Periprocedural complications after laser balloon ablation procedures for atrial fibrillation: An analysis using a nationwide claims database

Heart Rhythm O2
Background: Evidence regarding the periprocedural safety of laser balloon (LB) catheter ablation for atrial fibrillation (AF) is scarce. Objective: We aimed to investigate the periprocedural safety of LB ablation for AF compared with that of either ...

Radiofrequency Ablation in the Treatment of Liver Metastases of Colorectal Cancer

Acta Medica Martiniana, 2012
Many methods of minimally invasive therapy have been developed in recent years to eliminate tumours in organs like the liver. One of the most promising methods is called radiofrequency ablation, occasionally referred to as RFA. In radiofrequency ablation,

Radiofrequency Ablation of Cancer [PDF]

CardioVascular and Interventional Radiology, 2004
Radiofrequency ablation (RFA) has been used for over 18 years for treatment of nerve-related chronic pain and cardiac arrhythmias. In the last 10 years, technical developments have increased ablation volumes in a controllable, versatile, and relatively inexpensive manner. The host of clinical applications for RFA have similarly expanded.

Metamaterial Antennas Enhance MRI of the Eye and Occipital Brain

Advanced Materials, EarlyView.
A radiofrequency antenna platform comprising planar and bend configurations is developed, incorporating structurally integrated epsilon‐negative metamaterial unit cells to enhance MRI. These antennas enable high‐resolution in vivo human MRI of the eye, orbit, and occipital brain. Comprehensive validation, including simulations, phantom experiments, SAR,

LEAD: Literature Enhanced Ab Initio Discovery of Nitride Dusting Layers for Enhanced Tunnel Magnetoresistance and Lower Resistance Magnetic Tunnel Junctions

Advanced Materials, EarlyView.
Magnetic tunnel junctions (MTJs) using MgO tunnel barriers face challenges of high resistance‐area product and low tunnel magnetoresistance (TMR). To discover alternative materials, Literature Enhanced Ab initio Discovery (LEAD) is developed. The LEAD‐predicted materials are theoretically evaluated, showing that MTJs with dusting of ScN or TiN on ...

Transducers Across Scales and Frequencies: A System‐Level Framework for Multiphysics Integration and Co‐Design

Advanced Materials Technologies, EarlyView.
Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...

Effect of the Size of the Left Atriumo Sustained Sinus Rhythm in Patients Undergoing Mitral Valve Surgery and Concomitant Bipolar Radiofrequency Ablation for Atrial Fibrillation

Acta Clinica Croatica, 2017
Atrial fibrillation is associated with systemic embolization and complications due to anticoagulant therapy. Radiofrequency ablation has been established as an effective and safe method for the treatment of atrial fibrillation.
