Fetal heterotaxy with tricuspid atresia, pulmonary atresia, and isomerism of the right atrial appendages at 22 weeks. [PDF]

open access: yes, 2013
We report the accurate prenatal diagnosis at 22 weeks gestation of right atrial isomerism in association with tricuspid atresia. Several distinctive sonographic features of isomerism of the right atrial appendages were present in this fetus: complex ...

Soft Beats: A Dielectric Elastomer‐Based Ventricular Assist Device for Next‐Gen Heart Failure Management

open access: yesAdvanced Engineering Materials, EarlyView.
The dielectric elastomer‐based electropneumatic device (DE‐EPD) is a vacuum‐assisted ventricular assist device (VAD) that delivers high performance (85 mmHg, 6.8 L min−1) with low power consumption. Unlike traditional motor‐driven VADs, it is lightweight, quiet, energy‐efficient, and provides pulsatile flow. Validated in a simulated circulation system,

Association of Thoracic Aorta Calcium Score With Exercise Blood Pressure Response and Clinical Outcomes in Elderly Individuals: Differential Impact of Aorta Calcification Compared With Coronary Artery Calcification

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2016
BackgroundThe structure of the aorta is considered to influence exercise systolic blood pressure (SBP) response, which, in turn, might impact upon adverse outcomes.

Spontaneous subarachnoid haemorrhage due to coarctation of aorta and intraspinal collaterals : a rare presentation [PDF]

open access: yes, 2012
The occurrence of spontaneous subarachnoid haemorrhage (SAH) in association with coarctation of thoracic aorta and absence of intracranial aneurysm is a rare association.

Alleviation of Aging‐Related Hallmarks in a Mouse Model of Progeria via a Nanoparticle‐Based Artificial Transcription Factor

open access: yesAdvanced Functional Materials, EarlyView.
Oct4‐nanoscript, a biomimetic nanoparticle‐based artificial transcription factor, precisely regulates cellular rejuvenation by activating Oct4 target genes, restoring epigenetic marks, and reducing DNA damage. In a progeria model, it effectively rescued aging‐associated pathologies and extended lifespan.

Differential sensitivity of basal and acetylcholine-induced activity of nitric oxide to blockade by asymmetric dimethylarginine (ADMA) in the rat aorta [PDF]

open access: yes, 2010
<b>Background and purpose</b>: Previous work has shown that NG-monomethyl-l-arginine (l-NMMA) paradoxically inhibits basal, but not ACh-stimulated activity of nitric oxide in rat aorta.

3D (Bio) Printing Combined Fiber Fabrication Methods for Tissue Engineering Applications: Possibilities and Limitations

open access: yesAdvanced Functional Materials, EarlyView.
Biofabrication aims at providing innovative technologies and tools for the fabrication of tissue‐like constructs for tissue engineering and regenerative medicine applications. By integrating multiple biofabrication technologies, such as 3D (bio) printing with fiber fabrication methods, it would be more realistic to reconstruct native tissue's ...

Dacron graft aneurysm with dissection

open access: yesIndian Journal of Radiology and Imaging, 2016
Dacron grafts have been used as a conduit for large caliber arteries for many years successfully. However, these grafts can undergo complications such as aneurysm formation, rupture, and failure.

COARCTATION OF THE AORTA [PDF]

open access: yesHeart, 1947
Coarctation of the aorta was first described by Morgagni in 1760, and in its simplest form refers to isolated and discrete stenosis of the proximal thoracic aorta. However, coarctation may also be associated with a longer segment of narrowing, with hypoplasia of the transverse aortic arch, or with stenosis of the lower thoracic or abdominal aorta (Ho ...

Embedded 3D‐Coaxial Bioprinting of Stenotic Brain Vessels with a Mechanically Enhanced Extracellular Matrix Bioink for Investigating Hemodynamic Force‐Induced Endothelial Responses

open access: yesAdvanced Functional Materials, EarlyView.
In this study, a physically enhanced vascular dECM bioink and used 3D‐coaxial bioprinting are developed to fabricate mature brain blood vessels for cerebral atherosclerosis research. This model demonstrates that vascular geometry‐induced hemodynamic changes trigger vascular inflammation, ensuring its potential for cerebrovascular research.
