Comparison of 2D and 4D Flow MRI in Neonates Without General Anesthesia

Journal of Magnetic Resonance Imaging, Volume 57, Issue 1, Page 71-82, January 2023., 2023
Background Neonates with critical congenital heart disease require early intervention. Four‐dimensional (4D) flow may facilitate surgical planning and improve outcome, but accuracy and precision in neonates are unknown. Purpose To 1) validate two‐dimensional (2D) and 4D flow MRI in a phantom and investigate the effect of spatial and temporal resolution;

Acute anterior wall myocardial infraction in asymptomatic severe aortic Coarctation in young adult – A rare case

Indian Heart Journal, 2016
Coarctation of Aorta is not rare in general population. Aortic Coarctation represents about 5–8% of all congenital cardiac diseases, and it is commonly associated with bicuspid aortic valve.

Impact of Turbulence Modeling on the Simulation of Blood Flow in Aortic Coarctation [PDF]

arXiv, 2022
Numerical simulations of pulsatile blood flow in an aortic coarctation require the use of turbulence modeling. This paper considers three models from the class of large eddy simulation (LES) models (Smagorinsky, Vreman, $\boldsymbol{\sigma}$-model) and one model from the class of variational multiscale models (residual-based) within a finite element ...

Simultaneous correction of aortic coarctation and bicuspid aortic valve in an adult patient (case report)

Український журнал серцево-судинної хірургії, 2019
Aortic coarctation is one of the most frequent congenital heart defects; the frequency is in the range of 6-7%. Aortic coarctation is often associated with other heart defects, namely: a bicuspid aortic valve, an interventricular septal defect, and ...

Machine Learning based Extraction of Boundary Conditions from Doppler Echo Images for Patient Specific Coarctation of the Aorta: Computational Fluid Dynamics Study [PDF]

arXiv, 2022
Purpose- Coarctation of the Aorta (CoA) patient-specific computational fluid dynamics (CFD) studies in resource constrained settings are limited by the available imaging modalities for geometry and velocity data acquisition. Doppler echocardiography has been seen as a suitable velocity acquisition modality due to its higher availability and safety ...

Copy number variations analysis in a cohort of 47 fetuses and newborns with congenital diaphragmatic hernia

Prenatal Diagnosis, Volume 42, Issue 13, Page 1627-1635, December 2022., 2022
Abstract Objectives The congenital diaphragmatic hernia (CDH), characterized by malformation of the diaphragm and lung hypoplasia, is a common and severe birth defect that affects around 1 in 4000 live births. However, the etiology of most cases of CDH remains unclear.

In Silico Modelling of Aortic Strain and Strain Rate in Aortic Coarctation Treated with Stent Angioplasty with Comparison to Clinical Cohorts

Applications in Engineering Science, 2022
: Objective: Treatment of aortic coarctation has seen a shift from traditional surgical repair to the use of aortic stents. The aim of this study was to assess the impact upon hemodynamics and arterial strain when aortic coarctation is treated with a ...

Internal mammary artery dilatation in a patient with aortic coarctation, aortic stenosis, and coronary disease. Case report

Journal of Cardiothoracic Surgery, 2011
The ideal surgical approach is unclear in adult patients with coarctation of the aorta that is associated with other cardiovascular pathologies that require intervention. Standard median sternotomy allows simultaneous, coronary revascularization surgery,

Ascending to descending aortic prosthesis with reimplantation of brachiocephalic vessels in aneurysm of the arch and descending aorta for hypoplasia of the arch and coarctation of the aorta [PDF]

Кардіохірургія та інтервенційна кардіологія, 2020
Thoracic aortic aneurysm is one of the most serious pathologies of cardiovascular surgery. Occurrence of an aneurysm in the proximal or distal part of the aortic arch is a recognized complication of uncorrected aortic coarctation and is associated with a

Material transport in the left ventricle with aortic valve regurgitation [PDF]

Physical Review Fluids, 3(11), 113101 (2018), 2018
This experimental in vitro work investigates material transport properties in a model left ventricle in the case of aortic regurgitation, a valvular disease characterized by a leaking aortic valve and consequently double-jet filling within the elastic left ventricular geometry.
