• The aortic valve leaflets appear thin with normal excursion
  • Normal tricommissural aortic valve
  • The tricuspid valve leaflets appear thin with normal excursion
  • The pulmonary valve leaflets appear thin with normal excursion
  • Atrial septum appears intact
  • The right ventricular outflow tract appears of good caliber
  • No aortic regurgitation
  • Normal laminar flow across tricuspid valve
  • Trivial tricuspid regurgitation (narrow blue jet at site of tricuspid valve annulus)
  • Normal laminar flow across the right ventricular outflow tract

The parasternal short axis view is a good view to assess the aortic valve arcitecture, tricuspid valve, right ventricular outflow tract and the atrial septum.
