[Surgical treatment of congenital heart defects with pulmonary hypertension in children during their 1st year of life under the conditions of extracorporeal circulation].

In the period between 1983 and 1987 operations were carried out on 204 children aged from 25 days to 12 months (body weight of 3 to 10 kg) for congenital heart diseases and pulmonary hypertension. Surgery for ventricular septal defect was undertaken on 173 patients (total mortality 6.9%), transposition of the major vessels with concurrent ventricular septal defect was corrected by Senning's method in 9 patients (mortality 11%), total anomalous pulmonary vein drainage was relieved in 14 patients (mortality 28.6%). No fatal outcomes occurred in correction of an aorto-pulmonary fistula, origin of the aorta and pulmonary artery from the right ventricle, and a common ventricle. In all patients, with the exception of 4 (2 with secondary and another 2 with primary pulmonary hypertension), pressure in the pulmonary artery reduced significantly.
