Echocardiography is a fundamental method for diagnosing structural heart diseases such as cardiac enlargement, myocardial diseases, valvular heart diseases, hypertensive heart diseases, heart failures, pericardial diseases, intracardiac masses (including clots and tumors), and congenital heart anomalies. Furthermore, it is also used in the diagnosis of diseases of the aorta, the body's largest artery. Echocardiography is also utilized for the routine follow-up and monitoring of patients who have undergone cardiac surgery.
