An echocardiogram is a non-invasive test that uses ultrasound waves to create images of the heart. Doctors use it to assess heart structure, function, and blood flow, helping diagnose conditions like heart valve disorders, congenital defects, and heart failure. It is safe, painless, and requires little to no preparation. This test provides real-time visuals, allowing early detection and effective treatment planning for heart diseases. Let us understand its types, usage, and procedure.

Types of Echocardiogram

An echocardiogram (echo) is a diagnostic test that uses ultrasound waves to create images of the heart, helping doctors assess its structure and function. There are different types of echocardiograms, each serving a specific purpose based on the patient’s condition.

1. Transthoracic Echocardiogram (TTE)

The transthoracic echocardiogram (TTE) is the most common and non-invasive type of echocardiogram. During the procedure, a handheld probe (transducer) is placed on the chest to capture detailed images of the heart. This test is primarily used to assess the heart’s chambers, valves, and blood flow, helping diagnose various heart conditions. One of its key advantages is that no special preparation is required, making it a simple and convenient diagnostic tool.

2. Transesophageal Echocardiogram (TEE)

The transesophageal echocardiogram (TEE) is a more detailed imaging technique used when a standard transthoracic echocardiogram (TTE) does not provide clear images due to factors like obesity, lung disease, or chest deformities. In this procedure, a thin probe is inserted through the oesophagus to capture clearer and more precise images of the heart. Since the oesophagus is located close to the heart, this method allows for better visualisation of heart structures. To ensure comfort, sedation is administered, and patients are required to fast for a few hours before the procedure.

3. Contrast Echocardiogram

A contrast echocardiogram is a specialised imaging technique in which a contrast agent (a special dye) is injected into the bloodstream to enhance the clarity of heart images. This method is particularly useful for detecting small defects, abnormal blood flow, or heart muscle damage that may not be visible on a standard echocardiogram. It is often used to evaluate heart function after a heart attack, providing detailed insights into cardiac health and assisting in accurate diagnosis and treatment planning.

4. Stress Echocardiogram

A stress echocardiogram is performed before and after physical exertion, such as on a treadmill or bicycle, or with medication that simulates exercise. It helps detect coronary artery disease (CAD) and assesses how well the heart respond to stress. This test is particularly useful for evaluating symptoms like chest pain, shortness of breath, or irregular heartbeat, aiding in the early detection of heart conditions.

5. Doppler Echocardiogram

A Doppler echocardiogram is a specialised technique used alongside other echocardiograms to measure blood flow and heart valve function. It helps diagnose valve disorders, congenital heart defects, and abnormal blood circulation, identifying issues such as regurgitation (backward blood flow) or valve narrowing, which can affect heart efficiency.

6. Foetal Echocardiogram

A foetal echocardiogram is performed on pregnant women between 18-24 weeks of pregnancy to assess the baby’s heart. It helps detect congenital heart defects before birth, allowing for early diagnosis and planning. Using ultrasound waves, this test is completely safe for both the mother and baby.

7. 3D Echocardiogram

A 3D echocardiogram provides detailed three-dimensional images of the heart’s structure and movement, offering enhanced visualisation. It is particularly useful for complex valve assessments, congenital heart defects, and surgical planning. This advanced technique can be performed as either a transthoracic (TTE) or transesophageal (TEE) echocardiogram for more precise evaluation.

Usage of Echocardiogram

The echocardiogram uses are as follows:

Diagnosing heart conditions (valve diseases, cardiomyopathy, congenital defects)
Evaluating heart valves (stenosis, regurgitation)
Guiding surgical and interventional procedures
Assessing heart damage after a heart attack
Monitoring congenital heart defects
Assessing heart function (ejection fraction, pumping efficiency)
Detecting coronary artery disease (CAD)

Procedure of Echocardiogram

The echocardiogram procedure varies based on the type being performed but generally follows these steps:

Step 1: Preparation

Most echocardiograms require no special preparation, except for a transesophageal echocardiogram (TEE), which requires fasting for a few hours.

Step 2: Electrode Placement

Small electrodes may be placed on the chest to monitor heart activity during the test.

Step 3: Gel Application

A special gel is applied to the chest to help the ultrasound probe (transducer) capture clear images.

Step 4: Image Capture

The technician moves the transducer over the chest (transthoracic echocardiogram) or inserts a thin probe through the oesophagus (TEE) to obtain detailed heart images.

Step 5: Doppler and Contrast (If Needed)

Additional techniques like Doppler echocardiography (to assess blood flow) or a contrast agent (for clearer images) may be used.

Procedure Completion: The procedure usually takes 30-60 minutes, and patients can resume normal activities immediately, except in cases requiring sedation.

Did You Know?

Did you know that a special type of echocardiogram, called a contrast echocardiogram, uses tiny bubbles to detect heart defects? A harmless saline solution with microbubbles is injected into a vein, and if the bubbles pass from one side of the heart to the other, it could indicate a small hole, such as a patent foramen ovale (PFO), that may otherwise go unnoticed.
While echocardiograms primarily assess heart function, a transesophageal echocardiogram (TEE) can provide a clearer view of the heart’s chambers, helping doctors detect hidden blood clots in the left atrium. This is especially crucial for people with atrial fibrillation, where undetected clots could increase the risk of stroke.

Myths and Facts

Let's debunk some common myths and uncover the facts related to Echocardiograms:

Myth 1: An echocardiogram is the same as an electrocardiogram (ECG).
Fact: Although both tests assess heart function, they are different. An ECG records the heart’s electrical activity, while an echocardiogram provides real-time images of the heart’s structure and movement using ultrasound technology.

Myth 2: The test is painful and invasive.
Fact: A standard transthoracic echocardiogram (TTE) is non-invasive and painless. A technician places a probe on the chest with gel to capture images of the heart. While transesophageal echocardiograms (TEE) involve inserting a probe through the throat, sedation is used to ensure comfort.

Fact 3: The abnormal echocardiogram results always indicate a severe heart condition.
Fact: Not all abnormalities mean serious heart disease. Some variations are harmless or related to temporary factors like hydration levels, mild valve changes, or age-related differences. A doctor will interpret the results based on your symptoms and medical history.
