The LA County Coroner has concluded that Donda West - mother and manager to son Kanye - died of a heart attack after her cosmetic surgery.

As previously reported, West, 58, died on Saturday, November 10, 2007 after complications from cosmetic surgery.

According to TMZ, the coroner's report says West died of "coronary artery disease and multiple post-operative factors due to or as a consequence of liposuction and mammoplasty."

The report could not state with certainty what exactly killed her but there was no evidence that anesthesia or even the surgery is to blame.

Donda was very close to her son. Kanye often spoke of her in his music, and dedicated the track "Hey Mama" to her off his second release, Late Registration. Chicago rapper, Rhymefest, said that Donda was like a mother and mentor to the entire circle.

"She was a mother to everybody ... We all came in the crib and she fed us when we had nothin', when there was no record deals. She brought us in," he said. "She was a mother for a community, and a mother for one of Chicago's greatest heroes."
