title: Echocardiographic identification of thymic hypoplasia in tetralogy of fallot/tetralogy pulmonary atresia.
abstract: The use of transthoracic echocardiography to detect the presence of thymic tissue has been reported in patients at risk for graft versus host disease. We confirmed the accuracy of this method in patients with tetralogy of Fallot and tetralogy of Fallot/pulmonary atresia, and suggest using a threshold distance of 6.1 cm/m2 (5.5 to 6.3 cm/m2).
