Atypical electrocardiogram and echocardiogram in a patient with Bland-White-Garland syndrome in association with atrial septal defect.

We describe an uncommon association: atrial septal defect with an anomalous left coronary artery originating from the pulmonary trunk (Bland-White-Garland syndrome) in a 2-month-old patient with Klinefelter syndrome. Electrocardiogram and two-dimensional echocardiogram were not typical of Bland-White-Garland syndrome in this patient which delayed the diagnosis.
