Atrioventricular Junction Ablation Transvenous ablation of the atrioventricular (AV) junction was first performed with direct-current shocks in 1981.1 Radiofrequency energy replaced direct-current shocks for AV junction ablation because of improved efficacy and safety.2 Radiofrequency ablation of the AV junction has a success rate .95% and is associated with a low incidence of adverse effects.3...

Introduction Catheter ablation plays an important role in the management of persistent atrial fibrillation (AF), though recurrences of AF following ablation in patients with this condition remains high. There is general agreement that catheter ablation for AF should include pulmonary vein antral isolation (PVAI). The location and extent of ablation that should be performed beyond PVAI for the m...

To the Editor: In their recent article, Durrie and colleagues1 reported results of lift-flap retreatment after LASIK. The authors concluded that this procedure appears to be effective and is associated with minimal complications. They reported that before reoperation, mean spherical equivalent refraction was -2.34 D (range, -0.67 to -5.75 D). The Summit Apex excimer laser (Summit Technology, Wa...

AIM To evaluate the usefulness of three-dimensional (3D) shear-wave elastography (SWE) in assessing the liver ablation volume after radiofrequency (RF) ablation. METHODS RF ablation was performed in vivo in 10 rat livers using a 15-gauge expandable RF needle. 3D SWE as well as B-mode ultrasound (US) were performed 15 min after ablation. The acquired 3D volume data were rendered as multislice ...

BACKGROUND Conventional catheter ablation of cavotricuspid isthmus (CTI)-dependent atrial flutter is a widely applied standard therapy. Remote magnetic catheter navigation (RMN) may provide benefits for different ablation procedures, but its efficacy for CTI ablation has not been evaluated in a randomized, controlled trial. METHODS AND RESULTS Ninety patients undergoing de novo ablation of at...

We performed a survey on current atrial fibrillation (AF) ablation techniques used for catheter ablation of AF among the European Heart Rhythm Association Research Network. The focus of this questionnaire is on the ablation strategy, such as the use of different lesion sets or sites of ablation in the various forms of AF, and on the technical aspects of catheter ablation with respect to energy ...

BACKGROUND Left atrial linear ablation for atrial fibrillation (AF) may be proarrhythmic, leading to left atrial macro-reentrant tachycardia (LAT). Whether due to failure to achieve block initially or to recovery of conduction after ablation is unknown. This study was designed to evaluate the frequency of recovery of mitral isthmus (MI) conduction compared with cavo-tricuspid isthmus (CTI) cond...

background: energy deficit is a common and serious problem in pediatric intensive care units. parenteral nutrition, either alone or in combination with enteral nutrition, can improve nutrient delivery in critically ill patients by preventing or correcting the energy deficit and improving the outcomes. intralipid 10% and 20% are lipid emulsions, widely used in parenteral nutrition. despite sever...

OBJECTIVE Remnant ablation with radioactive iodine (I-131) is a successful form of treatment that aims to destroy the remaining residual tissue and/or metastatic tissue after total thyroidectomy in differentiated thyroid cancer (DTC) patients. High level of thyroid stimulating hormone (TSH) (≥30 mIU/L) is recommended for success of ablation treatment. In this retrospective study, our aim was to...
