[Cerebral AV fistula with cardiac insufficiency in newborns (author's transl)].

A case of arteriovenous aneurysm of the great vein of Galen with congestive heart failure in a newborn infant is presented. Efficiancy of medical management and stop of growth of the head circumference point towards a good prognosis. Patients with this malformation have been divided into four clinical groups presenting with different symptoms in different ages. Anatomy, hemodynamics, clinical picture and diagnosis are considered.

[Transposition of the great arteries: natural history and indications for surgery after balloon-atrioseptostomy (author's transl)].

The natural history of 162 children with transposition of the great arteries is referred, whose first heart catheterization fell between 1967 and June 1975. In 149 of them balloon atrial septostomy (BAS) was performed, with a mean increase in arterial oxygen saturation of 21 %. In 11 cases BAS was repeated after inadequate first BAS, but again without success. In 19 patients an atrial septectomy (Blalock-Hanlon) was performed later on, with 20% mortality. 3 children died during or immediately after BAS. The early mortality after BAS was 13% and the late mortality 17%. These values include the mortality of palliative operations which were necessary to bridge over the time until "corrective" operations could be performed. The operative mortality of Mustard operations was 10% for the simple TGA and 16% for all TGA cases operated on. On the basis of the mortality values of the BAS, of atrioseptectomy (Blalock-Hanlon) and of the Mustard procedure the proceeding after BAS and the indication for operations is thoroughly discussed.

[Right atrial fibroma simulating cyanotic cardiac vitium in a newborn (author's transl)].

The clinical picture in a cyanotic newborn suggests pulmonary atresia or tricuspid atresia. Angiocardiography shows a right atrial tumor, at necropsy a ping-pong-ball sized fibroma is found. Hypoxia and congestive heart failure occurred and the baby died on his eleventh day of life. Uncertain cardiac symptomatology should always raise the suspicion of a cardiac tumor. Cardiac tumors with predominant intramural growth can show pure cardiomegaly- and/or cardiac arrhythmias, congestive failure, while intracavitary growth may lead to various kinds of in- and outflow obstruction and/or embolisations.

[Accidental digitalis intoxication in small children (author's transl)].

Life-threatening, glycoside-induced cardiac rhythm disturbances are often seen following accidental digitalis intoxication in small children. Modern therapeutic management should take into consideration the pharmacokinetics as well as the mechanisms responsible for cardiac and extracardiac symptoms. Discussed are the possibilities of eliminating and inactivating the ingested glycosides, the indications and contraindications for administration of electrolytes, as well as the use of anti-arrhythmic drugs and pacing for cardiac arrhythmias. Special consideration should be given to close observation and instrumental monitoring; ideally these should be carried out in an intensive care unit. Unnecessary loss of time in the management of such cases should be avoided through proper organization of diagnostic and therapeutic activities.

[Deformities of the spine and ribs in embryologically related malformations of the heart with cyanosis].

Three cases of severe costovertebral deformities together with embryologically related cardiac malformations (Fallots Tetralogy and Truncus arteriosus communis) are presented. Two patients died because of their thoracic deformities and limited respiratory function. Relationships to similar bizarre veretebral anomalies are discussed. The cause is probably a teratogenic agent, acting between the fifth to eight embryologic week.

The syndrome of absent pulmonary valve and ventricular septal defect--anatomical features and embryological implications.

Four cases of absent pulmonary valve in combination with ventricular septal defect are reported. In this syndrome hypo- and dysplasia of the pulmonary valve is constantly associated with a big ventricular septal defect, formation of a huge pulmonary artery aneurysm and absence of the ductus arteriosus. Presence or absence of a right ventricular outflow tract obstruction is the criteria for classification into two forms. Absence of the pulmonary valve, right ventricular outflow tract obstruction and a malalignment-type ventricular septal defect produced by a conotruncal malseptation process represent the primary complex of malformations. Consecutive intrauterine cardiac failure is most probably prevented by prenatal closure of the ductus arteriosus. Pulmonary artery aneurysm and also dilatation of the right ventricular outflow tract as well as a whole lot of other coexisting deformities can be explained by a cascade of hemodynamical sequelae started by this ductus closure in utero. An embryological scheme explaining the genesis of this syndrome is derived from a morphological analysis of the constituting incoherent-appearing anatomical features.
