[|Human|] hi there my father has an aortic stenosis condition...we knew about it.today he said he felt bit tight in the chest which happens from time to time,but only tonight i notice that his ankle especially the left one swells like i have never seen before.is this something serious, as in i need to find a doctor or bring him to the hospital or is this just come with the tightness and when the tightness goes away tomorrow the ankle will be back to normal?
[|AI|]  Dear sir/ma'am, I must insist that you take your father to the ER for a 2d echo of the heart especially to see the ejection fraction. Ankle swelling is a sign of heart failure in patients of aortic stenosis and I cannot stress enough the need for him to go the hospital immediately. On top of that tightness in the chest is a classical angina pain which means the heart is overworked.The ankle is swollen because the heart is not able to pump the blood as it is in failure and so the blood accumulates in the extremities due to gravity. This leads to an increase in interstitial fluid and causes ankle swelling or edema in the medical term. I hope your father feels better
