Anatomy
- There is hypertrophy of the infundibular muscle causing obstruction.
- The isolated form is rare, more commonly develops in response to an underlying VSD.
Clinical Features
- Similar to valvar pulmonic stenosis.
- Aortic stenosis was probably first described by Lazare Riviere (1589-1655), a French physician in 1663. [1]
