Impact of an Impaired Maternal-Fetal Environment on Death in Children With Congenital Heart Defects Undergoing Surgery in Denmark From 1994 to 2018.

Background: Studies show that an impaired maternal-fetal environment (iMFE) increases the mortality risk in children with single-ventricle congenital heart defects (CHDs). We investigated the impact of an iMFE on death in children with various surgically corrected CHDs.

Methods And Results: In this nationwide register-based study, we examined the association between an iMFE (including preeclampsia, gestational hypertension, gestational diabetes, maternal smoking during pregnancy) and death in a large cohort of children with surgically corrected CHDs in Denmark (1994-2018).

Altered Cerebral Microstructure in Adults With Atrial Septal Defect and Ventricular Septal Defect Repaired in Childhood.

Background Delayed brain development, brain injury, and neurodevelopmental disabilities are commonly observed in infants operated for complex congenital heart defect. Our previous findings of poorer neurodevelopmental outcomes in individuals operated for simple congenital heart defects calls for further etiological clarification. Hence, we examined the microstructural tissue composition in cerebral cortex and subcortical structures in comparison to healthy controls and whether differences were associated with neurodevelopmental outcomes.

Renal Artery Stenting in Consecutive High-Risk Patients With Atherosclerotic Renovascular Disease: A Prospective 2-Center Cohort Study.

Background The aim of this study was to prospectively evaluate the effects of renal artery stenting in consecutive patients with severe atherosclerotic renal artery stenosis and high-risk clinical presentations as defined in a national protocol developed in 2015. Methods and Results Since the protocol was initiated, 102 patients have been referred for revascularization according to the following high-risk criteria: severe renal artery stenosis (≥70%) with true resistant hypertension, rapidly declining kidney function, or recurrent heart failure/sudden pulmonary edema. At baseline, the mean 24-hour ambulatory systolic blood pressure was 166.
