Aortic Valve Replacement

My have gone for 2D Echo with color doppler study.
And Observations :
1.. Aortic valve:- Thick, Trileaflet valve, Severe AR, No AS, Annulus-25mm.
2.. Mitral valve:- Trivial MR.
3.. Tricuspid & Pulmonary valves are normal.
4.. Noramal LV Size with fair LV systolic function. (LVEF=50%). No RWMA.
5.. LA,RA & RV are normal in size.
6.. NoPAH
7.. IAS & IVS are intact
8.. No clot/ vegetarian
9.. No pericardial effusion.
10.. Doppler study revealed Trivial MR, Severe AR, No TR.

I want to know the is AVR required at this stage or not?
If yes then which valve to go for Biotic or Artificial.
If you see any other fincding from the observation please let me know urgentlly.

Q: "Noramal LV Size with fair LV systolic function."

>>>>Normal EF is 50 to 70%.  This the amount of blood pumped with each heartbeat from the left ventricle to the system.  AVR, the aorta valve is non-compliant and blood pumped from the LV is less as much of the blood is back flowed into the LV.  If and when the low cardiac output will cause the left ventricle to enlarge and that could lead to heart failure(heart is not meeting the system demand for oxygenated blood.

The risk of not correcting the valve problem can/will enlarge the left ventricle and that would further reduce the EF.  A surgeon at Mayo Clinic who has done thousands of heart valve operations is on record that the biggest problem he sees is the partient waited too long.  If the EF is reduced and an enlarged LV, replacement of the valve may not restore good functionality.  You may want to get an opinion of a surgeon that you are comfortable.

The general thinking about the appropriate valve replacement is an artificial for the younger individual, and biotic for the older population as the biotic has limited functionality.  

Hope this provides a perspective, and if you have any further questions or comments you are invited to respond.  Take care,
