Prognosis - Aortic Stenosis

-Without surgery, a person with aortic stenosis who has angina or signs of heart failure may do poorly.
-After surgery there is a risk for irregular heart rhythms, which can cause sudden death, and blood clots, which can cause a stroke.
-There is also a risk that the new valve will stop working and need to be replaced

Aortic valves replacement surgery :
-The overall mortality risk : 5%
-Advanced age should not be a reason for not recommending aortic valve replacement for aortic stenosis.
-Otherwise healthy patients in their 80s with strong heart muscles often benefit dramatically from aortic valve replacement for critical aortic stenosis.

Balloon Valuloplasty:-Those who respond to valvuloplasty with improvement in ventricular function can be expected to benefit even more from aortic valve replacement.
-Aortic valvuloplasty in these high risk elderly patients has a similar mortality (5%) and serious complication rate (5%) as aortic valve replacement in surgical candidates.
-In critically ill patients, the mortality rate associated with the procedure is 3-7%.
-Another 6% develop serious complications including perforation, myocardial infarction, and severe aortic regurgitation.
