Double outlet ventricle (DOV) is defined as a congenital heart disease with: (1) both great arteries arising completely, or almost completely (≥90%), from a single ventricle (usually, right ventricle); (2) an aortic valve having no fibre connection with mitral valve; and (3) the only outlet of the other ventricle is a ventricular septal defect (VSD). The incidence of DOV accounts for 1% of all congenital heart disease.1 Clinically there are three common types: Fallot type or double outlet right ventricle (DORV) with subaortic VSD with pulmonary stenosis; Eisenmenger type or DORV with subaortic VSD without pulmonary stenosis and Taussig-Bing type or DORV with subpulmonary VSD. Operative techniques are different according to the position of the VSD and great arteries and the presence or absence of ventricular outflow tract obstruction. The operative difficulty increases in the presence of coronary artery malformation. Recently, our research centre has treated 72 cases of patients suffering from double outlet ventricle. This article is the report of the operative methods and the outcomes.
