We report three cases of transient myocardial hypertrophy, diagnosed by echocardiography, occurring between the second and seventh days of life in neonates with initially normal ventricular myocardial wall thickness. The three term neonates had perinatal injury with acute fetal distress. In all three cases electrocardiographic and biologic signs of(More)
BACKGROUND Percutaneous closure of large persistent ductus arteriosus using the Amplatzer duct occluder is an alternative to surgery. However, this device is not recommended in infants weighing less than 6 kg. AIM To evaluate the safety and effectiveness of this procedure in low-body-weight infants. METHODS We reviewed retrospectively data for infants(More)
Transcatheter closure of atrial septal defect (ASD) in children is now an accepted treatment as an alternative to surgery. We report a case of complete atrioventricular block (AVB) observed over several days after closure of an ASD with an Amplatzer Septal Occluder(®) in a 13-year-old child. The spontaneous outcome was good with regression of the complete(More)
Donohue syndrome or leprechaunism is a severe congenital insulin-resistance syndrome. It is characterized by intra-uterine and neonatal growth retardation, typical dysmorphic features, and metabolic abnormalities with hyperinsulinism and hyperandrogenism. Problems in energy metabolism and loss of glucose homeostasis are responsible for early death in the(More)
Heart murmurs are common in children and adolescents. Although most are innocent, an isolated heart murmur in asymptomatic children may be the sole finding indicating serious heart disease. Historical elements of familial heart disease, cardiovascular symptoms and a well-conducted medical examination can identify children with an increased risk of heart(More)
Intraoperative Doppler sonographic examinations were carried out on seven preterm neonates to measure cerebral blood flow velocity changes in the anterior cerebral arteries during ductus arteriosus ligation. Age at surgery was 12±6 days. Continuous recordings during the operative procedure showed a rapid increase in diastolic blood pressure (P<0.01),(More)
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)
The authors describe the measurement of cardiac output by Doppler echocardiography in neonates and infants. After reviewing theoretical considerations, the authors review the various practical aspects of the method. They emphasize the need for an excellent technique so that possible errors are avoided. In their experience, the most appropriate measurement(More)
