How to Read an Echocardiogram Report? Normal vs Abnormal Echocardiogram

A standard echocardiogram provides key insights into the heart’s health. In a standard report, the walls of the arteries measure less than 1.5 cm, indicating normal blood flow. The heart's pumping action will be smooth, with no signs of obstruction or difficulty. Additionally, the heart’s size and mass will fall within the typical range, neither too large nor too small.

‍

Expected results also show healthy heart valves and chambers, with normal heart wall movement, suggesting no significant cardiovascular issues. An abnormal echocardiogram reveals several concerning signs. The walls of the arteries may be thicker than 1.5 cm, which can restrict blood flow and impact the heart's efficiency. The heart's movement may deviate from its usual patterns, possibly indicating dysfunction or a structural issue.

‍

The heart's size or mass could be abnormal, either enlarged or smaller than average, reflecting potential health problems. Abnormalities in the heart’s physical state often point to underlying issues such as heart disease, valve disorders, or heart failure. While some abnormalities in an echocardiogram may be minor and pose minimal risk, others can signal more serious heart conditions. 

‍

What Is an Echocardiogram?

An echocardiogram is a diagnostic imaging test that uses ultrasound technology to create detailed images of the heart’s structure and movement. During the procedure, a handheld transducer is placed on the chest, sending high-frequency sound waves to capture images of the heart’s valves and chambers. This allows healthcare providers to assess the heart's pumping function and detect any potential issues. 

‍

This non-invasive test is commonly used to evaluate heart valve problems, assess heart failure, detect congenital disabilities, or investigate symptoms like chest pain and shortness of breath. Accurate assessment of the echocardiogram results is vital for early diagnosis of heart conditions, enabling timely and appropriate treatment to improve patient outcomes.

‍

Why Is an Echocardiogram Done?

An echocardiogram is primarily performed to assess the heart's structure and function. It provides detailed images of the heart chambers, valves, and blood flow, allowing doctors to evaluate how well the heart is pumping and how blood circulates through the heart. A healthcare provider may recommend an echocardiogram if a patient experiences symptoms like chest pain, shortness of breath, or fatigue, which could indicate underlying heart issues.

‍

It is also used to monitor existing heart conditions, such as heart valve disease, heart failure, or congenital heart defects, to guide treatment decisions and track disease progression. This diagnostic tool offers valuable insights into the heart’s health, enabling timely intervention and management.

‍

How Is an Echocardiography Performed?

Various imaging techniques are employed to assess the heart's structure and function, with each method offering unique advantages based on the patient's condition and the specific information needed. These techniques provide critical insights into blood flow, heart muscle movement, and the overall health of the heart.Common techniques include 2D and 3D ultrasound, Doppler and Color Doppler ultrasound, strain imaging, and contrast imaging.

‍

Each approach helps healthcare providers evaluate different aspects of cardiac health, from the speed of blood flow to early signs of heart disease, ensuring accurate diagnosis and treatment planning. Several imaging techniques are utilized to visualize the heart, with the choice of method dependTwo-dimensional (2D) ultrasound is the most commonly used method, producing 2D images that appear as cross-sectional "slices" of the heart. 

‍

• Three-dimensional (3D) ultrasound provides a more accurate representation of the heart. This technique assesses how effectively it pumps blood.

• Doppler ultrasound evaluates the speed and direction of blood flow within the heart.

• Color Doppler ultrasound is a variation of Doppler imaging that uses color coding to highlight the direction and flow of blood, providing a clearer view of circulation.

• Strain imaging assesses myocardial deformation, detecting subtle changes in heart muscle movement that may indicate early signs of heart disease.

• Contrast imaging involves the injection of a contrast agent into the bloodstream, enhancing the visibility of the heart's structures in the images.

‍

What is a Normal Echocardiogram?

A normal echocardiogram shows that the walls of your arteries are thinner than 1.5 cm, indicating healthy blood flow without obstruction. The heart's pumping action will be regular, functioning efficiently, with no signs of difficulty or blockages.

‍

Additionally, a normal echocardiogram will reflect a heart size and mass within the typical range, neither enlarged nor smaller than average. These findings suggest that the heart is functioning well, with healthy heart valves and chambers and no significant cardiovascular issues present.

‍

What Is an Abnormal Echocardiogram?

An abnormal echocardiogram will show the walls of your arteries thicker than 1.5 cm, which can restrict blood flow and affect heart function. This may lead to difficulties in how the heart pumps blood.

‍

The heart’s movement may also deviate from its normal patterns, and the size or mass of the heart could be larger or smaller than average. These irregularities indicate potential cardiovascular issues and may suggest the need for further evaluation or treatment to address the underlying concerns.

