Objective: The aim of this case report is to highlight the importance of excluding aortic coarctation in a patient with a bicuspid aortic valve.
Clinical Presentation And Intervention: A 56-year-old woman with hypertension was admitted complaining of progressive dyspnea. Transthoracic echocardiography showed a calcified, bicuspid aortic valve with severe stenosis. Aortography revealed the presence of severe narrowing of the aorta between the carotid and subclavian arteries. The patient was referred for cardiovascular surgery in which successful aortic valve replacement and aortic correction were performed.
Conclusion: This case report shows an uncommon finding of infantile aortic coarctation in an adult patient admitted with heart failure.

Clarifying the inceptive pathophysiology of hypertensive heart disease helps to impede the disease progression. Through coarctation of the infrarenal abdominal aorta (AA), we induced hypertension in minipigs and evaluated physiological reactions and morpho-functional changes of the heart. Moderate aortic coarctation was achieved with approximately 30 mmHg systolic pressure gradient in minipigs.

Background: Coarctation of the aorta (CoA) is a relatively common congenital heart defect. The underlying causes are not known, but a combination of genetic factors and abnormalities linked to embryonic development is suspected. There are only a few studies of the underlying molecular mechanisms in CoA.

Hybrid repair of complex aortic arch disease typically requires aortic debranching to create a proximal landing zone for completion arch endografting. Despite advances in endograft technology, physician-modified endografting may be required to customize a prosthesis for challenging anatomy. We present a case of a complex distal arch aneurysm after a prior coarctation repair with a pediatric interposition graft several decades earlier, treated with hybrid repair by double transposition for arch debranching and physician-modified arch endografting for complete aneurysm exclusion.

Purpose: To correct maternal breathing and fetal bulk motion during fetal 4D flow MRI.
Methods: A Doppler-ultrasound fetal cardiac-gated free-running 4D flow acquisition was corrected post hoc for maternal respiratory and fetal bulk motion in separate automated steps, with optional manual intervention to assess and limit fetal motion artifacts. Compressed-sensing reconstruction with a data outlier rejection algorithm was adapted from previous work.
