âMadnessâ doctors didnât see mum before fatal scan A healthy mum should have seen a doctor before an invasive heart scan that claimed her life, an inquest has heard. Health by WES HOSKING Premium Content Subscriber only A doctor whose name was used to sign off on a heart scan which killed a healthy mum thought she'd been assessed beforehand, declaring not doing so would be "madness". Dr Doumit Saad told a coronial inquest he'd never let a patient undergo such an invasive procedure without first making sure it was suitable. Dr Saad said he'd only ever been commissioned to review CT coronary angiograms a company had suggested for senior executives including Peta Hickey, 43, who suffered a fatal anaphylactic response to contrast dye at a Moonee Ponds clinic.
