The prevalence of genetic diagnoses in fetuses with severe congenital heart defects

open access: yesGenetics in Medicine, 2020
Purpose Congenital heart defects (CHD) are associated with genetic syndromes. Rapid aneuploidy testing and chromosome microarray analysis (CMA) are standard care in fetal CHD. Many genetic syndromes remain undetected with these tests.

Slc2a10 knock-out mice deficient in ascorbic acid synthesis recapitulate aspects of arterial tortuosity syndrome and display mitochondrial respiration defects

open access: yes, 2020
Arterial tortuosity syndrome (ATS) is a recessively inherited connective tissue disorder, mainly characterized by tortuosity and aneurysm formation of the major arteries.

Human gene copy number spectra analysis in congenital heart malformations [PDF]

open access: yes, 2012
The clinical significance of copy number variants (CNVs) in congenital heart disease (CHD) continues to be a challenge. Although CNVs including genes can confer disease risk, relationships between gene dosage and phenotype are still being defined.

Effects of stenotic aortic valve on the left heart hemodynamics: a fluid-structure-electrophysiology approach [PDF]

open access: yesarXiv, 2021
The aortic valve is a three-leaflet passive structure that, driven by pressure differences between the left ventricle and the aorta, opens and closes during the heartbeat to ensure the correct stream direction and flow rate. In elderly individuals or because of particular pathologies, the valve leaflets can stiffen thus impairing the valve functioning ...

Hybrid treatment of penetrating aortic ulcer*

open access: yesRadiologia Brasileira, 2015
Penetrating atherosclerotic aortic ulcer is a rare entity with poor prognosis in the setting of acute aortic syndrome. In the literature, cases like the present one, located in the aortic arch, starting with chest pain and evolving with dysphonia, are ...

Wall shear stress and pressure patterns in aortic stenosis patients with and without aortic dilation captured by high-performance image-based computational fluid dynamics [PDF]

open access: yesarXiv, 2022
Spatial patterns of elevated wall shear stress and pressure due to blood flow past aortic stenosis (AS) are studied using GPU-accelerated patient-specific computational fluid dynamics. Three cases of moderate AS, one with a dilated ascending aorta and two within the normal range (root diameter less than 4cm) are simulated for physiological beat cycle ...

ConvNet-Based Localization of Anatomical Structures in 3D Medical Images [PDF]

open access: yesIEEE Transactions on Medical Imaging , vol.PP, no.99, pp.1-1 (2017), 2017
Localization of anatomical structures is a prerequisite for many tasks in medical image analysis. We propose a method for automatic localization of one or more anatomical structures in 3D medical images through detection of their presence in 2D image slices using a convolutional neural network (ConvNet). A single ConvNet is trained to detect presence

Automatic Segmentation of Thoracic Aorta Segments in Low-Dose Chest CT [PDF]

open access: yesSPIE Medical Imaging, 2018, vol. 10574, pp. 105741S, 2018
Morphological analysis and identification of pathologies in the aorta are important for cardiovascular diagnosis and risk assessment in patients. Manual annotation is time-consuming and cumbersome in CT scans acquired without contrast enhancement and with low radiation dose.
