Echocardiography plays a fundamental role in the diagnosis of all structural heart diseases, including cardiac enlargement, myocardial diseases, heart valve diseases, hypertensive heart diseases, heart failure, pericardial diseases, intracardiac masses, clots, heart tumors, and congenital heart anomalies. Furthermore, it is used in the diagnosis of diseases related to the aorta, the body's largest artery. It is also an indispensable tool for the routine follow-up and check-ups of patients who have undergone cardiac surgery.
