Summative Diagnosis:

Fyler Codes
The Fyler code developed by The Boston Children's Heart Foundation in Boston Children's Hospital provides a hierarchical clinical diagnosis of congenital cardiovascular defects and other disorders. These codes are used to delineate pathology in the mutant mouse models that parallel human disease and can be cross referenced to the International Pediatric and Congenital Cardiac Code (IPCCC) (http://www.ipccc.net/).

Fyler Code ID	Code Description
0520	Truncus arteriosus type ii
1241	Transverse arch obstruction
1252	Interrupted aortic arch type b
1300	Ventricular septal defect
1432	Overriding aortic valve
