[Intraventricular conduit for complex forms of transposition of great vessels (author's transl)].

Complex forms of transposition of great vessels necessitate different approaches to correction. In a case of double outlet right ventricle with d-transposition and atrioventricular concordance and a subvalvular pulmonary stenosis an intraventricular conduit with a 16 mm Dacron vascular prosthesis was used. This was anastomosed in an acute angular manner with the muscular margins of the VSD and routed to the base of the aorta. Surgical and anatomic implications are discussed.
