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
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.
- 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.
