Aortic Stenosis
Aortic stenosis is narrowing of the aortic valve. Severe AS defined as valve area <1.0 cm². Classic triad: angina, syncope, dyspnea. TAVR has transformed treatment.

Core official overview
What this condition is
What are heart valve diseases?Heart valve disease happens when one or more of your heart valves don't work well.Your heart has four valves: the tricuspid, pulmonary, mitral, and aortic valves. The valves have flaps that open and close. The flaps make sure that blood flows in the right direction through your heart and to the rest of your body. When your heart beats, the flaps open to let blood through. Between heartb…
