Tissue valves are created from animal donors’ valves or other animal tissue that's strong and flexible. Tissue valves can last 10-20 years, and usually don't require the long-term use of medication. For a young person with a tissue valve replacement, the need for additional surgery or another valve replacement later in life is highly likely.

Also called TAVR (transcatheter aortic valve replacement), the FDA-approved TAVI procedure is only appropriate for select patients with severe symptomatic aortic stenosis (narrowing of the aortic valve opening) who are not candidates for traditional open chest surgery or who are high-risk operable candidates.

Aortic dissection may be a late sequela of . 18% of individuals who present with an acute aorticdissection have a history of open heart surgery. Individuals whohave undergone aortic valve replacement for are at particularly high risk. This is becauseaortic insufficiency causes increased blood flow in the ascendingaorta. This can cause dilatation and weakening of the walls of theascending aorta.

There are multiple etiologies for AI in the setting of ascendingaortic dissection. The dissection may dilate the annulus of the , so thatthe leaflets of the valve cannot coapt. Another mechanism is thatthe dissection may extend into the aortic root and detach theaortic valve leaflets. The third mechanism is that if there was anextensive intimal tear, the intimal flap may prolapse into the LVoutflow tract, causing intimal into the aortic valvepreventing proper valve closure.
