A 2-year-old girl is brought to the physician because of episodes of turning blue while playing over the past 6 months; the episodes have been increasing in frequency over the past month and occur most often when she is agitated. She was born at term and weighed 3317 g (7 lb 5 oz). She has a normal diet for her age. She is at the 25th percentile for height and weight. Her temperature is 37°C (98.6°F), pulse is 100/mm, respirations are 26/mm, and blood pressure is 80/46 mm Hg. Pulse oximetry on room air shows an oxygen saturation of 87%. The lungs are clear to auscultation. There is a heave at the left sternal border. A grade 3/6, harsh systolic murmur is heard at the left sternal border with radiation to the axilla. An x-ray of the chest shows decreased pulmonary vascularity and a prominent right ventricle.
