[Diagnosis and differential diagnosis of heart tumors in infancy and childhood].

The clinical features of 10 children, in whom the diagnosis of a cardiac tumor has been made, are reviewed. There were nonspecific systolic murmurs in 9 patients, depression of the S-T segment in the ECG of 7 children, and premature extrasystoles or supraventricular tachycardia in 4 children. X-ray always showed mild to moderate enlargement of the heart, but an abnormal contour could be detected only in 2 of the patients. While findings of cardiac catheterization were unspecific, the diagnosis could be made angiographically in 8 cases. Invasive studies, however, are now only indicated, if a proper diagnosis cannot be made by means of echocardiography. The diagnosis should be suspected in children with a nonspecific murmur, cardiomegaly and ECG-changes. Usually the diagnosis of a cardiac tumor is an indication for operation.

[A rare combination: persistent ductus arteriosus and pulmonary stenoses. Is there a correlation with rubella embryopathy?].

The combination of patent ductus arteriosus, valvular pulmonary stenosis and/or peripheral pulmonary stenosis is very rare. We examined 23 children with this entity. In 9 children there were findings suggestive of rubella syndrome. 17 of the 23 children were born predominantly between October and March. Most of them showed low birth weights. Regarding the cardiac involvement there was no difference between the children with signs of rubella syndrome and those without noncardiac manifestations. In many children the symptoms of the patent ductus are leading. On evaluation of the noninvasive diagnostic procedures the ECG showed often a right ventricular hypertrophy and the x-ray of the chest showed in most cases a cardiac enlargement. In all patients a heart catheterization was necessary to establish the diagnosis. The review of the literature and the interpretation of our findings seems to suggest that the combination of a patent ductus arteriosus with pulmonary stenosis is a typical manifestation of rubella infection in the heart.

[Risks in heart catheterization and angiocardiography in infancy and childhood].

The results of cardiac catheterization with or without angiocardiography in 689 infants and 1311 children and adolescents were reviewed. In the first week of life 14,81% of the patients died within or after 24 hours of the procedure, 7,41% in the first month of life, 2,78% in the first year. And on the whole the mortality was 0,95%. Four expired after the first month of life and none after the fourth. All those infants who expired were in poor general condition with severe cyanosis and congestive heart failure.

[Unilateral proximal aplasia of the pulmonary artery--studies on the clinical significance and embryologic interpretation].

Description and discussion of the findings in a five month old infant and a six year old boy, in whom unilateral absence of the pulmonary artery contralateral to the aortic arch could be demonstrated by means of angiocardiography. The infant, having absence of the right pulmonary artery associated with patent ductus arteriosus and obstructive pulmonary vascular disease of the left lung died after recurrent pulmonary infections in acute heart failure. The boy with absence of the left pulmonary artery could be shown to have moderate-severe peripheral stenosis at the origin of the right pulmonary artery from the main pulmonary artery. Pulmonary function studies showed normal values. During a follow-up of 5 years the boy doesn't show any symptoms. In both cases an accessory vessel could be demonstrated on the side of the absent pulmonary artery originating from the innominate artery and leading to the hilum of the corresponding lung. Embryologically these vessels probably represent persistence of the second primitive ductus arteriosus. According to its development the disease more precisely should be designated as unilateral proximal aplasia of the 6th ventral aortic arch, i.e. of the definitive pulmonary artery.
