The heart valve can calcify and cause narrowing of the valve which is called stenosis. Stenosis happens most often in the aortic valve, but can occur in any of the heart’s four valves. When a healthy ...

A paradoxically split S2 heart sound can be caused by aortic stenosis ... a closed tricuspid valve), which occurs in the setting of AV dissociation (complete heart block or ventricular tachycardia).

Description Aortic stenosis occurs when the aortic valve, which separates the main pumping chamber of the heart from the circulation, becomes narrowed. This may reduce the flow of blood out of the ...
