Heart Surgery in Infants With Hemophilia

We describe 2 infants with hemophilia A who had heart surgery under cardiopulmonary bypass with factor VIII replacement therapy, and we recommend a guideline for factor VIII support for cardiac surgery. One child had repair of total anomalous pulmonary venous connection. The second had cardiac catheterization followed by repair of ventricular septal defect and total anomalous pulmonary venous connection. Close collaboration between hematologist, laboratory, cardiologist, and cardiac surgeon is crucial in successful management of coagulation abnormalities during and after surgery.
