OVERVIEW
Understanding the essential imaging and Doppler modalities

The behaviour of the ultrasound within the body is described by the formula:

Propagation velocity = wavelength × frequency

Wavelength and frequency are inversely related.


Amplitude
Increasing the frequency will decrease the
wavelength, which is good for resolution. But there is
a trade off: with increased frequency, penetration will
also decrease.
Wavelength

Pulsed wave and color Doppler are similar: they but cannot localize within the ultrasound beam. So

Preparing to scan

Before you begin your scan, remember to ask yourself the following questions:

• Have you got the right equipment? • Have you explained what you are going to
do in a way your patient understands and
• Have you got the right patient? gained verbal consent?

• Have you entered the patient’s details • Have you made allowances for any

individual patient preferences?
• Have you attached the ECG?

Recognizing artifacts

An artifact can make it look like there is something present that isn’t there, or it may hide structures from
being seen. If you suspect an artifact, try one of the following:

• Image from other views.


• Alter the machine settings.
• Observe whether it looks and moves physiologically.

Controlling infection

This is an important component of performing an echo and will be informed by your institution’s policies
and practice guidelines. As a general rule, anything that touches the patient should be cleaned carefully
after every scan. Some cleaning agents can damage ultrasound probes, so make sure you use a method the
manufacturer supports and it’s good practice to routinely check the probe for damage before you use it.

THE VENTRICLES AND


PULMONARY PRESSURES
Evaluating left ventricular size and hypertrophy

National echo societies and echo guideline documents recommend slightly different normal ranges
and severity criteria for left ventricular (LV) size. Ideally you should use the same values as the other
echocardiographers in your institution to ensure uniformity of practice. If you do not have this guidance
available, these tables may help:

Left ventricular diastolic cavity diameter

Mildly Moderately Severely


Normal dilated dilated dilated

Women
LV diastolic diameter (cm) 3.9–5.3 5.4–5.7 5.8–6.1 ≥6.2

Men
LV diastolic diameter (cm) 4.2–5.9 w6.0–6.3 6.4–6.8 ≥6.9

Measure using a leading edge convention at the tip of the mitral valve leaflets in the parasternal long-axis view.

If you have a very small or large patient, you


may need to correct for body size using body
surface area.

Identifying left ventricular regional wall abnormalities

Use these diagrams to guide you when you assess regional wall abnormalities. The walls can be described
as ‘normal’, ‘hypokinetic’, ‘akinetic’, ‘dyskinetic’, ‘aneurysmal’, or ‘hyperkinetic’. The 16- and 17-segment
models have different terms for some of the walls so make sure you use the same model as your colleagues.

Assessing intracardiac masses

Check:
• Site, attachment, size, shape, echo density, mobility, and any invasion of the myocardium.
• Then integrate the echo findings with the patient’s clinical status.

Think of thrombus if there is slow moving blood (e.g., poor left


ventricular function or a dilated left atrium).

A vegetation resulting from infective endocarditis is likely to be


situated on a valve and cause destruction. This may be seen
echocardiographically as increasing regurgitation.

The most common benign intracardiac tumor is a myxoma,


which is usually in one of the atria (left more commonly) and
attached to the atrial septum. It may, or may not, have a stalk.

Primary malignant cardiac tumors are very rare.
