Abstract:
The presence of cyanosis following repair of congenital cardiac defects may result from several different mechanisms. We report two patients in whom early postoperative arterial hypoxemia manifested by cyanosis was caused by right-to-left interatrial shunting. Two-dimensional contrast echocardiography correctly identified the site and direction of shunting, leading to surgical correction of the complication.
