Alan Thicke’s Official Cause of Death Revealed, Paula Patton Pays Tribute to Former Father-in-Law

Paula Patton shared a heartfelt tribute to her former father-in-law Alan Thicke on Tuesday, Dec. 20 after he was laid to rest by his family and friends.

Patton, who separated from Alan’s son Robin Thicke in 2014, remembered the late Growing Pains actor in a post on Instagram. “I knew Alan since I was 15 years old and he had a tremendous effect on my life,” Patton wrote in the caption of the photo below. “I loved and respected him so much! So many great memories and laughs together. We will miss him so much! His grandson is quite sure he is still here with us in spirit.”

Patton gave birth to Alan’s grandson Julian Fuego in April of 2010.

The official cause of Alan’s death was revealed on Wednesday (Dec. 21). According to Entertainment Tonight, the actor’s death certificate states that he died of a “ruptured aorta” and a “standard type A aortic dissection.” Though he died only three minutes after his aorta ruptured, the document lists that it was three hours between the onset of the aortic dissection and the time of his death.

A type A dissection is a tear that begins in the ascending aorta and progresses throughout the vessel. Symptoms include sudden severe chest pain or back pain, vomiting, sweating, and lightheadedness. A median sternotomy was performed on Thicke on Dec, 13, though he did not survive. His time of death is listed as 2:14 p.m. on that day.

Darin Mathewson from Pickwick Gardens ice skating ring in Burbank, California — the rink where Thicke collapsed — told ET that he was coherent when the emergency medical staff arrived. “He said he had pain in his chest, but his color was not good,” Mathewson said. “He was a little gray. When the ambulance got here they checked his vitals … and they put him on the gurney, sat him up.”

“When he went by us, he gave us the thumbs up, like, ‘I’m doing good guys, I’m good,'” he added.

Thicke was 69 years old when he passed away.
