Pulmonary vascular obstructive disease and hemoptysis in a child with tetralogy of Fallot and patent ductus arteriosus.

: Tetralogy of Fallot (TOF) and patent ductus arteriosus complicated by pulmonary vascular obstructive disease (PVOD) and hemoptysis in a 5-year-old girl are described. The echocardiogram was typical of TOF, as well as ductus arteriosus and right aortic arch. Cardiac catheterization revealed a pulmonary vascular resistance of 44 hybrid resistance units, and the pulmonary-to-systemic resistance ratio was 1.4. Diagnosis of PVOD was made by cardiac catheterization. Angiography revealed a bronchial artery arising from the left subclavian artery. PVOD itself, rupture of a bronchial artery or both, were considered the contributory causes of hemoptysis in this patient.
