An echocardiogram is an ultrasound examination that shows the heart moving in real time. Also called an echo or cardiac ultrasound, it helps clinicians assess the heart’s chambers, pumping function, valves, and the direction of blood flow. An echocardiogram does not use ionizing radiation and is different from an electrocardiogram (ECG or EKG), which records the heart’s electrical signals.
Patients may be referred for an echo because of shortness of breath, a heart murmur, swelling, or a question raised by another examination. For enquiries about available physician-requested imaging in Kuwait, IMAGES Diagnostic Center has two active branches:
What Does an Echocardiogram Show?
An echocardiogram uses a probe, known as a transducer, to send ultrasound waves toward the heart. Returning echoes are processed into moving images that allow clinicians to assess the heart’s structure and function. A Doppler component can estimate the direction and speed of blood flow through chambers and across valves.
According to the American Heart Association’s echocardiogram overview, an echo can help investigate heart failure, heart murmurs, and problems with the heart’s structure. It is useful because it shows motion, not just a still picture.
Why Might a Doctor Order an Echocardiogram?
To Investigate Shortness of Breath or Unexplained Swelling
Breathlessness may have several causes, including lung disease, anemia, and heart conditions. An echo can assess ventricular pumping and filling patterns, valve function, and other findings that may help the clinician determine whether the heart is contributing to symptoms. Swollen ankles alone do not establish heart failure.
To Assess a Heart Murmur or Suspected Valve Disease
A murmur is a sound heard during a clinical examination that may reflect normal blood flow or a heart valve problem. Echocardiography can help show whether a valve is narrowed, leaks blood backward, or has a structural abnormality. Doctors interpret these findings together with symptoms and examination results.
To Measure Heart Pumping Function
A common reason for an echo is to assess left ventricular ejection fraction (LVEF), the percentage of blood in the left ventricle pumped out with each heartbeat. This measurement supports the investigation and monitoring of certain forms of heart failure. It is not the only measure of cardiovascular health.
To Monitor Known Heart Disease
A cardiologist may repeat an echo after a change in symptoms, treatment, or surgery. The interval depends on the diagnosis; routine repeat scans are not automatically necessary for every patient with stable findings.
What Are the Main Types of Echocardiogram?
Transthoracic Echocardiogram (TTE)
A transthoracic echo is the most common type. A clinician places gel and a small transducer on the chest and moves it across several positions to capture views of the heart. It is noninvasive and usually performed while the patient lies on an examination bed. The clinician may ask for brief breath holds or position changes to improve the image.
Transesophageal Echocardiogram (TEE)
A transesophageal echo uses a probe passed into the esophagus to obtain detailed images close to the heart. It may be requested when chest-wall imaging does not answer an important question, such as an issue involving a heart valve or a suspected clot. Sedation, fasting, monitoring, and an assessment of swallowing or esophageal risks may be needed. TEE is a specialist procedure, not simply a more detailed version routinely required for everyone.
Stress Echocardiogram
A stress echo compares heart images at rest and during or immediately after exercise or medication-induced stress. A clinician may request it when investigating possible problems with blood supply to the heart or other specific questions. The method and suitability depend on a patient’s symptoms and ability to exercise.
Doppler, 3D and Fetal Echocardiography
Doppler measurements are often incorporated into standard echocardiography to assess blood flow and valve function. Three-dimensional imaging may add detail for selected valve or structural problems. Fetal echocardiography is a specialized study of a baby’s heart before birth and is performed for particular pregnancy-related indications.
How Should You Prepare for an Echocardiogram?
Preparation depends on the specific type of echo. A routine transthoracic echocardiogram usually requires no fasting, and patients can generally take their usual medicines unless advised otherwise. Comfortable clothing can make the appointment easier because the upper chest needs to be accessible.
A transesophageal study generally requires fasting and instructions about sedation and transport home. A stress echo may come with specific advice about exercise, food, caffeine, and certain medications. Never stop prescribed heart medicine without instructions from the clinical team.
