Tratamiento híbrido en dos tiempos de síndrome aórtico agudo tipo A asociado a coartación de aorta y válvula aórtica bicúspide

Cirugía Cardiovascular, 2022
Resumen: La coartación aórtica puede aparecer aislada o asociada a otras lesiones. La asociación más frecuente es la válvula aórtica bicúspide, que no suele ser problemática a corto-medio plazo, pero se asocia tardíamente a complicaciones en la aorta ...

Miniaturized Devices for On‐the‐Spot Generation of Small‐Diameter Vascular Grafts

Advanced Materials Technologies, EarlyView.
An intracorporeal extrusion device is developed for on‐the‐spot generation of vascular grafts with tunable diameters spanning from 1 to 6 mm. The device uses biomimetic polymers and light, to promptly obtaining biocompatible and high‐burst pressure‐resistant grafts.

A Novel Protein NAB1‐356 Encoded by circRNA circNAB1 Mitigates Atrial Fibrillation by Reducing Inflammation and Fibrosis

Advanced Science, EarlyView.
The circRNA circNAB1 is downregulated in AF patient. Silencing circNAB1 promotes collagen deposition and inflammation, whereas overexpression reduces AF susceptibility. circNAB1 encodes the protein NAB1 356 that interacts with EGR1 to mitigate fibrosis and inflammation.

A deep learning approach to using wearable seismocardiography (SCG) for diagnosing aortic valve stenosis and predicting aortic hemodynamics obtained by 4D flow MRI [PDF]

arXiv, 2023
In this paper, we explored the use of deep learning for the prediction of aortic flow metrics obtained using 4D flow MRI using wearable seismocardiography (SCG) devices. 4D flow MRI provides a comprehensive assessment of cardiovascular hemodynamics, but it is costly and time-consuming.

P21‐Activated Kinase 2 as a Novel Target for Ventricular Tachyarrhythmias Associated with Cardiac Adrenergic Stress and Hypertrophy

Advanced Science, EarlyView.
Ca2+/calmodulin‐dependent kinase II (CaMKII) activation is likely driven by oxidative stress, particularly excessive reactive oxygen species (ROS) production. This study identifies P21‐activated kinase 2 (Pak2) as a novel regulator of ROS‐induced CaMKII activation and abnormal Ca2⁺ dynamics in acute adrenergic and chronic pressure‐overload stressed ...

Automatic Aortic Valve Pathology Detection from 3-Chamber Cine MRI with Spatio-Temporal Attention Maps [PDF]

arXiv, 2023
The assessment of aortic valve pathology using magnetic resonance imaging (MRI) typically relies on blood velocity estimates acquired using phase contrast (PC) MRI. However, abnormalities in blood flow through the aortic valve often manifest by the dephasing of blood signal in gated balanced steady-state free precession (bSSFP) scans (Cine MRI).

Syntaxin 17 Translocation Mediated Mitophagy Switching Drives Hyperglycemia‐Induced Vascular Injury

Advanced Science, EarlyView.
Mitophagy switching drives high‐glucose‐induced vascular endothelial injury. Short‐term high‐glucose exposure upregulates Fis1 expression and enhances Fis1‐TBC1D15 interaction, activating Parkin‐mediated mitophagy. Long‐term high‐glucose exposure reduces Fis1 expression, inhibiting Parkin‐mediated mitophagy and triggering mitophagy switching from ...
