Autopsy results confirm that star James Gandolfini's cause of death - he suffered a heart attack and died of natural causes - a family friend told the media.
The 51-year-old's sudden death instantly shocked and saddened fans Wednesday. As previously reported, Gandolfini had been visiting Italy with family.
"Today we received the results of the autopsy, which stated he died of a heart attack, of natural causes," Michael Kobold said in Rome on Friday.
"The autopsy further states that nothing else was found in his system."
News that James Gandolfini died stunned his family most of all, and they plan to put his body back on a plane to the U.S. as soon as they get clearance.
"We expect that to be Wednesday, maybe Thursday, but we will keep you informed," Kobold said, noting that funeral is expected in NYC late next week.
In a heartbreaking detail, the star's manager confirmed that Michael, James Gandolfini's 13-year-old son, found his father collapsed in his hotel room.
The three-time Emmy winner was then transported to the Policlinico Umberto I hospital; paramedics tried in vain to revive Gandolfini en route to the hospital.
Resuscitation maneuvers, including heart massage, continued for 40 minutes and then, seeing no electric activity from the heart, he was declared dead.
