Aortic Stenosis

Aortic stenosis is a fixed obstruction of left ventricular outflow caused by narrowing of the aortic valve.

In this episode, Chris and Mars review:

• Calcific and bicuspid aortic stenosis
• The classic murmur and carotid radiation
• Pulsus parvus et tardus
• Why severe disease causes dyspnea, angina, and exertional syncope
• Echo criteria for severe aortic stenosis
• Aortic stenosis versus hypertrophic cardiomyopathy
• When aortic valve replacement is indicated
• Surgical versus transcatheter valve replacement
• Heyde syndrome

Episode pearl: Severe aortic stenosis plus symptoms means the patient needs valve replacement—not simply more medical therapy.
