Purpose
The purpose of this study is to use an experimental diagnostic tool(NIRS), combined with a known screening tool (cranial ultrasound), to analyze and evaluate cerebral blood flow and oxygenation, and determine if abnormal neurodevelopmental outcomes can be predicted and potentially improved upon in pediatric patients undergoing repair for congenital heart disease.

Primary Outcome Measures:
- To determine if the use of cranial ultrasound and multi-source-detector near infrared spectroscopy can identify alterations in cerebral perfusion that are associated with long-term neurologic dysfunction. [ Time Frame: 12 months ] [ Designated as safety issue: No ]Using multi-channel NIRS and pre-, intra-, and post-operative ultrasound, we will measure blood oxygenation levels and try to correlate these levels with 12 month neuropsychological evaluation.
Secondary Outcome Measures:
- 2. Evaluate whether changes in resistive indices as determined by cranial ultrasound after cardiopulmonary bypass are associated with major neurologic dysfunction. [ Time Frame: 12 months ] [ Designated as safety issue: No ]
- 3. Describe regional changes in brain tissue oxygenation during selective cerebral perfusion using near-infrared spectroscopy and determine if there are critical thresholds that correlate with poor neurologic outcomes. [ Time Frame: 12 months ] [ Designated as safety issue: No ]To accomplish this, we will describe differences in cerebral blood flow and oxygenation as related to structural anatomy of the heart. Specifically, we will compare single ventricle and two ventricle hearts with regards to use of cardiopulmonary bypass with or without selective cerebral perfusion. We will also determine if a prolonged reduction in cerebral oxygenation intraoperatively is associated with ultrasound-diagnosed periventricular leukomalacia at discharge.
