Harney knew of scan misdiagnosis last August
In a written answer to a parliamentary question, she confirmed she was contacted by solicitors acting on behalf of Melissa Redmond on August 7 last year.
The letter – which was also copied to HSE chief executive Prof Brendan Drumm and the State Claims Agency – outlined how Ms Redmond, from Donabate in north Dublin, almost lost her child due to an incorrect scan which incorrectly said the foetus had died.
