The results of James Gandolfini's autopsy have confirmed the star died of natural causes.

The Sopranos star passed away on Wednesday (19Jun13) during a family vacation in Rome, Italy and local officials have now confirmed his cause of death was a heart attack.

The results of the actor's autopsy, which was carried out on Friday (21Jun13), were made public by a family friend, Michael Kobold, who held a press conference and read a statement on behalf of Gandolfini's relatives.

He said, "James came here on a vacation with his family... he had a wonderful day. He visited The Vatican and had dinner at the hotel with his son awaiting the arrival of his sister. Today we received the results of the autopsy, which stated he died of a heart attack, of natural causes. The autopsy further states that nothing else was found in his system.

"We are all devastated by this loss. James was a devoted husband, a loving father of two children, a brother and cousin you could always count on. We thank you for the privacy you have afforded us during this difficult time."
