• Aortic valve appears to have thin leaflets with normal systolic excursion
  • Normal appearing aortic root, sinotubular junction and ascending aorta
  • Normal laminar flow across subaortic, aortic valve and supravalvar aortic region
  • No aortic regurgitation

Still frame measurement of aortic dimensions

  1. Aortic valve
  2. Aortic root
  3. Sinotubular junction

This parasternal long axis view focuses on the left ventricular outflow tract, aortic valve, aortic root, sinotubular junction and ascending aorta.

  • Transducer placed at the left sternal border
  • 3rd or 4th intercostal space
  • Notch pointed towards the patient's right shoulder (11 o'clock)
  • Ultrasound beam zoomed or sector width narrowed to focus on aortic valve, root, STJ and ascending aorta
  • Aortic root dilation or aneurysm (Marfan Syndrome)
  • Ascending aortic dilation (bicuspid aortic valve)
  • Aortic regurgitation or stenosis
  • Subaortic membrane
