Study Notes
Apical Views in Echocardiography
-
Apical 4 View:
- Alignment requires the plane marker to point to the patient's left posterior axilla, directed towards the right shoulder.
- Visualization of the apical myocardium can be challenging due to the proximity of the true apex.
- The intratrial septum (IVS) and interatrial septum (IAS) appear vertical in the image.
- Fossa ovalis and high IVS are poor reflectors because of their membranous structure.
-
Apical 3 View:
- Essential for identifying the right and left sides of the heart.
- Demonstrates the presence of the moderator band and the septal and mitral valve leaflets.
- The transducer should be inserted more apically than the anterior leaflet to provide clearer images.
- Pulmonary veins can be observed entering the left atrium (ZA).
-
Apical 5 View:
- The transducer is angled anteriorly to visualize the outflow tract, aortic valve, and ascending aorta.
- Atrioventricular (AV) valves are less clearly defined in this plane.
-
Apical 2 View:
- Achieved by rotating the scan plane counterclockwise from the standard apical 4 chamber view, focusing solely on the left side of the heart.
- Allows visualization of the anterior and inferior walls.
-
Apical Long Axis View:
- Results from further counterclockwise rotation from the apical 2 position, capturing the aorta and the apical long axis.
- Ideal for assessing flow with color Doppler as the flows are parallel to the ultrasound beam.
- Simultaneously visualizes both inflow and outflow tracts within this plane.
- 2D imaging is more effective at perpendicular angles, while Doppler is better when aligned parallel to the flow.
