Summative Diagnosis:
Cardiac phenotype: Hypoplastic right heart syndrome (HRHS) with hypoplastic tricuspid valve, hypoplastic right ventricle, and right ventricular hypertrophy

Phenotypic Similarity to Human Syndrome:Hypoplastic right heart syndrome (HRHS)

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
1720	Hypoplastic tricuspid valve
1821	Hypoplastic right ventricle (subnormal cavity volume)
3609	Right ventricular hypertrophy
