BACKGROUND Assessment of systemic right ventricular (RV) function in patients with hypoplastic left heart syndrome is important during long-term follow-up after Fontan repair. Traditional echocardiographic parameters to evaluate systolic ventricular function are affected by loading conditions. The only generally accepted load-independent parameter of(More)
BACKGROUND Postoperative junctional ectopic tachycardia (JET) occurs frequently after pediatric cardiac surgery. R-wave synchronized atrial (AVT) pacing is used to re-establish atrioventricular synchrony. AVT pacing is complex, with technical pitfalls. We sought to establish and to test a low-cost simulation model suitable for training and analysis in AVT(More)
OBJECTIVES Junctional ectopic tachycardia is a frequent complication after pediatric cardiac surgery. A uniform definition of postoperative junctional ectopic tachycardia has yet to be established in the literature. The objective of this study is to analyze differences in the general and age-related prevalence of postoperative junctional ectopic tachycardia(More)
Background. The causes of cerebral venous thrombosis (CVT) are manifold as is its clinical presentation. Case. We report the case of a CVT following lumbar puncture and intravenous glucocorticosteroid therapy in a female adolescent with a clinically isolated syndrome and risk factors for thrombosis. Conclusion. In adolescent patients with acute inflammatory(More)
OBJECTIVES The purpose of this study is to evaluate the cardiac function in anemic fetuses by tissue Doppler imaging (TDI) measuring the myocardial peak systolic strain (PS) in fetuses before and after intrauterine transfusion (IUT) of red blood cells. METHODS In our prospective clinical study in anemic fetuses, high-frame-rate TDI data files from a(More)
Postoperative junctional ectopic tachycardia (JET) is a frequent complication after pediatric cardiac surgery. Current recommendations on how and when to treat JET are inconsistent. We evaluated the management strategies of postoperative JET in German-speaking countries. We sent an online survey to 30 centers of pediatric cardiology that perform surgery for(More)
BACKGROUND Published data on breast milk feeding in infants suffering from inherited metabolic disorders (IMDs) other than phenylketonuria (PKU) are limited and described outcome is variable. OBJECTIVE We aimed to evaluate retrospectively whether breastfeeding and/or breast milk feeding are feasible in infants with IMDs including organic acidemias, fatty(More)
Accurate assessment of ventricular function is particularly important in children with hypoplastic left heart syndrome (HLHS) after completion of the total cavopulmonary connection (TCPC). For this purpose, two-dimensional speckle tracking (2DST) is a promising technique as it does not depend on the angle of insonation or the geometry of the ventricle. The(More)
