She was diagnosed prenatally with Tetralogy of Fallot. Tetany due to hypocalcemia is noted in the first 48 hours of life and requires treatment. A chest x-ray obtained is notable for absence of a thymic shadow (Figure 216-2). Immunologic laboratory data reveal CD3+ T cells are <500/mm3. Chromosomal analysis is sent and reveals a deletion of chromosome 22q11.2. She undergoes surgical repair of her heart lesion at one week of age, and requires close follow-up of her cardiac, immunological, and metabolic problems.
