Summative Diagnosis:
Cardiovascular defects: Heterotaxy with congenital heart disease (CHD) such as double outlet right ventricle (DORV), atrio-ventricular septal defect (AVSD), common atrium, and pulmonary artery (PA) stenosis

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
1622	Pulmonary artery stenosis
3804	Congenital heart disease
3817	Abdominal situs ambiguous (abdominal heterotaxy)
