Fifty four operations of one and a half ventricular correction were made for the treatment of congenital heart failure (CHF) in 1999-2006. Age of the patients varied from 1 yr 3 mo to 29 yr. Indications to the use of this method are discussed along with analysis of its role in the surgical treatment of CHF. Two-directional cavopulmonal anastomosis in certain complex forms of CHF reduced volume load on the right ventricle and thereby promoted success of its radical correction. One and a half ventricular correction involved the hypoplastic and functionally compromised right ventricle and pulmonary circulation and therefore created more favourable conditions for circulation.
