Views to study right ventricle
From Echocardiography in ICU
Right ventricle anatomy
The right ventricle is the most anterior cardiac chamber. It has 3 main components:
- Inlet: tricuspid valve, chordae tendineae, and papillary muscles
- Trabeculated apical myocardium
- Infundibulum, or conus, which corresponds to the smooth myocardial outflow region
Its shape is triangular when viewed from the side and crescent shaped when viewed in cross section.
A video example of normal right ventricle size and function is displayed in the images library.
The right ventricle is the chamber at the top of the image, the closest to your probe. In this view you will visualize the right ventricle outflow tract. This view will give you an idea of the RV size and function.
- At the level of the basis of the heart (aortic valve at the center of the image), you will visualize the RA on the left of the screen, RV outflow tract at the top of the screen. You will see the tricuspid valve between the RA and the RV. This can be a good view to look for tricuspid regurgitation and estimate the right ventricle systolic pressure.
The right ventricle is on the left of the screen. In this view you can look at the size and function of the RV. If the probe is too medial or too high, you may overestimate the size of the RV compared to the size of the LV. Apical 4 chamber view is also a good view to look for a tricuspid regurgitation and estimate right ventricle systolic pressure.
The right ventricle is the chamber closest to you, next to the liver. This is a good view to look for RV size, wall thickness and function.
