Summative Diagnosis:
Cardiovascular phenotype: Hypoplastic left ventricle, hypoplastic mitral valve, and dysplastic aortic valve with critical aortic stenosis
Noncardiovascular phenotype: Short snout

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
0300	Hypoplastic left heart syndrome
1400	Aortic valve abnormality
1410	Aortic stenosis
1515	Hypoplastic mitral valve
1811	Hypoplastic left ventricle (subnormal cavity volume)
4906	Non-cardiac abnormality
