AIMS The natural history of congenital or childhood non-immune, isolated atrioventricular (AV) block is poorly defined. METHODS AND RESULTS We retrospectively studied 141 children with isolated, non-immune AV block diagnosed in utero, or up to 15 years of age, at 13 French medical centres, between 1980 and 2009. Patients with structural heart disease or(More)
BACKGROUND The origin of congenital or childhood nonimmune isolated atrioventricular (AV) block remains unknown. We hypothesized that this conduction abnormality in the young may be a heritable disease. METHODS AND RESULTS A multicenter retrospective study (13 French referral centers, from 1980-2009) included 141 children with AV block diagnosed in utero,(More)
BACKGROUND Morbidity and mortality are higher for cardiac reoperations than first operation due to the presence of post-operative adhesions. We retrospectively evaluated the efficacy of the bioresorbable membrane Seprafilm to prevent pericardial adhesions after cardiac surgery in a paediatric congenital heart disease population. METHODS Seventy-one(More)
An arteriovenous malformation of the vein of Galen was diagnosed using two-dimensional ultrasound and pulsed Doppler method, in a neonate with congestive heart failure. Contrast echocardiography showed right to left atrial and ductal shunting. Sector scans of the brain revealed an echo free intracranial mass with venous flow at the Doppler. Doppler(More)
Background The term " malposition of great arteries " is commonly used for diagnosis and surgery in abnormal ventriculo-arterial connections with usual arrangement and two well developed ventricles. In these abnormalities the variability of the arterial relationships is considerable and all relationships from normal to side by side to antero posterior have(More)
