Overview
Echocardiography is commonly used to diagnose and monitor the progress of heart failure. This modality uses ultrasound to determine the stroke volume (SV, the amount of blood in the heart that exits the ventricles with each beat), the end-diastolic volume (EDV, the total amount of blood at the end of diastole), and the SV divided by the EDV, a value known as the ejection fraction (EF). In pediatrics, the shortening fraction is the preferred measure of systolic function.
Abnormalities Detected / Evaluated on Echocardiography in Congestive Heart Failure
The most useful diagnostic test in the evaluation of patients with or at risk for HF (eg, postacute MI) is a comprehensive 2-dimensional echocardiogram; coupled with Doppler flow studies, the transthoracic echocardiogram can identify abnormalities of myocardium, heart valves, and pericardium. Echocardiography can reveal subclinical HF and predict risk of subsequent events.[1]
LVEF is reduced, LV structure is abnormal, and other structural abnormalities are present that could account for the clinical presentation. This information should be
Echocardiography can be used in the following ways:
- To evaluate left ventricular function and ejection fraction to distinguish systolic dysfunction with a low ejection fraction (<40%) from diastolic dysfunction with a preserved ejection fraction.
- LV structural abnormalities
- To assess for the presence of regional wall motion abnormalities that would suggest an ischemic basis for the heart failure
- Detection and quantification of mitral regurgitation
- Detection and quantification oof aortic stenosis
- Measurement of pulmonary artery pressure
- Pericardial diseases such as cardiac tamponade can be rapidly diagnosed by echocardiography.
- Echocardiography may also aid in deciding what treatments will help the patient, such as medication, insertion of an implantable cardioverter-defibrillator or cardiac resynchronization therapy.
Echocardiographic findings must be quantified, including numerical estimates of EF measurement, ventricular dimensions, wall thickness, calculations of ventricular volumes, and evaluation of chamber geometry and regional wall motion.
Documentation of LVEF is an HF quality-of-care performance measure.[2]
Right ventricular size and function as well as atrial size and dimensions should also be measured.
All valves should be evaluated for anatomic and flow abnormalities.
Many of these abnormalities are prognostically important and can be present without manifest HF.[3]
Serial echocardiographic evaluations are useful because evidence of cardiac reverse remodeling can provide important information in patients who have had a change in clinical status.

Echocardiography in Patients Presenting With Heart Failure (DO NOT EDIT) [4][5]
| Class I |
| "1. Two-dimensional echocardiography with Doppler should be performed during initial evaluation of patients presenting with heart failure to assess left ventricular ejection fraction, left ventricular size, wall thickness, and valve function. Radionuclide ventriculography can be performed to assess left ventricular ejection fraction and volumes. (Level of Evidence: C) " |
| "2. Repeat measurement of EF and measurement of the severity of structural remodeling are useful to provide information in patients with HF who have had a significant change in clinical status; who have experienced or recovered from a clinical event; or who have received treatment, including GDMT, that might have had a significant effect on cardiac function; or who may be candidates for device therapy.(Level of Evidence: C) " |
| Class III (No Benefit) |
| "Routine repeat measurement of LV function assessment in the absence of clinical status change or treatment interventions should not be performed.[6] (Level of Evidence: B)" |
