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.

Learning Curve of Pentaspline Pulsed‐Field Ablation With Posterior Wall Isolation for Persistent Atrial Fibrillation

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background Pentaspline pulsed‐field ablation (PFA) has emerged as a novel modality for pulmonary vein isolation (PVI) and posterior wall isolation (PWI) in persistent atrial fibrillation (AF). However, the learning curve associated with combined PVI + PWI and the contribution of anatomical factors to acute lesion completeness remain ...

Development and Validation of a Novel Contact Force‐Integrated Pulsed Field Quantization Index for Pulmonary Vein Isolation in a Porcine Model

Journal of Cardiovascular Electrophysiology, EarlyView.
A two‐phase pre‐clinical porcine study was performed to develop and validate the Pulsed Field Quantisation Index (PFQI), the first bipolar‐specific ablation index integrating real‐time contact force (CF), pulse‐train number, delivery voltage, and impedance variation for bipolar pulsed field ablation (PFA).

Random forest segmentation and spatial analysis of injected cardiac spheroids in optically cleared myocardium

Journal of Microscopy, EarlyView.
Abstract Accurate quantification of transplanted cardiac spheroids requires three‐dimensional (3D) localisation within intact myocardium, yet this remains technically challenging. Optical clearing and light‐sheet microscopy enable volumetric imaging of injection sites, but automated segmentation is difficult when transplanted spheroids and host tissue ...

Human cerebral arterial morphogenesis explored by 3D microscopic imaging of cleared embryos: Bridging the gap between embryonic and adult anatomy

Journal of Anatomy, EarlyView.
We provide a description of human embryonic cerebral arterial development based on whole‐mount immunostaining, tissue clearing, three‐dimensional (3D) light‐sheet microscopy imaging, and anatomically informed virtual segmentation of human embryos. Findings are compared with adult radiological anatomy. We provide a detailed account of the development of
