      Echocardiography



      GENERAL INFO:


      What Is Echocardiography?

      Echocardiography (EK-o-kar-de-OG-ra-fee) is a painless test that uses sound waves to create images of your heart. It provides your doctor with information about the size and shape of your heart and how well your heart’s chambers and valves are working.

      The test also can identify areas of heart muscle that aren’t contracting normally due to poor blood flow or injury from previous heart attack(s). In addition, a type of echocardiography called Doppler ultrasound shows how well blood flows through the chambers and valves of your heart. Echocardiography can detect possible blood clots inside the heart, fluid buildup in the sac around the heart (pericardium), and problems with the aorta (the main artery that carries oxygen-rich blood out of the heart).

      Who Needs Echocardiography?

      Your doctor may recommend echocardiography if you’re suffering from signs and symptoms of heart problems. For example, symptoms such as shortness of breath and swelling in the legs can be due to weakness of the heart (heart failure), which can be seen on an echocardiogram.

      Doctors also use echocardiography to provide information on:

      The size of your heart. An enlarged heart can be the result of high blood pressure, leaky heart valves, or heart failure.
      Heart muscles that are weak and aren’t moving (pumping) properly. Weakened areas of heart muscle can be due to damage from a heart attack. Or weakening could mean that the area isn’t getting enough blood supply, which can be due to coronary artery disease.

      Problems with your heart’s valves. Echocardiography can show whether any of the valves of your heart don’t open normally or don’t form a complete seal when closed.

      Abnormalities in the structure of your heart. Echocardiography can detect a variety of heart abnormalities, such as a hole in the septum (the wall that separates the two chambers on the left side of the heart from the two chambers on the right side) and other congenital heart defects (structural problems present at birth).

      The aorta. Echocardiography is commonly used to assess and detect problems with the aorta such as aneurysm (abnormal bulge or “ballooning” in the wall of an artery).

      Blood clots or tumors. If you have had a stroke, echocardiography might be done to check for blood clots or tumors that may have caused it.
      Doctors also use echocardiography to see how well your heart responds to certain heart treatments, such as treatment for heart failure.

      Types of Echocardiography

      There are several different types of echocardiography-all use sound waves to create images your heart. This is the same technology that allows doctors to see an unborn baby inside a pregnant mother. Unlike x rays and some other tests, echocardiography doesn't involve radiation.


      Transthoracic Echocardiography


      Transthoracic (tranz-thor-AS-ik) echocardiography is the most common type of echocardiogram test. It's painless and noninvasive. "Noninvasive" means that no surgery is done and no instruments are inserted into your body.

      This type of echocardiography involves placing a device called a transducer on your chest that sends special sound waves, called ultrasound, through your chest wall to your heart. Ultrasound waves can't be heard by the human ear. As the ultrasound waves bounce off the structures of your heart, a computer in the echocardiography machine converts them into pictures on a screen.

      Stress Echocardiography


      This is an echocardiography test that's done as part of a cardiac stress test. During a cardiac stress test, you exercise or take medicine (given by your doctor) to make your heart pump harder and beat faster. Some heart problems, such as coronary artery disease, are easier to diagnose when the heart is beating fast and pumping hard.


      Transesophageal Echocardiography


      With standard transthoracic echocardiography, it can be difficult to see the aorta and certain other parts of your heart. If your doctor needs a better look at these areas, he or she may recommend transesophageal (tranz-ih-sof-uh-JEE-ul) echocardiography.

      In this test, the transducer is attached to the end of a flexible tube that's guided down your throat and into your esophagus (the tube leading from your mouth to your stomach) to get a more detailed image of your heart.

      Fetal Echocardiography


      This type of echocardiography is used to look at an unborn baby's heart. A doctor may recommend this test to check the baby for heart problems. Fetal echocardiography is commonly performed during pregnancy at about 18 to 22 weeks.
