The official cause of death of former Growing Pains star Alan Thicke released on Wednesday, Dec. 21, confirmed that the actor died from a ruptured aorta.

The 69-year-old complained of chest pains while playing ice hockey with his son, Carter, on Dec. 13. He was rushed to a nearby hospital where he later died.
