Aortic Stenosis-2nd Valve Replacement

Posted By Charles on December 13, 1998 at 22:09:13:







I am a 48 year old male.  I had my aortic valve replaced in 1991.  I elected to get the porcine bioprosthesis.  I understood the likelihood that I would have to undergo valve replacement again.  However, I was hoping that there would be a better procedure and, perhaps, a mechanical replacement that would not require the blood thinning drugs.  At that time, there seemed to be talk of "defective" mechanical valves and I felt that I had better chances with the bioprothesis.  On my last checkup, my cardiologist said that my most recent echo doppler test revealed a worstening condition that would probably require valve replacement this year if the pattern  continues.  This was not expected since I have never felt better.  I have no symtoms (symptoms) at all.  My questions are:
1. Would I be a candidate for the Ross Procedure?
2. Would minimally invasive surgery be a consideration?
3. Are there any practical options to a mechanical valve?
4. Are the latest machancial valves less prone to clotting?
I am not a doctor but I really need to understand.  I appreciate your help.
