Pinning down the accuracy of physics-informed neural networks under laminar and turbulent-like aortic blood flow conditions.

Background: Physics-informed neural networks (PINNs) are increasingly being used to model cardiovascular blood flow. The accuracy of PINNs is dependent on flow complexity and could deteriorate in the presence of highly-dynamical blood flow conditions, but the extent of this relationship is currently unknown. Therefore, we investigated the accuracy and performance of PINNs under a range of blood flow conditions, from laminar to turbulent-like flows.

Immediate Use of Impella CP for High-Risk Percutaneous Coronary Intervention After Repair of Thrombosed Aortic Coarctation.

Aortic coarctation represents up to 7% of congenital heart diseases and is associated with hypertension and coronary artery disease, which continues to be the leading cause of death even after successful surgical repair. However, there is limited knowledge of managing both conditions, especially in the setting of an acute coronary syndrome. We herein present the case of a 53-year-old man with a history of hypertension who initially presented with an ST-elevation myocardial infarction successfully treated with thrombolysis and hemodynamic compromise.

A clinical perspective on surgical and diagnostic strategies for neonatal partial shone complex: Insights from a case report.

Introduction And Clinical Importance: Shone complex (SC) is a rare multilevel congenital heart disease (CHD) characterized by four left-sided heart obstructive lesions: parachute mitral valve, supravalvular mitral ring, subaortic stenosis, and coarctation of the aorta (CoA), accounting for 0.6-0.7 % of CHD cases.

The global effect of aortic coarctation on carotid and renal pulsatile hemodynamics.

Coarctation of the aorta (CoA) is a congenital disease characterized by the narrowing of the aorta, typically the descending portion after the left subclavian artery. If left untreated, by the time individuals reach 50 years of age, the mortality rate can reach 90%. Previous studies have highlighted the adverse effects of CoA on local hemodynamics.

Can we diagnose aortic arch obstruction in a fetus with an atrioventricular septal defect?

Background: Aortic arch obstruction and/or coarctation of aorta is uncommon (5-20%) in balanced atrioventricular septal defects. Although technically challenging, prenatal diagnosis of aortic arch obstruction in atrioventricular septal defect is critical for delivery planning and improves prenatal counselling regarding the timing of cardiac surgery. We sought to identify prenatal predictors of coarctation of aorta in atrioventricular septal defect.

Differences between echocardiography and cardiac nuclear magnetic resonance parameters in children with bicuspid aortic valve-related aortopathy.

Objectives: The bicuspid aortic valve (BAV) is the most common congenital heart defect. Patients with BAV frequently develop aortopathy, which depends on the dysfunction and morphotype of the BAV.

Aim: The aim of our study was to compare the echocardiography and cardiac magnetic resonance (CMR) findings in BAV patients, and to define the risks of BAV dysfunction and aortopathy.

Evaluation of Postnatal Echocardiographic Screening for Congenital Heart Defects - a Prospective Cohort Study at a German University Hospital.

Background: Congenital heart defects (CHD) being the most common congenital malformation, significantly impact mortality and morbidity in children and adults. Early detection greatly improves treatment and prognosis. Routine pulse oximetry screening and fetal echocardiography in Germany have advanced early CHD diagnosis.

Role of stimulated by retinoic acid 6 in 46 children of coarctation of the aorta.

(1) ObjectiveCoarctation of the aorta (CoA) is a complex congenital heart disease. Research on differential genes in patients with CoA and other groups of aortas and investigating the pathogenesis of aorta coarctation is essential for prevention and diagnosis. This study was conducted between January 2019 and December 2021.
