Summative Diagnosis:
Cardiac phenotype: Dextrocardia and atrioventricular septal defect associated with heterotaxy.
Noncardiac phenotype: Left pulmonary isomerism, situs inversus

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
0110	Dextrocardia
0190	Heterotaxy syndrome
1100	Atrioventricular canal (endocardial cushion defect)
4239	Left bronchial isomerism