What Happens During a Transthoracic Echocardiogram?
The patient changes into suitable clothing or a gown and lies on an examination table. Electrodes may be attached to record the heartbeat during the scan. Ultrasound gel is applied to the chest, and the operator presses the probe gently against the skin to obtain several views.
The examination commonly takes around 30 to 60 minutes, depending on the clinical question and image quality. Mild pressure from the probe is possible, but a standard transthoracic echo is generally painless. Afterward, most patients return to normal activities immediately.
How to Understand Common Echocardiogram Results
Left Ventricular Ejection Fraction (LVEF)
Ejection fraction is a percentage that describes how much blood the left ventricle ejects with each contraction. A typical LVEF is approximately 55% to 70%, although laboratory reference ranges and interpretation vary. The American Heart Association’s explanation of ejection fraction notes that heart failure can also occur despite a normal ejection fraction.
An LVEF result should not be read in isolation. Heart size, filling function, valve abnormalities, and clinical symptoms all matter. Small differences between studies can also reflect measurement technique rather than a true change in health.
Heart Chamber Size and Wall Thickness
The report may describe whether the left or right ventricle is enlarged and whether heart muscle walls appear thickened. Findings can reflect high blood pressure, valve disease, cardiomyopathy, or other factors. A single abnormal measurement is not enough to determine the cause.
Heart Valve Findings
A report may use terms such as stenosis (narrowing) and regurgitation (leakage). A small amount of leakage can be detected in otherwise healthy hearts, while more substantial valve disease can affect blood flow and require follow-up. Severity is determined using multiple echo measurements, not just whether a term appears in the report.
Diastolic Function, Right Heart and Pericardium
Doctors can also assess how the heart relaxes and fills, estimate certain pressures, evaluate the right side of the heart, and check for fluid around the heart (pericardial effusion). These findings can be complex and should be interpreted by the referring clinician or a cardiologist.
Echocardiogram Versus ECG, Cardiac CT and Cardiac MRI
An ECG records the heart’s electrical activity and can help evaluate rhythm disturbances. An echocardiogram uses ultrasound to assess moving anatomy, pumping, and valves. A cardiac CT scan provides different information, such as coronary artery anatomy or calcium scoring, depending on the test. A cardiac MRI can provide detailed assessment of heart muscle structure and tissue in selected cases.
These investigations answer different questions and are not interchangeable. For example, a normal echo does not reliably exclude coronary artery disease, and it may not capture an intermittent rhythm problem.
When Do Heart Symptoms Need Emergency Care?
Seek emergency help for new severe chest pressure or pain, sudden major breathlessness, fainting with concerning symptoms, or signs of stroke such as facial drooping and one-sided weakness. Do not postpone emergency assessment to schedule an outpatient echocardiogram or another scan.
Frequently Asked Questions About Echocardiograms
Is an echocardiogram the same as an ECG?
No. An echo uses ultrasound to show the beating heart and blood flow, while an ECG records electrical signals. Both tests may be ordered for the same patient.
Is a standard echocardiogram painful?
A transthoracic echo is generally painless, although the probe may cause mild pressure on the chest. A transesophageal echo requires different preparation and can cause temporary throat discomfort.
How long does an echocardiogram take?
A routine transthoracic study commonly takes about 30 to 60 minutes, but the duration varies with the complexity of the examination.
Does a normal ejection fraction mean the heart is completely healthy?
No. Valve disease, problems with heart filling, and other conditions can exist despite an LVEF within the typical range.
Can an echocardiogram find blocked coronary arteries?
A resting echo cannot directly rule out blocked coronary arteries. Stress echocardiography can help investigate reduced blood supply in selected cases, while other tests may be more appropriate depending on the symptoms.
Can an echocardiogram be performed during pregnancy?
A standard transthoracic echo does not use ionizing radiation and can be performed when clinically indicated during pregnancy. The medical team selects the most suitable approach.
