Two-Dimensional Echocardiogram (2D Echo)
It is a test in which ultrasound is used to picture out the heart. It is capable of displaying a cross sectional “slice” of the beating heart, including the chambers, valves and the major blood vessels that exit from the left and right part of the heart."Doppler” is a special part of the ultrasound exam that assesses blood flow (direction and velocity)
No special preparations are necessary for a standard transthoracic echocardiogram. Your doctor will ask you not to eat for a few hours beforehand if you're having a transesophageal or stress echocardiogram. If you'll be walking on a treadmill during a stress echocardiogram, wear comfortable shoes. If you're having a transesophageal echocardiogram, you won't be able to drive afterward because of the sedating medication you'll likely receive. Before your have your transesophageal echocardiogram, be sure to make arrangements to get home.
If your echocardiogram is normal, no further testing may be needed. If the results are concerning, you may be referred to a heart specialist (cardiologist) for more tests. Treatment depends on what's found during the exam and your specific signs and symptoms. You may need a repeat echocardiogram in several months or other diagnostic tests, such as a cardiac computerized tomography (CT) scan or coronary angiogram.
