Last week, Alan Thicke unexpectedly passed away at age 69, and now his death certificate has been released.
The death certificate revealed that he died from a “ruptured aorta” and a "standard type A aortic dissection.”
In an attempt to save Thicke’s life, doctors performed a median sternotomy, in which a vertical incision is made along the sternum, the area around the heart and lungs.
Despite the surgery, Alan died three hours after he suffered the heart attack. The time listed for his death was 2:14pm on December 13.
TMZ was first to report the news.
