A mother was killed at her hospital appointment by a doctor who botched a routine procedure, a court has heard.
Dr Isyaka Mamman, 85, was responsible for a series of critical incidents before the fatal appointment, Manchester Crown Court heard.
Mamman, who admitted gross negligence manslaughter, had already been sacked by medical watchdogs for lying about his age but was re-employed by the Royal Oldham Hospital.
He is due to be sentenced on Tuesday.
Mother-of-three Shahida Parveen, 48, had gone to hospital with her husband for investigations into possible myeloproliferative disorder on 3 September 2018 and a bone marrow biopsy had been advised, Andrew Thomas QC, prosecuting, told the hearing.
Normally, bone marrow samples are taken from the hip bone but Mamman, of Cumberland Drive, Royton, Oldham, failed to obtain a sample at the first attempt, he said.
Instead, he attempted a rare and "highly dangerous" procedure of getting a sample from Ms Parveen's sternum - despite objections from the patient and her husband, the court heard.
Mamman, using the wrong biopsy needle, missed the bone and pierced her pericardium, the sac containing the heart, causing massive internal bleeding.
Ms Parveen lost consciousness as soon as the needle was inserted. She died later that day.
