Two-dimensional transthoracic echocardiography can confirm the clinical diagnosis of aortic stenosis and provide specific data on LV function. The etiology of aortic stenosis (bicuspid, rheumatic, or degenerative calcific) may be assessed from the 2D echocardiographic, parasternal, short-axis view. The structure and function of the other heart valves can also be assessed.
