Summative Diagnosis:
Cardiac phenotype: Double outlet right ventricle (DORV), atrioventricular septal defect (AVSD), aortic arch anomalies including right aortic arch (RAA) and/or aberrant left subclavian artery, vascular ring, and aortic valve atresia

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
1100	Atrioventricular canal (endocardial cushion defect)
1400	Aortic valve abnormality
2720	Right aortic arch
2730	Aberrant left subclavian artery
2760	Vascular ring
