Irrigated Radiofrequency Catheter Ablation (CIRCA) study was designed to compare the effectiveness of PVI performed by advanced generation catheter ablation technologies (contact force guided RF ablation and second-generation cryoballoon-based ablation), and the DOuble Short vs Standard Exposure Duration study (DOSE) was designed to assess optimal cryotherapy dosing. Background Effective treatment of paroxysmal atrial fibrillation (AF) is essential for reducing the risk of stroke and heart failure. Cryoballoon (CB) ablation has been developed as an alternative to the use of radiofrequency (RF) energy for electrical isolation of the pulmonary veins. Herein, we provide long-term data regarding the efficacy of CB ablation in comparison to RF. Methods FreezeAF Keywords: hepatocellular carcinoma, transcatheter arterial chemoembolization, microwave ablation, cryoablation, combination therapy.

To compare the clinical outcomes between radiofrequency ablation (RFA) and cryoablation for the treatment of clinical T1b (cT1b) renal cell carcinoma (RCC). The data of 46 patients [(39 men and 7 women, median age; 73 years, range 39–87 years)] were gathered from 3 institutions. Cryoablation is a new non surgical alternative treatment for certain cancers. It has advantages over standard keyhole surgery in that it is incisionless, mea Cryoablation or radiofrequency ablation of the small renal mass : a meta-analysis. Cancer 2008; 113:2671.

2016-06-16 · Radiofrequency (RF) ablation utilizes a RF current that is applied in a point-by-point mode, heating the tissue and leading to cellular necrosis. 4 Cryogenic ablation induces necrosis by pumping refrigerant (N 2 O) through a balloon in a single-step mode, thereby freezing the tissue. 4,5 Both methods are approved by the US Food and Drug Administration (FDA) for treatment of paroxysmal AF. No statistical differences were observed following Cryo or MWA in median tumor size (p = 0.6), mRENAL (p = 0.1) or technical success (p = 0.8). Median procedure time was significantly lower using microwave ablation (p = 0.003). Median follow-up time was similar in the two groups (22 and 20 months, respectively). Se hela listan på 2016-06-16 · Total procedure duration and left atrial dwell time were shorter in the cryoablation than in the RF group, although fluoroscopy time was slightly longer (Table 2). The study authors stated that circumferential single-step ablations utilized by cryoablation require less time.

Once the probes are in place, the attached cryogenic freezing unit removes heat from the tip of the probe and by extension from the surrounding tissues. Ablation occurs in tissue When considering the specific complications, only thrombocytopenia (OR = 51.13, 95% CI: 2.92-894.21) and renal impairment (OR = 4.19, 95% CI: 1.34-13.11) but not other complications were significantly higher in the cryoablation group.In conclusion, the 2 methods had almost equal mortality and nonsignificant difference in local tumor progression, with higher risk of complications in cryoablation. Cryoablation is a minimally invasive procedure in which the EP doctor uses a thin flexible tube, known as a balloon catheter, to locate and freeze this heart tissue. Cryoablation is an appropriate treatment for atrial fibrillation when medications and other AF treatments do not restore the heart to a normal rhythm. It's called catheter ablation, and there are two common methods used today: radiofrequency (RF) and cryoablation (cryo).
