Which of the following are the main types of echocardiography?

The primary types of echocardiography include Transthoracic, Transesophageal, and Stress echocardiography, all of which play crucial roles in assessing cardiac function and structure.

Transthoracic echocardiography (TTE) is the most common type, performed non-invasively using a transducer placed on the chest to obtain images of the heart. It provides real-time visualization of cardiac anatomy and function, making it a fundamental tool for diagnosing various cardiac conditions.

Transesophageal echocardiography (TEE) involves the insertion of a specialized probe into the esophagus, which allows for closer and clearer images of the heart. This method is particularly useful when imaging through the chest wall is inadequate, enabling better assessment of certain conditions, such as valvular heart disease and cardiac masses.

Stress echocardiography combines echocardiography with a form of physical or pharmacologic stress. This technique is important for evaluating how well the heart functions under stress, helping diagnose conditions like coronary artery disease.

The other choices include terms that are either inaccurate or not primarily classified as echocardiographic techniques. For instance, Retrograde and Transpulmonary do not refer to standard echocardiography methods, and Cardiac CT
