Question Aortic Valve Replacement

Hello,

Is there anyone out there with knowledge of Aortic Valve replacement and when an aortic valves deterioration affects your class 1 medical. Is replacement mainly based on pressure gradient and if so what is the mm hg gradient that triggers grouding or alternatively replacement surgery? I have heard that in the general population replacement is considered around 60mm gradient, but for aircrew about 40mm gradient. does this sound about right? As I understand it pig valves can regain your class 1, but mechanical valves mean permanent grounding. Any advice welcome.

Thankyou and Regards,
