ANSWER: Hello Amrita,

Biologic valves probably best for a 56 year old.  They last at least 10 years, probably 15 or 20, and don't require permanent anticoagulation to prevent clots.

QUESTION: thank you doctor,tissue valves r definitely better option as far as risks of using anticoagulants r concerned,bt i had sm other doubts abt it like-1)wat about d side effects of tissues valves,do de cause tissues reaction or rejection as de r foreign proteins forcing d recipient for immunocompression.
2)in about hw much tym tissue valves start getting hardened or fibrotic.......wat if it starts very early n also wat if de get infected n get dysfunctional(dese problems won't be dere in metallic ones)
3)stented tissue valve is better or stentless one
4)if we opt for metallic one n hv to use anticoagulants den r dere chances of ny internal haemorrhage also(may be like in cerebral arteries due to HTN or in anal canal due to constipation etc.)

plz reply.....thank you

Answer
Hello Amrika,

1) No tissue reaction or rejection.  The valves are treated so they are biologically inert.
2) Tissue valves last for 7 to 10 years or longer before hardening.
3) I don't think there's much difference.
4( Yes, some chance of internal hemorrhage, usually brain or intestine.  Rare if one is careful with the anticoagulant.
