Summative Diagnosis:
Cardiovascular defects: Persistent truncus arteriosus (PTA) Type I and aortic arch anomalies such as right aortic arch (RAA), vascular ring and ventricular septal defect (VSD)
Noncardiovascular defects: Thymic hypoplasia and nasal hemorrhage.

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
0500	Truncus arteriosus
1300	Ventricular septal defect
2720	Right aortic arch
2760	Vascular ring
3804	Congenital heart disease
