Former Iron Maiden singer Paul Di'Anno's cause of death revealed

According to the statement, Di'Anno's sisters Cheryl and Michelle confirmed their brother "had a tear in the sac around the heart and blood has filled inside it from the main aorta artery and that has caused the heart to stop."

"Paul's death was instantaneous and hopefully painless. May he rest in peace," the statement added.

Di'Anno died last month at the age of 66.

Representatives for Di'Anno confirmed the news to Fox News Digital at the time, saying the singer died at his home in Salisbury, England. 

"On behalf of his family, Conquest Music are sad to confirm the death of Paul Andrews, professionally known as Paul Di'Anno. Paul passed away at his home in Salisbury at the age of 66," representatives and family for Di'Anno said in a statement to Fox News Digital. "Born in Chingford, East London, on 17th May 1958, Paul first came to prominence as lead singer of English Heavy Metal band Iron Maiden, between 1978 and 1981."

The singer began experiencing health issues in the 2010s, including knee surgery in 2014 that often had him performing live shows in a wheelchair. He also had a cancer scare.

"It was an abscess that was all infected and the size of a rugby ball. It turns out I've been living with this thing in me for the last few years," Di'Anno said.

He added, "I suppose I'm pretty damn lucky, but the last six months have been hard."

His family's statement upon his death said, "Despite being troubled by severe health issues in recent years that restricted him to performing in a wheelchair, Paul continued to entertain his fans around the world, racking up well over 100 shows since 2023."

The Facebook post sharing Di'Anno's cause of death also noted there was a tribute show to the late singer this past weekend at Underworld Camden, a rock venue in London.

"With a magnificent musical set, his musical colleagues said a worthy farewell to their friend," the post read.
