Summative Diagnosis:
Phenotype 1: Cardiovascular defects: Double outlet right ventricle (DORV)/overriding aorta, perimembranous (pmVSD), muscular ventricular septal defect (mVSD)
Phenotype 2: Cardiovascular defects: Coronary artery fistula to right ventricle (RV)

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
0600	Double outlet right ventricle
1310	Ventricular septal defect, membranous
1320	Ventricular septal defect, muscular
1432	Overriding aortic valve
2233	Coronary-cameral fistula to right ventricle
