A week after his passing, Bill Paxton's death certificate has been released.
In the certificate, obtained by TMZ, it was revealed that he died of a stroke after undergoing heart surgery.
Two weeks before his death, Paxton underwent a valve replacement and aortic aneurysm repair surgery, but suffered complications.
Paxton died at Cedars-Sinai Medical Center on February 28.
Earlier in February, Paxton opened up about his struggle with rheumatic fever, which he said had caused heart damage, during a podcast with Marc Maron. He contracted the illness when he was in the seventh grade. He told Maron, "I woke up one night — I had been to a hockey game, and I woke up one night and I had a lot of pain in my left wrist.”
