How do you diagnosevalvular aortic stenosis ?

Echo: An echocardiogram (often called "echo") is a graphic outline of the heart's movement. High-frequency sound waves, called ultrasound, provide pictures of the heart's valves and chambers. This allows the technician, to evaluate the pumping action of the heart. Echo is often combined with doppler ultrasound and color doppler to evaluate blood flow across the heart valves and provides the diagnosis.
