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 echocardiogram can evaluate the size, the function of the heart muscle as well as the heart valves. Patients who have a history of heart attacks may have weak heart muscles or an area of the heart muscle that does not contract effectively. An echocardiogram may also demonstrate other reasons outside of the heart that may be causing these symptoms.
