James Gandolfini was taken by ambulance to Policlinico Umberto I hospital where he was pronounced dead. The actor, best known for his role as Tony Soprano in HBO series The Sopranos, was just 51.

“The resuscitation maneuvers, including heart massage etc., continued for 40 minutes and then, seeing no electric activity from the heart, this was interrupted and we declared James dead,” said emergency room chief Claudio Modini.

“The patient was considered dead on arrival, and for that reason an autopsy has been requested to be carried out by a pathologist, as is normal procedure in our country.”

The autopsy is expected to be carried out today.
