The Meaning Behind STAT Scores & Categories
The STAT (The Society of Thoracic Surgeons-European Association for Cardio-Thoracic Surgery) score is a tool designed to analyze the risk for mortality associated with congenital heart surgery procedures.
The categories range from Category 1 to Category 5. Procedures associated with lowest mortality rates are in Category 1, and procedure associated with highest mortality rates are in Category 5.
To help explain our outcomes graphs, some common diagnoses/procedures and the associated STAT Category are listed below. If you wish to know the specific category your child’s diagnosis/procedure belongs to, please ask your cardiologist or cardiac surgeon at your next visit.
