This form of echocardiography provides a wide overall view of the heart. It is ideal to assess the relative size of the four intracardiac chambers and the relationship of the thickness of the cardiac walls to the size of the chambers. Thus, for individuals with regional disorders such as intracardiac tumors, this mode of echocardiography is indispensible. Two-dimensional Echocardiography is also well suited to identify pericardial effusion. This mode of imaging may allow the identification of intracardiac shunts, prolapse of an atrio-ventricular valve leaflet, the obstruction of outflow of blood or the restriction to motion of a valve.
