[Neonatal XXXX --a contribution to the differential diagnosis of the cyanotic newborn @entity1 ].

A cyanotic newborn is described to illustrate and discuss the rare transient @entity997 together with functional @entity1146 . Etiologically the manifold causes of perinatal @entity1763 are to be taken into consideration. The clinical appearance corresponds to type A of transient @entity296 according to the classification of Rowe together with @entity649 and @entity712 . Pathogenetically the disease is based on the different histological consequences of @entity296 of the right ventricle in connection with a delayed fall of the pulmonary arterial resistance. Fetal connections lead to a pronounced right-to-left-shunt. The diagnosis is primarily established by the way of clinical and echocardiographic investigation and pulsed doppler examination. The most important differential diagnosis are in @entity4924 , @entity3885 and @entity1146 of the right ventricular outflow tract. Therapy is conservative. Its aim is to improve myocardial performance and to lower right ventricular afterload. Outcome of @entity1 with neonatal @entity997 is uncertain and depends on the severity of @entity296 . In our @entity1 the course has been uneventful after initial difficulties.
