Tanya Barnett's daughter Jessica died in 2007 from a heart defect. It was a treatable condition that had been misdiagnosed by doctors.
Now, Ms. Barnett was hoping the doctors involved in her daughter's case would take part in a research project that could prevent the same thing from happening to other families. But the MDs have refused to participate. Carol spoke with Ms. Barnett, who is at her home in Wolfville, Nova Scotia.
