title: Hypoxemia explained 36 years later.
abstract: A 37-year-old man who had an atrial septal defect (ASD) corrected as an infant was found to be hypoxemic with a 22% shunt. An MRI scan revealed that the patient's inferior vena cava drained into his left rather than his right atrium, a previously undetected complication of his ASD repair 36 years before.
