3. Inpatient admission: The patient, a six-week-old infant, was admitted for evaluation of a fever. She was placed on IV antibiotics, and blood cultures grew coagulase-negative Staphylococcus. The provider documented "Staph sepsis." Because a murmur was noticed on physical examination, an echocardiogram was done. This revealed physiological peripheral branch pulmonary artery stenosis and a small left-to-right atrial shunt, most likely a patent foramen ovale. Based on these findings, the provider diagnosed patent foramen ovale and pulmonary artery stenosis. Discharge diagnoses: (1) Coagulase-negative, community-acquired staphylococcusepsis; (2) peripheral pulmonary artery stenosis; (3) patent foramen ovale.
