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.
Also, echocardiograms may be safer since they use sound waves instead of radiation. Another key benefit of an echocardiogram is that the test captures moving images of the heart, allowing the cardiologist to see how the heart pumps blood and how the valves function.
