Comparative Study
[Evaluation of surgical treatment results of coarctation of the aorta in neonates and young infants].
The authors present the analysis of surgical results obtained for coarctation of the aorta (CoA) in children less than 1 year of age. The material consisted of 103 infants (62 Males and 41 Females) aged 0.33-10.5 months (x = 3.3 +/- 2.6 months) treated between January 1, 1985 and December 31, 1999. All the patients were subjected to a detailed physical examination, ECG, chest X-ray and comprehensive echocardiography, while 12 children had additional hemodynamic studies and angiocardiography. Two groups were distinguished among the investigated children: Below 3 months of life (Group 1, N = 65) and above 3 months of life (Group 2, N = 38). In 69 infants, (including 55 from Group 1 and 14 from Group 2), the recommendation for surgery was circulatory failure, while in 34 infants (10 from Group 1 and 24 from Group 2), the recommendation for surgery considerable systemic hypertension with absent femoral pulses. In 76 patients, the Waldhausen procedure was performed, while 24 were subjected to aortic isthmus angioplasty using a Gore-Tex patch and 3 were subjected to end-to-end anastomosis. Six patients died, including 5 from Group 1 and 1 from Group 2. The remaining 97 infants (60 from Group 1 and 37 from Group 2) were followed-up for a mean period of 96.2 +/- 48.2 months. Postoperative recoarctation was encountered in 12 patients (12.4%); the condition was more predominant in Group 1 (16.6%) than in Group 2 (5.4%), but, no statistical significance was noted (Chi 2 = 2.677, p = 0.102). Despite the repair of aortic coarctation, systemic hypertension was noted in 17 children (17.5%) and it was equally common in both groups, but, twice as frequent in children with recoarctation. ⋯ 1. CoAo correction in children below 3 months of age is associated with an increased risk of recoarctation. 2. Even when surgical treatment of CoAo is attempted very early in life, the risk of elevated systemic blood pressure is not completely eliminated.

Comparative Study
[The role of transesophageal echocardiography (TEE) in assessment of left ventricular tract obstruction].
Twelve children with subaortic stenosis were analysed. Nine of them developed left ventricular outflow obstruction after surgery for congenital heart disease (VSD + IAA, VSD + DORV, VSD + TGA, VSD + CoA) and then developed an isolated form of primary stenosis. ⋯ TTE was sufficient to assess isolated subaortic stenosis. In children after cardiosurgery, TEE was more reliable and provided more detailed visualisation of the stenosis and its relationship to surrounding structures.

The article presents most important changes in international guidelines for adult cardiopulmonary resuscitation. In this article guideline changes in basic and advanced life support published in Guidelines 2000 for Cardiopulmonary Resuscitation and Emergency Cardiovascular Care--a Consensus on Science are discussed. Major changes in guidelines presented in this article include: pulse check, ventilation technique for rescue breathing, compression technique, abdominal thrust recommendations, precordial thump, universal algorithm changes.

The authors examined intellectual and socio-emotional functioning of 39 subjects suffering from Duchenne muscular dystrophy. Their school situation, access to rehabilitation and a quality of familial upbringing attitude were characterized, as well. No significant differences concerning I. Q. between sick children and healthy population were found.

Repolarization disorders leading to ventricular tachyarrhythmias are common causes of sudden cardiac death. Two of the disorders have been recently described at the molecular level revealing gene mutations: long QT syndrome, characterized by a prolonged QT interval corrected for heart rate and high incidence of malignant ventricular tachycardia, mainly torsade de pointes, and Brugada syndrome characterized by a ST segment elevation in the right precordial leads (V1-V3), right bundle branch block and idiopathic ventricular fibrillation. ⋯ On the basis of these repolarization disorders lay ion channel dysfunctions. The new discoveries may in the future allow a better diagnosis by genetic testing and raise the possibility of effective treatment by means of the gene-specific therapy.
