The prevalence of underweight and obesity in CHD. Response to body mass index and age are associated with ventricular end-diastolic pressure in adults with a Fontan circulation.

Introduction: The aim of the study is to determine the impact of obesity in children with CHD which is severe enough to require invasive catheterisation.

Methodology: This is a retrospective study in a cardiac catheterisation laboratory of a large paediatric hospital. The material consisted of 378 children from 2 to 19 years old who underwent heart catheterisation in the years 2011-2019.

Duct stenting in an ELBW infant with aortic arch interruption.

Aortic arch interruption is a rare cardiac malformation. In some cases, it is part of a more complex congenital heart disease. Survival of extremely low birth weight infants with this cardiac disease is very rare.

Recurrent arterial ischemic strokes in a patient with patent foramen ovale and ductus arteriosus: Presentation of our management and review of the literature.

Ischemic stroke in children is a relatively rare entity, relative to the adult population. The most common potential risk factors include cardiac embolism, prothrombotic states and vasculopathies. The diagnosis is concerning for the need to identify the underlying cause.

Cerebral hemorrhagic infarction as the initial manifestation of deep venous thrombosis in a child with patent foramen ovale.

Arterial ischemic stroke (AIS), with an estimated incidence of 1.1-4.3 per 100,000, is an important cause of morbidity and mortality in children and the risk of recurrence is high.

Transcatheter closure of large atrial septal defects with deficient aortic or posterior rims using the "Greek maneuver". A multicenter study.

Objectives: We report a modification ("Greek maneuver") of the standard atrial septal defect (ASD) closure technique using the Amplatzer septal occluder (ASO) to facilitate closure of large ASDs with deficient aortic or posterior rims.

Methods: 185 patients (median 10.8, range 3 to 52 years) with large ASDs (mean diameter 26±7 mm, range 20-40 mm) with a deficient aortic (134 patients) or posterior (51 patients) rim underwent catheter closure with the ASO using the "Greek maneuver" under transesophageal guidance.
