AIMS Atrial fibrillation ablation requires peri-procedural oral anticoagulation (OAC) to prevent thromboembolic events. There are several options for OAC. We evaluate peri-procedural AF ablation complications using a variety of peri-procedural OACs. METHODS AND RESULTS We examined peri-procedural OAC and groin, bleeding, and thromboembolic complications for 2334 consecutive AF ablations using...

PURPOSE OF REVIEW The purpose of the review is to provide an update on the safety and efficacy of catheter cryoablation. RECENT FINDINGS Catheter cryoablation is a safe and clinically effective method for ablation of atrioventricular nodal reentrant supraventricular tachycardia. Although the acute procedural success rate of catheter cryoablation for this arrhythmia may be slightly lower than ...

OBJECTIVE To investigate whether the factors related to the patient and the disease have any effect on the success of ablation therapy in patients with differentiated thyroid cancer who have received I-131 ablation therapy. MATERIAL AND METHODS All the patients with differentiated thyroid cancer were referred for I-131 ablation therapy after thyroidectomy between July 2007 and September 2009....

A magnetohydrodynamic numerical model for hydrogenic pellet ablation in the electrostatic approximation has been developed based on the method of front tracking. The main features of the model are the explicit tracking of interfaces that separate the solid pellet from the ablated gas and the cold, dense and weakly ionized ablation cloud from the highly conducting fusion plasma, a surface ablati...

BACKGROUND Barrett's esophagus, a condition of intestinal metaplasia of the esophagus, is associated with an increased risk of esophageal adenocarcinoma. We assessed whether endoscopic radiofrequency ablation could eradicate dysplastic Barrett's esophagus and decrease the rate of neoplastic progression. METHODS In a multicenter, sham-controlled trial, we randomly assigned 127 patients with dy...

In order to assess the efficacy of hysteroscopic endometrial ablation and factors which are important in it's success, a prospective, randomized study was performed in Shiraz university hospitals between Sep. 1995 to Feb. 1998. 50 patients with chief complaints of menorrhagia that were in reproductive age (25- 50 years) and had shown no response to medication and D&C underwent endometrial ...

Debris cover is widely present in glacier ablation areas of the Tibetan Plateau, and its spatial distribution greatly affects glacier melt rates. High-resolution in situ measurements of debris thickness on Hailuogou glacier, Mount Gongga, southeastern Tibetan Plateau, show pronounced inhomogeneous debris distribution. An analysis of transverse and longitudinal profiles indicates that the ground...

Background/introduction Obstruction by the thoracic cage of the high intensity focused ultrasound (HIFU) beam is one of the major challenges in the ablation of abdominal lesions. Several beam shaping methods have been proposed to reduce exposure of the ribs to acoustic energy and to recover focal point intensity. The feasibility of HIFU ablation of a clinically relevant volume applying beam sha...

In the last few years, minimally invasive tumor ablation performed by interventional radiologists has gained increasing relevance in oncologic patient care. Limitations of thermal ablation techniques such as radiofrequency ablation (RFA), microwave ablation (MWA), and laser-induced thermotherapy (LITT), including large tumor size, cooling effects of adjacent vessels, and tumor location near the...

PURPOSE To investigate the feasibility, safety, and efficacy of single-session ethanol ablation with multipronged needles in the treatment of early-stage hepatocellular carcinoma (HCC). MATERIALS AND METHODS A pilot clinical study enrolled 20 patients with Child-Pugh A-B cirrhosis (15 men and 5 women 53-84 years old [mean 70.3 years old ± 8.3, median 72 years old]) and with 25 HCC tumors 1.2-...
