title: [Severe hypoxia due to persistent left supra vena cava draining to the left atrium after weaning from cardiopulmonary bypass in a patient with endocardial cushion defect].
abstract: We report a case of severe hypoxia after weaning from cardiopulmonary bypass in a ten-month-old patient with endocardial cushion defect. The severe hypoxia was improved abruptly when the persistent left supra vena cava (PLSVC) was ligated. The hypoxia, therefore, was considered to be caused by venous blood which was directly drained into the left atrium through the PLSVC. In cases with large right-to-left shunt which is difficult to explain only by intracardiac shunt, attention must be paid to existence of PLSVC directly draining into the left atrium.
