Echocardiography employs high-frequency sound waves emitted by a transducer. These waves bounce off the heart's structures and return as echoes, which are then translated into visual images. This allows for real-time assessment of the heart's chambers, valves, and blood flow patterns. Different types of echocardiography include Transthoracic Echocardiography (TTE), Transesophageal Echocardiography (TEE), and Stress Echocardiography.
