BACKGROUND Valved conduits from the right ventricle to the pulmonary artery are frequently used in paediatric cardiac surgery. However, stenosis and insufficiency of the conduit usually occur in the follow-up and lead to reoperations. Conduit stenting can delay surgical replacement, but it aggravates pulmonary insufficiency. We developed an innovative(More)
BACKGROUND Three-dimensional echocardiography (3DE) allows accurate calculation of ventricular volumes despite a remaining geometric assumption on the ventricular shape. Few studies involving full volume reconstruction software have been performed on children. Our aim was to compare the left ventricular (LV) volume measurements obtained with the most used(More)
OBJECTIVE To investigate the feasibility of using real-time three-dimensional echocardiography (3DE) to evaluate the fetal heart. METHODS Sixty fetuses were studied with gestational age between 22 and 34 weeks. The fetal heart was normal in 44 fetuses. In 16 fetuses, the fetal heart had morphologic abnormalities (hypoplastic left ventricle in 4, tetralogy(More)
UNLABELLED Abnormalities of norepinephrine uptake have been found to reflect impairment of cardiac adrenergic neuronal function in adults with heart failure. To our knowledge, no data on childhood dilated cardiomyopathy (DCM) are available. The aim of this study was to assess the cardiac neuronal function using 123I-metaiodobenzylguanidine (MIBG)(More)
We extracted L., the newborn of a diabetic mother, for antenatal diagnostic of myocardial hypertrophy and anomaly of foetal heart rate. Post-natal echocardiography showed severe septal myocardial hypertrophy with latero-basal myocardial akinesia. We did not observe a Doppler gradient through the left ventricular outflow. Selective coronary angiography(More)
This article reports on the transhepatic closure of post-Fontan hepatic veins to left atrium fenestration in a 13-year-old girl with left atrial isomerism, dextrocardia, azygos continuation to the left superior vena cava, and median liver. The transhepatic route seemed to be the less tortuous access to the fenestration which was previously partially(More)
Clinical blood isolates from three sequential episodes of endocarditis occurring over a 6-month period in a child with a malformative cardiopathy were investigated. All isolates identified as Abiotrophia defectiva were resistant to erythromycin-clindamycin and to tetracycline-minocycline, due to the presence of sequences homologous to the erythromycin(More)
We report the case a 14-year-old male presented with a perimembranous ventricular septal defect. 2D echocardiography showed both left ventricular to right ventricular and atrial shunt. Left and right ventricular 3D "en face" views of the defect were obtained. 3D echocardiography delineated the morphologic nature of the ventricular septal defect, its shape,(More)
Eosinophilia may be responsible for cardiac injuries of widely varying severity, from acute myocarditis to endomyocardial fibrosis. In this review, we present both the molecular mechanisms that are responsible for these lesions and their clinical and paraclinical aspects. Numerous aetiologies can lead to severe eosinophilia, but these are mainly represented(More)
