A Transthoracic Echocardiogram is a diagnostic procedure that demonstrates the heart’s function using ultrasound technology. Transthoracic Echocardiogram, often referred to as a cardiac echo, or simply an echo, is a sonogram of the heart. Usually, echocardiography uses standard two-dimensional ultrasound images of the heart. Echocardiography has become routinely used in the diagnosis, management and follow-up of patients with any suspected or known heart diseases. It can provide a wealth of helpful information, including the size and shape of the heart, pumping capacity, and the location and extent of any tissue damage.
