stenosis
bioprosthetic valves r less durable and often deterioate with in 10-15 yrs while mechanical do not so she will have a valve failure and there will be eventual calcification or thrombus formation but she had the replacement right after her IE then therefore her chances of getting a PVE r increased thus she will have stenosis
I hope i m right read abt this some way long time back

it is hemolysis!
angiopathic anemia! with stenosed valves or prosthetics.
CBC and peripheral blood film will clear up the picture

embolization
nnl told the very right explanation....they have higher rate of stenosis as compared to the metallic ones...but the question is mentionin about IE... 
Thrombosis: this is a major potential problem with mechanical heart valves, requiring that the patient remain on anticoagulant therapy, though this will not entirely prevent thrombosis and subsequent embolization.
Infection: vegetations of infective endocarditis can develop on or around the prosthesis, and septic embolization can subsequently occur
Structural failure: this is a major problem with bioprostheses, because the leaflets tend to become stiff and calcify.
Dehiscence: seen mainly in the immediate postoperative period, dehiscence is separation of the prosthetic valve suture line from the heart, leading to paravalvular leakage
Disproportion: the prosthetic valve may not fit well in the heart, so that blood flow is not optimal.

here I must mention that dehiscence is equal to paravalvular leak
