1918. Cardiovascular disease in children with marfan syndromeAndrej Robida, 1987, izvirni znanstveni članek Povzetek: To study the cardiovascular changes in children with Marfan syndrome the hospital records of 27 children with this syndrome admitted to our institution between 1975 and 1984 were reviewed. Echocardiographic examinationwas done in all of them. Heart catheterization and angiocardiography were performed in 7 children. 15 children were without cardiovascular involvement (mean age 7.9 years). Twelve children with cardiovascular abnormalities (mean age 12.3 years) were significantly older than children without cardiovascular disease (P<0.02). The most frequrnt cardiovascular abnormality (9 children) was mitral valve diseas (mitral regurgitation, mitral valve prolapse with and without regurgitation). In one patient artificial mitral valve was inserted. Aortic root aneurysm was found in 7 children, in some of them in combination with mitral valve disease. Fusiform aneurysm of thoracic aorta together with aortic root aneurysm was present in one child. In 2 patients tetralogy of Fallot was diagnosed. This review shows that the cardiovascular system is more frequently affected in older children and that about half of the children suffer from cardiovascular disease. Mitral valve involvement predominates. Surgery for the correction of the cardiovascular abnormalities in children with Marfan syndrome is seldom required.

1920. Complications in cardiac catheterization and angiocardiography in infants and childrenAndrej Robida, 1987, izvirni znanstveni članek Povzetek: Complications of cardiac catheterization and angiocardiography were reviewed retrospectively in 1074 neonates, infants, and children studied from 1st January 1981 to 31st December 1985. Overall complication rate was 5.2% (56 complications in 54 children). There were 3 cases of complications was 3.8% and was higher in infants younger than 4 months (P<0.001), and in moderalety and critically ill patients than in asymptomatic and mildly ill patients (P<0.001). The highest proportion of major complications occured in patients with truncus arteriosus communis, double outlet right ventricle, atrioventricular septal defect, univentricular heart, transposition of the great arteries, and tetralogy of fallot. Arrhythmias were encountered in 66.1%of all major and minor complications. In minor complications the differences in frequency were not found beteen various age and clinical groups (P>0.05). The study showed that higher catheterization risk of major complications could be predicted from the age, clinical status, and heart defect of the patient.
