Summative Diagnosis:
Cardiac phenotype: Laterality defect including situs inversus totalis, double outlet right ventricle (DORV), atrioventricular septal defect (AVSD), pulmonary atresia, dual inferior vena cava (IVC)
Non-cardiac defects: pulmonary agenesis, immotile/dyskinetic airway cilia motility

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
0100	Situs inversus totalis
0600	Double outlet right ventricle
1000	Pulmonary atresia congenital
1100	Atrioventricular canal (endocardial cushion defect)
2810	Inferior vena cava anomaly
