Summative Diagnosis:
Cardiovascular defects: Hypoplastic aorta, aortic atresia, dysplastic semilunar valves, overriding aorta, perimembranous (pmVSD) and muscular (mVSD) ventricular septal defects,and coronary fistula.

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
0320	Aortic atresia
1310	Ventricular septal defect, membranous
1602	Dysplastic pulmonary valve
2230	Coronary fistula (arterio-venous or arterio-cameral)
2703	Hypoplasia ascending aorta
3804	Congenital heart disease
