What is 2D Echocardiography?
A 2D echocardiogram, often referred to as a 2D echo test, is a non-invasive imaging technique used to evaluate the heart's structure and function. The diagnostic test uses high-frequency waves to produce moving images of the heart.
2D echocardiography, unlike a standard ultrasound, a 2D echo provides cross-sectional views, allowing doctors to visualize the heart's chambers, valves, and major blood vessels in motion. This detailed view helps evaluate how well your heart is pumping and if the valves are functioning correctly. The images help doctors assess various cardiac abnormalities, including problems with the heart's valves, chambers, and blood flow. The "2D" aspect refers to the two-dimensional images created, which provide a clear, detailed view of the heart.

What is a 2D Echo Test?
A 2D echo test, also known as a 2D echo procedure, is a painless and non-invasive diagnostic procedure. The test is also referred to as a "transthoracic echocardiogram" (TTE), where a small device called a transducer is placed on the chest to transmit sound waves. The sound waves bounce off the heart and return to the transducer, which then converts them into images that a cardiologist can interpret. The test is crucial for assessing heart health and identifying potential problems.
2D Echo vs ECG: Know The Difference
While both a 2D echo and an ECG (electrocardiogram) are used to evaluate the heart, they provide different information. An ECG measures the electrical activity of the heart, while a 2D echo provides images of the heart's structure and function. They are often used together to provide a more complete assessment of heart health.
What Are the Types of 2D Echo Tests?
There are different types of 2D echo tests, each designed to assess specific aspects of the heart's health. Below are the common types:
Transthoracic Echocardiogram (TTE):
The most commonly used 2D echo test type is the transthoracic echocardiogram (TTE), which involves placing a transducer on the chest. It provides a general view of the heart's size, function, and structure. This test is painless and non-invasive.
Transesophageal Echocardiogram (TEE):
A transesophageal echocardiogram (TEE) provides more detailed images of the heart's structures, especially for patients who cannot get clear images through a standard TTE. In a TEE, the transducer is passed down the throat to obtain close-up images of the heart from within the esophagus.
This type of 2D echo is performed while you are exercising (typically on a treadmill or stationary bike) or after being given medication that simulates exercise. It helps doctors evaluate how your heart responds to stress and can detect conditions like coronary artery disease. A fetal 2D echo is a specialized type of echocardiogram used to examine the heart of an unborn baby.
Why Do I Need a 2D Echo Test?
The cardiologists may recommend a 2D echo test in case of apparent symptoms of heart-related issues such as chest pain, shortness of breath, dizziness, or irregular heartbeats. Doctors may also recommend a 2D echo test to assess the effectiveness of heart treatments or evaluate conditions like heart murmurs, hypertension, or coronary artery disease. Here are some common reasons why you may need a 2D echo test to:
Assess chest pain & Identify congenital heart defects.
Determine the heart's pumping strength (ejection fraction)
Evaluate the size and shape of the heart's chambers
Evaluate heart murmurs
Check for congenital heart defects
Assess the function of the heart valves
Monitor the effectiveness of heart treatments
Investigate unexplained shortness of breath or fatigue
Follow-up after a heart attack
What Are The Benefits of Undergoing a 2D Echo Test?
A 2D echo test is a widely used diagnostic procedure that provides valuable insights into the health of the heart. By using sound waves to create real-time images, it helps doctors assess the heart’s structure and function. This non-invasive test plays a crucial role in monitoring and diagnosing various heart-related conditions for better overall care:
Non-invasive and painless:
There are no incisions or injections involved and therefore the test is completely painless.

The high-frequency waves provide accurate images of the heart which allows for accurate assessment of heart structure and function.
Relatively quick and easy:
A 2D echo test is a quick diagnostic test that is generally completed within an hour.
Since this test uses high-frequency sound waves, there is no exposure to radiation, unlike X-rays.
Detect other cardiac illnesses:
Helps identify congenital issues like holes in the heart or abnormal valve development and other cardiac illnesses.
How To Prepare For The 2D Echo Test?
The preparation for a 2D echo test is minimal. You can eat, drink, and take your medications as usual. However, for a transesophageal echocardiogram (TEE), you will likely be asked to fast for several hours before the procedure. The cardiologist will recommend wearing a gown to facilitate access to your chest area. Ask your cardiologist for a PIL (patient information leaflet) for customized instructions based on your preferences and choices.
What Happens During The 2D Echo Test?
The procedure for a 2D echo test typically takes around 30 minutes. While the whole test is painless, the patient might feel a cooling sensation on the skin due to the gel. There is typically no recovery time and the patient can go home right after the test. Here's what to expect during your 2D echo test:
The patient is asked to lie on an examination table.
A gel is applied to the chest to help the transducer move smoothly.
The technician or cardiologist moves the transducer over the chest to capture images of your heart.
In some cases, you may be asked to change positions or hold your breath briefly to get clearer images.
2D Echo Report Normal Range and 2D Echo Normal Values
A 2D echo test provides valuable insights into the heart’s structure and functioning. The normal range and values vary based on factors like age, gender, and individual health conditions. However, there are general reference values that are typically considered normal for most adults. These values help cardiologists assess the health of the heart’s chambers, valves, and blood flow.
However, please note that the values mentioned are for reference purposes, and slight variations can be normal. In case the results lie outside the normal range, get in touch with a cardiologist for further evaluation to determine the cause of any abnormalities.
Below is a table summarizing the typical 2D echo normal values:
Parameter | Normal Range |
Left Ventricular End-Diastolic Dimension (LVIDd) | 4.6 – 5.9 cm |
Left Ventricular End-Systolic Dimension (LVIDs) | 2.9 – 4.0 cm |
Left Atrial Diameter | 2.7 – 4.0 cm |
Aortic Root Diameter | 2.0 – 3.7 cm |
Mitral Valve Area | 4.0 – 6.0 cm² |
Tricuspid Valve Annulus | 2.2 – 3.0 cm |
Ejection Fraction (EF) | 55% – 70% (normal heart pumping ability) |
Peak Velocity across Aortic Valve | < 1.7 m/s (normal blood flow) |
Pulmonary Artery Pressure | < 25 mmHg |
Right Ventricular Systolic Pressure (RVSP) | < 35 mmHg |
Interventricular Septal Thickness (IVS) | 0.6 – 1.0 cm |
2D Echo Test in Pregnancy:
A 2D echo test can be safely performed during pregnancy if needed to evaluate the mother's heart health or to assess the fetal heart (fetal 2D echo). It uses sound waves, which are considered safe for both mother and baby. For the baby, a fetal 2D echo checks the heart’s structure and function, allowing doctors to detect any congenital heart defects or other issues early. This test can assess the baby’s heart rate, rhythm, and blood flow, helping ensure the heart is developing properly.
For mothers with heart conditions or high-risk pregnancies, the 2D echo test is also used to monitor the health of their heart, looking at valve function and blood flow. The main benefits of a 2D echo test during pregnancy are that it is safe, can catch potential issues early, and provides reassurance to parents. If any problems are found, doctors can take steps to address them, leading to better care for both the mother and baby.
