[Treatment of single ventricle by direct atriopulmonary anastomosis without tube or valve. Apropos of a case operated on].
A case of single ventricle with pulmonary stenosis operated at 20 years of age by direct atrio-pulmonary anastamosis is presented. This procedure in contrast to classical techniques does not use an intraventricular patch or a valved ventriculo-pulmonary conduit. It is an adaptation of the Fontan technique initially proposed for tricuspid atresia. The operation consisted of closing the right atrioventricular orifice with a piece of Dacron, suturing the pulmonary valves (which were stenosed) and connecting the right atrium and pulmonary artery by a direct anastamosis using the auricle. The clinical result remains satisfactory one year after surgery: the cyanosis has regressed, the functional tolerance is perfect, there is no hepatomegaly and the patient is in sinus rhythm. The technique is very simple and involves less risk to the His bundle than intraventricular septalisation. It should be reserved to cases of single ventricle with low pulmonary pressures and resistance without cardiac failure. The long-term prognosis depends on the tolerance of the right atrium and is, at present, unknown.
