Genomic DNA Prep from Heparinized blood?

[Robert Wildin]

 I received a sample of blood accidentally anticoagulated with heparin. 
I am told that Genomic DNA isolated from heparinized blood is much harder 
to use in PCR reactions.
Does anyone have experience with this?  Is there a way to get around the 
purported problem?  Is there a quick and dirty way to get rid of teh
heparin?
Any thoughts appreciated.
