  2. Library: Normal Module
  3. Lesion: Normal Echocardiogram
  4. View: Subcostal short axis RVOT
  • Normal caliber right ventricular outflow tract
  • The pulmonary valve leaflets appear thin with good valvar excursion
  • Normal right and left ventricular size and systolic function
  • The left ventricle demonstrates two normal sized well spaced papillary muscles
  • The ventricular septum appears intact without evidence of ventricular septal defects from this imaging plane
  • Normal laminar flow across the right ventricular outflow tract and pulmonary valve
  • The ventricular septum appears intact without evidence of ventricular septal defects from this imaging plane
  • Normal laminar flow across the right ventricular outflow tract and pulmonary valve
  • No pulmonary regurgitation
  • The ventricular septum appears intact without evidence of ventricular septal defects from this imaging plane

This view obtained from subcostal imaging plane is optimal to assess caliber and flow across the RVOT and pulmonary valve.

  • Transducer on abdomen just below xyphoid process
  • Notch at 6 o'clock
  • Tilt the ultrasound probe leftward
  • RVOT obstruction
    • Double chambered right ventricle
    • Subvalvar infundibular pulmonary stenosis (TOF)
  • Pulmonary stenosis
    • Dysplastic pulmonary valve
    • Hypoplastic pulmonary valve
  • Supravalvar pulmonary stenosis
  • Ventricular septal defect
