What Is Aortic Valve Stenosis
A valve is a structure that regulates the direction of flow. The heart is a special kind of pump. It moves blood by squeezing and relaxing. There are 4 chambers and each chamber has a valve. This keeps blood from moving backwards when the heart squeezes. When a chamber squeezes it lets the blood move forward but when the chamber is relaxed it prevents the blood from ...Read more
Multiple: Perhaps the most common offending etiology in aortic stenosis in the us is atherosclerosis. Just as this can affect the arteries in the body, it can affect the tissues covering the aortic valve and then the plaque deposition and calcific degeneration of the valve leads to its problems. Rheumatic heart disease, not common in the us, is another common cause in third world countries. ...Read moreSee 1 more doctor answer

The more common is degenerative or senile which is seen in the elderly. The cause is likely multifactorial and may share some similarity to atherosclerosis. ...Read more
VALVE AREA?: Depends on the valve area, transvalvular gradient, contractility, ejection fraction, left ventricular end diastolic and systolic dimensions, and overall physical conditionig. Need echo findings, blood pressure and heart rate and transvalvular gradients. ...Read moreSee 2 more doctor answers

It then closes firmly to prevent blood from flowing backwards, while it passively continues to flow forward to body's vital organs. When next heartbeat ...Read more
