Congenital Cardiac Surgery Outcomes at Connecticut Children’s Connecticut Children’s closely tracks our congenital cardiac surgery outcomes and reports them to the Society of Thoracic Surgeons (STS) National Database, which is the leading patient safety and quality improvement registry among cardiothoracic surgeons. STAT Mortality Categories The STS reports mortality rates of surgical cases using a scale of 1-5, from least complex to most complex. These categories are also called STAT levels. STAT Category 1 Atrial Septal Defect (ASD), Ventricular Septal Defect (VSD) STAT Category 2 Tetralogy of Fallot, Fontan, Ross STAT Category 3 Glenn, Arterial Switch Operation (ASO), CAVC repair STAT Category 4 Aortic arch, ASO with VSD, aorto-pulmonary shunt, TAPVR, Truncus repair STAT Category 5 Norwood procedure, Truncus Arteriosus with Interrupted Aortic Arch Our Surgical Outcomes (2015-2019) Connecticut Children’s ranks below the STS national benchmarks for mortality, risk-adjusted mortality and median length of stay.
