The equation above explains the pathologic process that develops over many years in patients with aortic stenosis. As obstruction to forward flow slowly increases over time with worsening aortic ...

The diagnosis of aortic stenosis is made mostly on physical examination and by echocardiography. The ECG in patients with aortic stenosis frequently shows left ventricular hypertrophy with strain ...
