Echocardiography (cardiac ECHO or simply ECHO) is a sonogram of the heart. An echocardiogram, also known as a transthroacic echocardiogram (TTE), or simply, a cardiac ultrasound, is a non-invasive procedure utilized in the management and diagnosis and follow-up of patients with any suspected or know heart diseases. Using ultrasound technology, a cardiac ultrasound creates a scan that can be recorded and viewed as a two or three-dimensional digital image of the heart.
With a cardiac ultrasound system, a trained cardiologist can promptly determine the shape,size and strength of the heart, as well as the condition of the heart valves, the lining of the heart (the endocardium), and the aorta. An echocardiogram can determine whether any chest pain or associated symptoms are related to heart disease, in addition to the detection of any blood flow abnormalities.
