ABSTRACT

ABSTRACT | REFERENCES

A 3-week-old male infant was seen for routine evaluation. His parents reported no problems other than decreased feeding for 4 to 5 days. The infant was mildly pale and tachypneic. His weight was 3700 g (60 g above birth weight). Respirations were 70/min. There was a grade 2/4 systolic ejection murmur at the upper left sternal border. Pulses were normal. He was referred for further diagnostic studies, including a chest roentgenogram (Fig 1), an echocardiogram (Fig 2), magnetic resonance imaging (Fig 3), and angiography (Fig 4).

Denouement and Discussion

Anomalous Origin of the Right Pulmonary Artery From the Aorta: 'Hemitruncus' Hemitruncus is an unusual cardiovascular malformation in which one pulmonary artery, usually the right,¹ arises from the ascending aorta, while the opposite pulmonary artery connects normally to the main pulmonary trunk. An associated patent ductus arteriosus is common,² and intracardiac defects are occasionally present.^1,2 The diagnosis must be applied cautiously to avoid confusion with
