Our intent is to review hospital medical records, the cardiothoracic surgical database and neurological database at Children’s Healthcare of Atlanta to assess their clinical and functional outcomes. We will review surgery information, clinic visits to Sibley Heart Center Cardiology, and echo, MRI and neurological testing results as well as mortality for these patients. No patient will be contacted. This retrospective study is important as a follow-up to the initial prospective pilot study as it will provide information regarding the clinical outcome of the patients.
