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

open access: yesJournal 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

Zero‐Fluoroscopy Ablation Methods for Atrial Fibrillation: A Systematic Review and Meta‐Analysis

open access: yesPacing and Clinical Electrophysiology, EarlyView.
Central illustration. Schematic comparison of conventional fluoroscopy guided ablation (left) and zero fluoroscopy ablation (right), enabled by electroanatomical mapping and intracardiac echocardiography for catheter navigation without X ray. The study selection process is summarized (133 records identified; 12 studies included, total n = 1998 ...

Pulmonary arterial hypertension caused by compression of the left lower pulmonary vein in children

open access: yesJournal of Cardiothoracic Surgery
Objectives To investigate, through four clinical cases, whether compression-induced deformation of the left lower pulmonary vein by the descending aorta is an etiological factor in certain cases of severe pulmonary arterial hypertension (PAH) in children.

Navigating the Zero Fluoroscopy Frontier: Current Tools, Evidence and Future Directions in Electrophysiology Procedures

open access: yesPacing and Clinical Electrophysiology, EarlyView.
Graphical Abstract ABSTRACT Fluoroscopy has traditionally been the mainstay imaging technique for guidance during electrophysiology (EP) ablation procedures. The numerous disadvantages associated with radiation exposure for both operators and patients have created the need for zero‐fluoroscopy (ZF) approaches. Today, electrophysiologists have access to

Case Report: Successful primary sutureless repair of common pulmonary vein atresia in a neonate

open access: yesFrontiers in Pediatrics
Common pulmonary vein atresia (CPVA) is an extremely rare and lethal congenital heart defect characterized by the absence of a functional connection between the common pulmonary vein chamber (CPVC) and both the left atrium and systemic venous system.

Rising Comorbidity Burden in Inpatient Atrial Fibrillation Catheter Ablation: Temporal Trends and In‐Hospital Outcomes

open access: yesPacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Background Despite advancements in catheter ablation (CA) technique and expertise, success rates of atrial fibrillation (AF) ablation have not substantially improved in recent years. Treating patients with advanced age and higher comorbidities may limit success rates while increasing complications.

Understanding extracellular vesicles in antiaging

open access: yesPeriodontology 2000, EarlyView.
Abstract Background Aging is a multifactorial process marked by gradual cellular dysregulation, regulated by hallmarks, including genomic instability, mitochondrial dysregulation, and chronic inflammation. Extracellular vesicles (EVs), especially exosomes, have emerged as pivotal mediators of cell‐to‐cell communication with potential roles in both ...
