Summative Diagnosis:
Cardiovascular defects: Heterotaxy with right pulmonary isomerism and congenital heart disease including transposition of the great arteries (TGA), double outlet right ventricle (DORV), and atrio-ventricular septal defects (AVSD)

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/).
