Summative Diagnosis:
Cardiovascular phenotype: Heterotaxy syndrome (ambiguous lung lobation) with congenital heart disease: Double outlet right ventricle (DORV), atrial-ventricular septal defect (AVSD) and dual inferior vena cava (IVC)

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
0190	Heterotaxy syndrome
0606	DORV + AVSD (AV canal)
1100	Atrioventricular canal (endocardial cushion defect)
1140	Common atrium
2810	Inferior vena cava anomaly
3804	Congenital heart disease
4235	Pulmonary malformation
