Aortic stenosis must be differentiated from other cardiac or pulmonary causes of dyspnea, weakness, and dizziness.  Furthermore, when left ventricular outflow tract obstruction is present, it is critical to identify whether the obstruction is subvalvular, valvular or supravalvular and whether there is  hypertrophic cardiomyopathy (HOCM) or not.
