Apparently there is an issue with St. Jude's silver coated Silzone heart
valves leaking around the seal. This problem can make the heart less
effective even causing heart failure. If you go to
https://www.lawyersandsettlements.com/case/silzone_mechanical_heart_valves
there is more information on this and other problems with the heart valves
as well as what can be done about it. There is also a free case evaluation
provided for those who may have been effected by this. I hope that this
might be of some help.
