Fetal View | Anatomy Seen: | Measurements Taken: |
Fetal Apical four Chamber | • 2 atria
• 2 ventricles
• MV & TV
• IVS & IAS
• Pulmonic veins | PW Doppler of MV and TV |
Fetal Subcostal 4 Chamber | • 2 atria
• 2 ventricles
• MV & TV
• IVS & IAS
• Pulmonic veins | M-mode:
• LV size and function
• IVS & posterior wall thickness
• RV internal dimension
• Sizes of both atria
Doppler & color flow of foramen ovale |
Long Axis View of Aorta | • Proximal aorta
• Ant. aortic wall continuous with IVS
• Posterior aortic wall continuous with AMVL
(Same as PLAX view) | PW Doppler & color flow can interrogate AoV for AI and AS |
Long Axis View of Pulmonary Artery | • Shortened RV
• PV & PA | PW Doppler & color flow used to evaluate for PI & PS |
Short Axis of Ventricles | • RV & LV
• IVS | M-mode:
• Ventricular free wall
• IVS
• Chamber sizes
Color flow Doppler used to evaluate for abnormal VSD’s
• If found, use PW Doppler to interrogate |
Short Axis of Great Vessels | • RA, RV, LA
• TV, PV
• PA and DA
(Same as adult PSAX aortic level) | M-mode: Measure size of PA
• PW and color flow of TV and PV
• Also evaluate ductus arteriosus |
View of Aortic Arch | • Ascending aorta
• Arch & branches (innominate, LCC & LSA)
• Descending aorta
• Right pulmonary artery
• Foreshortened LA | • Color flow and PW to view velocity of aorta
• Used to rule out narrowing of aorta |
View of Ductal Arch | • Ductus arteriosus
• PA, aorta
• PV, RVOT
• AV, TV, LA | Doppler to assess ductus arteriosus |
View of IVC & SVC | • RV, RA, TV
• IVC, SVC | PW Doppler and color flow to assess venous flow |
