Types & Benefits of Echocardiography
An echocardiogram is a test that uses high-frequency sound waves to take pictures of your heart. His common test allows your doctor to see your heart beating and pumping blood. Your doctor can use the images from an echocardiogram to identify heart disease. Echo also can pinpoint areas of the heart muscle that aren't contracting well because of poor blood flow or injury from a previous heart attack.
Doppler ultrasound shows how well blood flows through your heart's chambers and
valves. An echocardiogram uses ultrasound, or harmless sound waves, to quickly
and efficiently obtain valuable information about your heart. Our doctors
regularly use an echocardiogram or echo, when they have questions about the
size, shape, and performance of your heart and its valves.
Types
of Echocardiography
There are several types of these tests.
Transthoracic
echocardiogram
A
transthoracic echocardiogram (TTE) is the most common noninvasive type of
echocardiogram, which uses high-frequency soundwaves (ultrasound) to create a
moving picture of your heart through the chest wall.
This test is
used to examine suspected problems with the valves or chambers of the heart, as
well as the heart’s ability to pump blood.
Transesophageal
echocardiogram (TEE)
A transesophageal echocardiogram (TEE) uses echocardiography to assess the structure
and function of the heart. During the procedure, a transducer sends out
ultrasonic sound waves. Being overweight or having certain lung diseases can
interfere with images of the heart when the transducer is placed on the chest
wall.
Stress
echocardiogram
Stress echocardiography is a test that uses ultrasound
imaging to show how well your heart muscle is working to pump blood to your
body. It is most often used to detect a decrease in blood flow to the heart
from narrowing in the coronary arteries.
Intravascular
ultrasound
Benefits
of Echocardiography
Once
the technician has obtained the images, it usually takes 20 to 30 minutes to
perform the measurement. If you have
a transesophageal echo, you may be watched for a few hours at the doctor's
office or hospital after the test. Your throat might be sore for a few hours
after the test. These parts include the heart valves, the septum, and the
walls of the heart chambers. Doppler ultrasound shows the movement of blood
through your heart. This will solve these problems including:
·
Pumping strength
·
Changes in your heart
size
·
Damage to the heart
muscle
·
Valve problems
·
Heart defect
After
the Echocardiography
You
usually can go back to your normal activities right after having
echocardiography. If your echocardiogram is normal, no further testing may be
needed. If the results are concerning, you may be referred to a doctor trained
in heart conditions for
more tests.
Your doctor will talk with you after looking at your echo
pictures and discuss what the pictures show. The doctor will explain the procedure and offer you the opportunity to ask
questions about the procedure. Generally, no prior preparation, such as fasting
or sedation is required. The
results may reveal abnormalities such as:
- damage to the heart muscle
- valve problems
- problems with pumping function
- Determine the need for more
tests
- Diagnose heart problems
Risk
of Echocardiography
Echocardiography has no risks. You may feel some discomfort from the
transducer being held very firmly against your chest. The firmness is necessary
to produce the best images of your heart.
