title: [Situs inversus and dextrocardia. Analysis of the associated congenital heart diseases (author's transl)].
abstract: 13 cases of congenital heart diseases in patients having atrial situs inversus and dextrocardia, all studied by means of angiography, are described following an up to date segmental approach. The type of atrioventricular connection was concordant in the 11 biventricular hearts; double inlet in the 2 univentricular hearts. The mode was always via two atrioventricular valves. In two cases the atrioventricular flows realized a criss-cross condition, being horizontal the interventricular septum, superior the morphologically right ventricle and inferior the morphologically left ventricle. In none of the univentricular hearts was an accessory chamber identified; they were both considered to be of indeterminate type. Ventriculo-arterial connections were: concordant in 3 cases (23%), including one case of Tetralogy with pulmonary atresia; discordant in 3 cases (23%); double outlet in 7 cases *54%). The aortic valve was in the assumed position (left and posterior to the pulmonary valve) only in the 3 cases with concordant as a rule. A ventricular septal defect was actually found in all cases; in one it was associated with pulmonary vascular disease. Obstruction to the pulmonary flow (subvalvular, valvular or vascular) was ascertained in 85% of cases, whereas aortic obstruction was never found. Overall, important congenital heart malformations appear to be frequently associated with situs inversus and dextrocardia. The ventriculo-arterial junction is identified as the most affected point.
