Twenty-five cases of double-inlet left ventricle, 23 in atrial situs solitus and 2 with dextroisomerism are described. Twenty had both atrioventricular valves and in 3 a common atrioventricular valve connected to the left ventricle. In rest, the left atrioventricular valve was straddling over the left-sided right ventricle in about 15%. ⋯ In 22 cases angiography determined the type of atrioventricular connection. Double inlet left ventricle is one of the most challenging diagnosis in congenital heart disease. Considering its lack of clinical specificity and according to our results, the electrocardiogram, echocardiogram and angiographic findings are of great help for its identification.
