[Levocardia with ventricular inversion and a single atrium in normal position].

A 12-year child had complete heart block, an abdominal situs inversus with laevocardia. Further investigation demonstrated in addition an inferior vena cava ending into an azygos vein, a shunt at the atrial level and a pulmonary valve stenosis. At operation there was a lone atrium in normal position, a ventricular inversion without transposition of the great vessels. In spite of a corrective operation of the Mustard type, the child died the following day through haemorrhage and low output.
