Characterization of AF Recurrence and Substrate Health by Electrographic Flow (EGF) Consistency in EGF Mapping

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background Electrographic flow (EGF) mapping is an FDA 510(k)‐cleared method for visualizing atrial activation wavefronts in atrial fibrillation (AF). Its clinical efficacy in detecting AF sources was demonstrated in the FLOW‐AF randomized controlled trial, and the underlying machine learning strategy used to develop and refine EGF source ...

Anatomical Determinants of the Left Atrial Electrograms: Wall Thickness and Myocardial Fat Infiltration

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Introduction Electrogram peak‐to‐peak voltage depends on atrial wall structure and mapping configuration. We evaluated the relationship between computed tomography–derived atrial wall thickness, intramyocardial fat, myocardial muscle thickness, and electrogram voltage obtained with omnipolar, bipolar, and unipolar mapping.

Omnipolar Technology Near Field Versus Fragmentation Signals Mapping at Anatomically Defined Ganglionated Plexi Sites During Cardioneuroablation

Journal of Cardiovascular Electrophysiology, EarlyView.
Omnipolar Technology Near Field versus fragmentation signals mapping at anatomically defined ganglionated plexi sites during cardioneuroablation. The procedural workflow (left) guides patient selection through real‐time GP detection, biatrial ablation, and acute endpoint assessment, yielding 81% syncope‐free survival at 20 months.

Hyperspectral tomographic diffractive microscopy: Development and applications

Journal of Microscopy, EarlyView.
Abstract Tomographic Diffractive Microscopy (TDM) provides label‐free three‐dimensional imaging of transparent samples with resolution surpassing confocal limits. At IRIMAS, successive instrumental developments since 2009 have enhanced TDM capabilities through transmission, reflection, isotropic, polarisation‐sensitive, and dual‐view configurations ...

Beyond single cells: Ten years of commercial lattice light‐sheet microscopy

Journal of Microscopy, EarlyView.
Abstract Lattice light‐sheet microscopy (LLSM) enables gentle, rapid, volumetric fluorescence imaging of living biological systems. The technique employs Bessel beam interference to produce a light‐sheet which retains its thickness over a relatively large field‐of‐view compared to other light‐sheets.
