A 12-year-old girl complained of tachycardia and dyspnea after exertion but without
cyanosis. Her echocardiogram showed an ASD and a widened inferior vena cava. A difference
in PO2 between inferior and superior vena cava was evident. An anastomosis between left
atrium and pulmonary vein, and a long oval pericardium to cover the opening of the
descending vein and ASD into left atrium were performed during cardiopulmonary bypass.
The patient recovered without complications.
