[|Human|] Respected Sir, I am from from Kolkata. My father(56 years) is suffering from Severe Aortic Stenosis. All the doctors that we have visited recommended an Aortic Valve  Replace (AVR).We are really worried about him.Sir will be grateful to you for your suggestions..
[|AI|]  Hi Mr/MMR Xxx ! I have gone through your question and I understand your concern. Yes the doctors that recommended that are right, Your father need an Aortic value replacement. In the case that the Aortic stenosis is severe means that the heart is working hard to pump the blood into the vessels and this condition makes the heart muscles weak. The heart cant effort the obstruction caused by the aortic stenosis and in the end this will lead to heart failure and less and less blood in the vessels (all the body will suffer from leak of oxygen.) Its necessary to remove the obstruction in this case the aortic value to prevent further heart dysfunction cause if the left muscle ventricle gets to a point that they are weak, is nothing that we can do to repair. Fortunately the valve replacement are operations that the doctor are used to and its part of their everyday practice. Wish your father good health. If you have any other questions please feel free to ask me. Thank you for using Chat Doctor.
