Echocardiography is a painless diagnostic that uses sound waves to create moving images of your heart. The images represent the size and shape of your heart. They also show how your heart's chambers and valves are doing.
Due to a lack of blood supply or injury from a previous heart attack, echo can detect sections of the heart muscle that aren't contracting properly. Doppler ultrasonography is a sort of echo that indicates how well blood flows through your heart's chambers and valves. Possible blood clots inside the heart, fluid build-up in the pericardium (the sac surrounds the heart), and aortic issues can all be detected with an echo. The primary artery that transports oxygen-rich blood from your heart to your body is the aorta.
