Validation of 3D echocardiographic volume detection of left atrium by human cadaveric casts

open access: yesBMC Medical Imaging, 2018
Background Left atrial volume is a prognostic factor in cardiac pathologies. We aimed to validate left atrial volume detection with 3D and 2D echocardiography (3DE and 2DE) by human cadaveric casts.

Presence of atrial natriuretic factor prohormone in enterochromaffin cells of the human large intestine [PDF]

open access: yes, 1991
Atrial natriuretic factor is a hormone intimately involved in water and salt homeostasis. The heart constitutes the major but not exclusive site of synthesis of this hormone.

A Spatiotemporal Single‐Cell Atlas Uncovers Dysregulated ECM Dynamics and Septal Remodeling Arrest in Human Ventricular Septal Defects

open access: yesAdvanced Science, EarlyView.
Integrating single‐cell and spatial transcriptomics reveals human ventricular septal defect (VSD) as a disease of microenvironmental insufficiency and structural remodeling arrest. Attenuated endothelial‐fibroblast crosstalk, alongside downregulated THBS1/TGF‐β1 and MMP2 signaling networks, impairs the endothelial‐to‐mesenchymal transition (EndoMT) and

Engineering a Bioelectronic Hybrid Heart with Integrated Sensing and Electrical Modulation

open access: yesAdvanced Science, EarlyView.
A bioelectronic hybrid heart is engineered by integrating iPSC‐derived cardiomyocytes, a decellularized cardiac scaffold, a cell‐laden ECM coating, and a flexible electronic mesh. The embedded electrodes enable real‐time recording of spontaneous electrical activity and localized stimulation, allowing controlled pacing and modulation of activation ...

Left Atrial ReModeling in Disease: Association with Clinical Markers

open access: yesJournal of the Indian Academy of Echocardiography & Cardiovascular Imaging, 2020
Background: The role of left atrial (LA) enlargement has a significant and independent association with moderate and severe diastolic dysfunction, atrial fibrillation, and left ventricular (LV) end-diastolic volume.

Left Atrial Appendage Closure Devices

open access: yes, 2014
Atrial fibrillation (AF) increases the risk for thromboembolic stroke five-fold. The left atrial appendage (LAA) has been shown to be the main source of thrombus formation in the majority of strokes associated with AF.

Stroke‐Heart Syndrome: Mechanisms, Temporal Phenotypes, and Diagnostic Reasoning

open access: yesAdvanced Science, EarlyView.
Stroke‐heart syndrome describes new or worsened cardiac abnormalities after acute stroke. This Review defines its clinical boundaries, traces autonomic, inflammatory, endothelial, and supply‐demand mechanisms across time, and proposes provisional phenotypes that integrate lesion location, premorbid cardiac substrate, serial biomarkers ...
