1 Heart defects. 2  Many heart defects can be detected with an echocardiogram, including problems with the heart chambers, abnormal connections between the heart and major blood vessels, and complex heart defects that are present at birth. 3  Echocardiograms can even be used to monitor a baby's heart development before birth.
The test shows the size and shape of your heart and how well your heart chambers and valves work. Echo also can identify areas of poor blood flow to the heart, areas of heart muscle that aren't contracting normally, and heart muscle damage caused by lack of blood flow. Echo might be done before and after a stress test (see below). A stress echo can show how well blood is flowing through your heart.
