An echocardiogram is an ultrasound of your heart. It uses sound waves, not radiation, to create moving pictures of your heart’s chambers, valves, and walls. When you get the results, you are looking at measurements and descriptions that tell your doctor how well your heart is pumping, how your valves are working, and whether the structure of your heart looks normal.
Reading your own results starts with understanding a few key numbers and terms. The most common measurement is ejection fraction, which shows how much blood your heart pumps out with each beat. Normal is generally between 50% and 70%. But that number is only one piece of the picture. Your report will also describe valve function, chamber sizes, wall thickness, and how well your heart muscle relaxes between beats.
What Is an Echocardiogram and Why Did My Doctor Order One?
An echocardiogram is a painless test that takes about 30 to 60 minutes. A technician places a wand on your chest and sometimes your neck. The wand sends sound waves that bounce off your heart structures and create images on a screen.
Doctors order this test for many reasons. You may have had chest pain, shortness of breath, an abnormal heart rhythm, or a heart murmur. Or your doctor may want to check how well your heart is working after a heart attack or before starting certain treatments.
There are different types of echocardiograms. A transthoracic echocardiogram is the standard test done on your chest. A transesophageal echocardiogram involves a scope passed down your throat to get clearer pictures of certain structures, especially the back of the heart and some valves. A stress echocardiogram combines the ultrasound with exercise or medication to see how your heart responds under stress.
The report you receive will describe what the technician saw and what the interpreting physician concluded. It is not a diagnosis on its own. Your doctor uses it along with your symptoms, exam, and other tests.
What Is Ejection Fraction and What Do the Numbers Mean?
Ejection fraction (EF) is the percentage of blood in your left ventricle that gets pumped out with each heartbeat. The left ventricle is the main pumping chamber of your heart. It sends blood to your entire body.
A normal ejection fraction is generally between 50% and 70%. If your EF is below 50%, it may indicate that your heart is not pumping as well as it should. An EF between 41% and 49% is considered mildly reduced. An EF of 40% or below is classified as reduced ejection fraction, sometimes called heart failure with reduced ejection fraction.
An EF above 70% is not necessarily better. In some cases, a high EF can mean the heart muscle is stiff and has trouble filling properly. This is called heart failure with preserved ejection fraction, or HFpEF. The heart pumps out a normal percentage but cannot relax enough to fill with blood between beats.
Your EF can change over time. It may improve with treatment or worsen if your heart condition progresses. A single number is a snapshot, not a permanent label.
It is also important to know that EF is an estimate. Different technicians and different machines can produce slightly different measurements. A change of a few percentage points between tests may not be meaningful.
How Do I Understand Valve Findings in My Report?
Your echocardiogram report will describe each of your four heart valves. The valves act like doors that open and close to keep blood flowing in the right direction.
The two most common valve problems are stenosis and regurgitation. Stenosis means the valve is too narrow and does not open fully. Regurgitation means the valve does not close tightly and blood leaks backward.
Valve findings are usually graded as mild, moderate, or severe. Mild regurgitation is common and often not a concern. Moderate or severe findings may need more attention. The report may also include specific measurements like valve area or pressure gradients.
For example, a mean gradient across the aortic valve measures how much pressure builds up because the valve is narrow. A higher gradient means more obstruction. Your doctor will interpret these numbers in the context of your symptoms and overall health.
Some valve problems are watched over time with repeat echocardiograms. Others may require medication or a procedure to repair or replace the valve. The decision depends on many factors, not just the echo result.
What Do Chamber Size and Wall Thickness Tell Me?
Your report will include measurements of your heart’s four chambers: the left and right atria, and the left and right ventricles. It will also measure the thickness of your heart walls.
Enlarged chambers can be a sign of several conditions. An enlarged left ventricle may result from high blood pressure, valve disease, or a weakened heart muscle. An enlarged left atrium can be associated with atrial fibrillation or other heart problems.
Wall thickness is measured in millimeters. The normal range for the left ventricular wall is generally between 6 and 12 millimeters, though this can vary based on body size and sex. Thicker walls can mean the heart is working harder than it should, often because of high blood pressure or a condition called hypertrophic cardiomyopathy.
These measurements help your doctor understand the pattern of your heart disease. They also help guide treatment decisions. For example, if your left ventricle is enlarged and your blood pressure is high, controlling blood pressure becomes especially important.
What Does Diastolic Function Mean on My Report?
Diastolic function describes how well your heart relaxes and fills with blood between beats. This is different from systolic function, which is how well your heart squeezes.
Your report may describe diastolic function as normal, mildly impaired, moderately impaired, or severely impaired. It may also include specific measurements like the E/A ratio or tissue Doppler values.
Diastolic dysfunction is common, especially in older adults and people with high blood pressure, diabetes, or obesity. It can cause symptoms like shortness of breath, especially with activity, even when ejection fraction is normal.
This is the same condition mentioned earlier as HFpEF. The heart pumps out a normal percentage of blood but has trouble filling. Treatment focuses on managing underlying conditions and reducing symptoms.
Diastolic function is more difficult to measure accurately than ejection fraction. There is more variability between labs and technicians. Your doctor will interpret these findings alongside your symptoms and other test results.
What Other Findings Might Appear on My Report?
Echocardiogram reports often include additional observations. These may or may not be significant.
- Pericardial effusion: Fluid around the heart. Small amounts are often harmless. Larger amounts can affect heart function.
- Thrombus: A blood clot inside a heart chamber. This needs medical attention because it can travel to the brain or other organs.
- Vegetation: A mass on a valve, which can indicate infection. This requires prompt evaluation.
- Pulmonary artery pressure: An estimate of pressure in the arteries of your lungs. Elevated pressure can be a sign of heart or lung disease.
- Inferior vena cava size: This can give clues about your fluid status and right heart function.
Not every finding requires action. Some are incidental and harmless. Others need follow-up testing or treatment. Your doctor will tell you which findings matter for your situation.
How Accurate Is an Echocardiogram?
Echocardiography is a well-established imaging method. It is widely used and has been studied for decades. For many measurements, especially ejection fraction and chamber size, it provides reliable information that guides clinical decisions.
However, it has limitations. Image quality can vary based on your body size, lung disease, or chest shape. The technician’s skill matters. And some measurements, like diastolic function, have more variability than others.
An echocardiogram is not perfect. It is one tool among many. Your doctor uses it with your history, physical exam, and other tests like electrocardiograms, stress tests, or cardiac MRI when needed.
If your results seem confusing or concerning, ask your doctor to explain them in plain language. You are entitled to understand your own health information. Bring a list of questions. Ask what the findings mean for your treatment and what comes next.
Frequently Asked Questions
What is a normal ejection fraction on an echocardiogram?
A normal ejection fraction is generally between 50% and 70%. Values below 50% may indicate reduced pumping function, while values above 70% can sometimes suggest a stiff heart muscle.
Can I read my echocardiogram report without a doctor?
You can read the numbers and terms, but interpreting them requires medical training and context. A finding that looks alarming on paper may be harmless in your specific situation, and vice versa.
What does mild regurgitation mean on an echo report?
Mild regurgitation means a small amount of blood is leaking backward through a valve. This is common and often not a health concern, but your doctor will decide if it needs monitoring.
How often should I get an echocardiogram?
The frequency depends on your heart condition and your doctor’s recommendations. Some people need one every few months, while others may go years between tests.
