Rapper Kanye West's mother Donda, 58, died of heart disease and "multiple post-operative factors", according to a coroner's report.
Donda died on November 10 last year, a day after she underwent cosmetic breast reduction, tummy tuck and liposuction procedures.
The Los Angeles coroner said an autopsy failed to pinpoint the exact cause of death, but confirms West did not die as a result of "surgical or anaesthetic misadventure".
The report reads: "The final manner of death could not be determined. Multiple post-operative factors could have played a role in the death. The exact contribution of each factor could not be determined. There was no evidence of a surgical or anaesthetic misadventure."
l Morgan Freeman escaped death in a horse-riding accident, just weeks after Christopher Reeve was left paralysed after falling from a horse.
The Oscar winner, who co-starred with Reeve in 1987's Street Smart, owns seven horses at his ranch in Mississippi.
He says, "I grew up watching the movies. I always wanted to be a cowboy." - Wenn
