Outcomes in neonatal critical and non-critical aortic stenosis: a retrospective cohort study.

Objective: To compare long-term survival, reinterventions and risk factors using strict definitions of neonatal critical and non-critical valvular aortic stenosis (VAS).

Design: A nationwide retrospective study using data from patient files, echocardiograms and the Swedish National Population Registry.

Setting And Patients: All neonates in Sweden treated for isolated VAS 1994-2018.

Life satisfaction, health-related quality of life and physical activity after treatment for valvular aortic stenosis.

Objective: To investigate health-related quality of life and life satisfaction in children and adolescents treated for isolated congenital valvular aortic stenosis compared to healthy peers. Our second aim was to investigate the relationship between objectively measured physical activity, health-related quality of life and life satisfaction in the same group.

Methods: Forty-eight patients, 8-18 years of age, were recruited, as well as 43 healthy peers matched for age, gender and residential area.

Physical activity in children and adolescents with CHD: review from a measurement methodological perspective.

Aim: To compile a literature overview of physical activity in children with CHD and to critically evaluate the methodology used for physical activity assessment.

Methods: A review of the literature was performed using PubMed to identify studies examining accelerometer and subjectively assessed physical activity in children and adolescents with CHD.

Result: A total of 15 studies were included (6 studies using subjective measures and 9 articles using accelerometers for the assessment of physical activity).

Children and Adolescents Treated for Valvular Aortic Stenosis Have Different Physical Activity Patterns Compared to Healthy Controls: A Methodological Study in a National Cohort.

Previous research in children and adolescents with congenital heart defects presents contradictory findings concerning their physical activity (PA) level, due to methodological limitations in the PA assessment. The aim of the present cross-sectional study was to compare PA in children and adolescents treated for valvular aortic stenosis with healthy controls using an improved accelerometer method. Seven-day accelerometer data were collected from the hip in a national Swedish sample of 46 patients 6-18 years old treated for valvular aortic stenosis and 44 healthy controls matched for age, gender, geography, and measurement period.

Case Report: Disseminated Systemic Embolism of Lipiodol After Lymphography for Plastic Bronchitis After Fontan Repair.

Lipiodol-based lymphangiography is not only a diagnostic tool for visualization of lymphatic disorders such as plastic bronchitis (PB), but also aims a therapeutic effect by embolizing lymph leakages. We performed such percutaneous lymphatic embolization for PB in a Fontan patient with proven absence of right-to-left shunt, and demonstrated important lymphatic abnormalities in the mediastinum. Shortly after the procedure, the patient developed severe convulsive seizures, revealing multiple cerebral embolisms of Lipiodol.

A national study of the outcome after treatment of critical aortic stenosis in the neonate.

Objective: This study describes short-term and long-term outcome after treatment of critical valvular aortic stenosis in neonates in a national cohort, with surgical valvotomy as first choice intervention.

Methods: All neonates in Sweden treated for critical aortic stenosis between 1994 and 2016 were included. Patient files were analysed and cross-checked against the Swedish National Population Registry as of December 2017, giving complete survival data.

Treatment of valvular aortic stenosis in children: a 20-year experience in a single institution.

Objectives: This study presents short- and long-term follow-up after treatment for isolated valvular aortic stenosis in children with surgical valvotomy as the preferred 1st intervention.

Methods: All patients aged 0-18 years treated between 1994 and 2013 at our centre were reviewed regarding the mode of first treatment, mortality, reinterventions and the need for aortic valve replacement.

Results: A total of 113 patients were identified in local registries.
