Purpose: An echocardiogram is performed for the following reasons:
- Assessment of the overall function of the heart
- Check the progress of valve diseases over time
- Check the reasons for an abnormal electrocardiogram or ECG (electrical activity of the heart)
- Check the effectiveness of medical or surgical treatments
- Diagnose the presence of heart diseases, like blocked or leaky heart valves, enlargement of the heart chambers, stiffening or weak pumping of the heart muscle
- Locating tumors or blood clots
- Identification of congenital (present at birth) abnormalities of the heart
Symptoms: The symptoms that indicate the need for an echocardiogram are:
- Shortness of breath
- Irregular heartbeat (Arrhythmia)
- Swelling of legs
- High blood pressure or low blood pressure
- Abnormal electrocardiogram (ECG) results
- Heart murmurs (unusual sounds between heartbeats)
Echocardiography is required in the following conditions:
- Heart attack
- Heart failure
- Enlarged heart (cardiomegaly)
- Endocarditis
- Cardiomyopathy
- You will be asked to remove your clothes from the waist up.
- You will then be instructed to lie on a table on your back, or on your left side.
- A dye or saline solution may be injected into your veins, to make the heart more defined on an echocardiogram.
In case of a transthoracic echocardiogram, the procedure is performed as follows:
- A gel is applied to the chest region.
- A transducer is moved around the chest to obtain the different images of the heart.
- During the procedure, you may be asked to change positions, or hold a deep breath, or take a deep breath.
- The transducer may be pressed into the chest to obtain a better image of the heart.
In case of a transesophageal echocardiogram, the procedure is performed as follows:
- It helps in obtaining a more detailed image of the heart than a transthoracic echocardiogram.
- You may receive a mild sedative to help you in relaxing the muscles in the throat region, and local anesthesia to numb the gag reflex.
- The images of the heart are recorded as the transducer is moved around the esophagus.
- You will not feel the transducer or the tube in the food pipe after the initial swallowing of the probe.
An echocardiogram is generally a safe procedure. A few complications that could be associated with echocardiography include:
- Discomfort during electrode removal
- Allergic reaction to the contrast
- Esophageal irritation
- Perforation of the esophagus
- Soreness in the throat
- Drowsiness, in using a sedative
- Irregular heartbeat causing a heart attack (stress echocardiogram)
- You can resume your daily activities immediately after a transthoracic echocardiogram.
- If you have a transesophageal echocardiogram, you will need to stay in the hospital for a couple of hours after the test.
- You may have a sore throat for a couple of hours after a transesophageal echocardiogram.
- If you receive a sedative before the test, you should not drive for a couple of hours after the echocardiogram.
- You will most probably be able to resume your normal exercise and diet regime immediately after the procedure.
