The death of a Perth mother who had a heart procedure but later died from multi-organ failure after she suffered a punctured artery was "unnecessary" and "avoidable", the State Coroner has found.
Wendy May Aslett, 60, died on October 29, 2010 from complications associated with an angiogram she underwent eight days earlier at Subiaco's St John of God Hospital.
After Mrs Aslett was discharged from hospital the following day, she deteriorated, prompting her daughter to take her to her GP Dr Alida Lancee on October 25, but the doctor believed she had an infection and prescribed her antibiotics and painkillers.
State Coroner Alastair Hope today found Mrs Aslett's death was an accident but said her life could have been saved had she or Dr Lancee contacted her cardiologists or if she had returned to hospital.
"It is likely that the deceased did not appreciate the extent of deterioration of her condition or the sinister indications of the internal bleeding which she was suffering," Mr Hope said.
"It is clear that Dr Lancee did not fully appreciate the fact that she was at the time suffering ongoing bleeding and certainly was not alert to the act that her life was at risk."
Mr Hope recommended that all hospitals which offer angiograms provide patients with a discharge summary containing information about bleeding, pain levels and medication.
He also recommended that patients be advised to take the document to a doctor if they suffer any complications and that it be provided to the patient's GP as soon as possible.
