Echo-Doppler (ED) techniques were used to estimate the time of closure of the ductus arteriosus in 30 normal neonates. We found that after birth there was a left-to-right (L-R) shunt through the ductus, which disappeared within 14 hours in 50% of the neonates investigated. Furthermore, patency of the ductus was not associated with a murmur. After closure of(More)
Percutaneous transluminal balloon angioplasty was performed in five children with coarctation restenosis. After angioplasty the pressure gradient had decreased considerably in four patients. In all patients aortography showed an increase in the diameter of the lumen at the site of the restenosis. All patients were normotensive the day after angioplasty.(More)
Dilated cardiomyopathy (DCM) is characterized by dilation of ventricular walls and the reduction of cardiac contractillity, caused by loss of myofibrils and apoptosis of the myocytes. Histochemical assessment of myocardial biopsies is commonly used to monitor these events. Here we report the use of immunohistochemistry for alpha-actin in semithin serial(More)
Perinatal outcome of fetal supraventricular tachycardia. Report of 5 cases and review of the literature. Fetal supraventricular tachycardia (fsVT) is a rare cardiac arrhythmia and is associated with a mortality of 12%. The last decade fsVT has been detected more frequently probably on account of routine fetal monitoring. The outcome of 108 previously(More)

The pulsed Doppler principle enables us to study the bloodflow velocity at specific points in the heart and great vessels. In such aorto-pulmonary connections as patent ductus arteriosus, aorto-pulmonary window and truncus arteriosus the bloodflow velocity patterns are typical of the malformation. Based on knowledge of these abnormal flow patterns the(More)
