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]
  • Aortic stenosis was probably first described by Lazare Riviere (1589-1655), a French physician in 1663. [1].
