A 24-year-old G4P4031 Caucasian woman presents to the emergency department approx. 10–12 hours after home delivery of a 2.8 kg (6.3 lb) boy. Her last menstrual period is estimated to be around 8 months ago. She had no prenatal care but is well-known to the obstetrics department for multiple miscarriages over the last 6 years. All of her pregnancies were a result of a consanguineous relationship with her 33-year-old first cousin. She states that the delivery was uneventful and she only had a small amount of vaginal bleeding after birth. The infant seemed healthy until an hour ago when he became unresponsive. His body and arms are blue. He is hypotonic in all 4 extremities. On ECG, there is evidence of left axis deviation. Cardiac auscultation reveals the findings in the audio file. Despite resuscitation efforts, the baby passes away soon after the presentation. Which of the following is another pathologic or radiologic finding most likely present in this neonate?
