Noninvasive Assessment of Atrial Fibrillation Complexity in Relation to Ablation Characteristics and Outcome

Frontiers in Physiology, 2018
Background: The use of surface recordings to assess atrial fibrillation (AF) complexity is still limited in clinical practice. We propose a noninvasive tool to quantify AF complexity from body surface potential maps (BSPMs) that could be used to choose ...

O-12 CHARACTERIZATION AND UTILIZATION OF HCV-POSITIVE DONORS IN ARGENTINA

Annals of Hepatology, 2023
Introduction and Objectives: Increased utilization of hepatitis C virus (HCV)-positive organ donors has been endorsed as one of several ways to combat organ shortages. However, HCV-positive donors remain poorly characterized. This study aimed to evaluate

WEAR TESTING MACHINE BY LASER BEAM ABLATION PATENT NO 24013 EGYPTIAN PATENT OFFICE [PDF]

Proceedings on Engineering Sciences, 2019
Wear testing machine by laser ablation has been considered as a new method of wear testing which overcome the problems of old machines and systems. In this case, wear rate has occurred due to ablation by laser beam and test sample transformed from solid ...

Picosecond Laser Ablation of Polyhydroxyalkanoates (PHAs): Comparative Study of Neat and Blended Material Response [PDF]

, 2019
Polyhydroxyalkanoates (PHAs) have emerged as a promising biodegradable and biocompatible material for scaffold manufacturing in the tissue engineering field and food packaging. Surface modification is usually required to improve cell biocompatibility and/

Atrial fibrillation ablation with a spring sensor-irrigated contact force-sensing catheter compared with other ablation catheters: systematic literature review and meta-analysis

BMJ Open, 2019
ObjectivesThe objective of our review was to systematically assess available evidence on the effectiveness, safety and efficiency of a spring sensor-irrigated contact force (CF) catheter (THERMOCOOL SMARTTOUCH Catheter (ST)) for percutaneous ablation of ...

Toward Mechanism-Directed Electrophenotype-Based Treatments for Atrial Fibrillation

Frontiers in Physiology, 2020
Current treatment approaches for persistent atrial fibrillation (AF) have a ceiling of success of around 50%. This is despite 15 years of developing adjunctive ablation strategies in addition to pulmonary vein isolation to target the underlying ...

Ablation in Externally Applied Electric and Magnetic Fields

Nanomaterials, 2020
To harness light-matter interactions at the nano-/micro-scale, better tools for control must be developed. Here, it is shown that by applying an external electric and/or magnetic field, ablation of Si and glass under ultra-short (sub-1 ps) laser pulse ...

Classification of Fibrillation Organisation Using Electrocardiograms to Guide Mechanism-Directed Treatments

Frontiers in Physiology, 2021
Background: Atrial fibrillation (AF) and ventricular fibrillation (VF) are complex heart rhythm disorders and may be sustained by distinct electrophysiological mechanisms. Disorganised self-perpetuating multiple-wavelets and organised rotational drivers (