‍

The Key Differences Between Normal vs Abnormal Echocardiogram

The key indicators to look for include thin artery walls, typically less than 1.5 cm, and smooth, unobstructed heart movement. The heart's size and mass should be within the typical range, with normal pumping function. There should be no abnormal fluid accumulation around the heart or irregularities in the heart chambers or valves. On the other hand, an abnormal echocardiogram shows thicker artery walls, often greater than 1.5 cm, suggesting restricted blood flow.

‍

The heart’s movement may be erratic or show signs of dysfunction. The size and mass of the heart could be either enlarged or smaller than average, pointing to possible conditions like cardiomyopathy or heart failure. Additionally, the presence of abnormal fluid around the heart or structural changes in the valves or chambers often signals underlying heart disease, requiring further diagnostic investigation.

‍

When Can One Get an Abnormal Echocardiogram?

An abnormal echocardiogram can occur when there are issues with the heart’s structure or function. It may indicate heart valve disease, where the valves do not open or close properly, affecting blood flow. Cardiomyopathy, a condition where the heart muscle becomes weakened, can also show up on the echocardiogram.

‍

Additionally, an abnormal result may suggest pericardial effusion, which is fluid accumulation around the heart, or other heart abnormalities, such as congenital disabilities or arrhythmias, requiring further testing and treatment.

‍

Abnormal echocardiograms can be the result of the following cases:

• Congenital heart disease

• Cardiomyopathy

• Infective endocarditis

• Pericardial effusion

• Valve disease

• Aortic aneurysm

• Blood clots

• Cardiac tumour

‍

What Are the Risk Factors of an Echocardiogram?

Echocardiograms are generally considered safe, using harmless sound waves with no known risks or exposure to X-rays. However, depending on the type of echocardiogram performed, some mild discomfort or risks may occur. For a standard transthoracic echocardiogram, the ultrasound wand pressing against your chest may cause slight discomfort. If contrast dye is used, reactions such as backaches, headaches, or rashes can occur, though they are rare.

‍

For a transesophageal echocardiogram (TEE), additional risks include a sore throat, difficulty swallowing, or, in rare cases, esophageal perforation. A stress echocardiogram may cause temporary side effects, such as irregular heartbeats or low blood pressure, though serious complications like heart attack are extremely uncommon.

‍

Standard Transthoracic Echocardiogram (TTE): 

A standard transthoracic echocardiogram is generally safe, but some risks include mild discomfort from the ultrasound probe pressure, skin irritation from the gel, or anxiety in some patients. Rarely, it can trigger arrhythmias in sensitive individuals. Overall, complications are minimal, making it a low-risk diagnostic procedure.

‍

The Contrast Dye

The contrast dye used in echocardiography enhances imaging but carries some risks. These include allergic reactions, kidney damage (especially in those with pre-existing kidney conditions), and potential interference with blood flow. Rarely, contrast agents can cause breathing difficulties or other side effects, but such complications are uncommon and typically manageable. 

‍

Used in some echocardiograms may cause mild reactions, such as:

• Backaches, headaches, or rashes.

• Reactions typically occur immediately during the test, and severe allergic reactions are rare.

‍

Transesophageal Echocardiogram (TEE):

A transesophageal echocardiogram (TEE) carries risks such as throat discomfort, aspiration, or injury to the esophagus. Rare complications include bleeding, infection, or an abnormal heart rhythm. Additionally, sedation required for the procedure may cause respiratory or cardiovascular issues in some patients, though these are infrequent and typically managed effectively.

‍

• Difficulty swallowing

• Weak or scratchy voice

• Muscle spasms in the throat or lungs

• Minor bleeding in the throat area

• Injury to teeth, gums, or lips

• Esophageal perforation (hole in the esophagus)

• Irregular heartbeats (arrhythmias)

• Nausea from medications

‍

Stress Echocardiogram

A stress echocardiogram involves minimal risks, including temporary chest pain, shortness of breath, or dizziness during exercise or medication-induced stress. Rarely, it may trigger abnormal heart rhythms, heart attack, or fainting. However, the procedure is generally safe when conducted under careful supervision by trained medical professionals.

‍

• Fast or irregular heartbeat

• Flushing feeling

• Low blood pressure

• Allergic reactions

‍

How to Prepare for an Echocardiogram

The preparation for an echocardiogram depends on the type of test being performed. For a standard transthoracic echocardiogram, there is typically no need for special preparation, and you can eat and drink as usual before the procedure. However, if you are having a transesophageal echocardiogram (TEE), you may be asked to fast for a few hours before the test. It's important to follow your healthcare provider's specific instructions regarding preparation for a TEE.

‍

Additionally, you should inform your healthcare provider about any medications you are taking, including over-the-counter drugs. For a TEE, you may need to arrange a ride home, as you will receive medication to relax you during the procedure and will not be able to drive afterward. Be sure to confirm with your provider whether you can take your regular medications before the test.
