Bill Paxton died from a stroke on Feb. 25, 11 days after heart valve replacement surgery, states the actor’s death certificate.

Paxton was also undergoing surgery to repair damage to his aorta, the main artery that carries blood from the heart to the body. He was 61.

The actor, best known for his role in the tornado-chasing “Twister”, appearing in many fan favourites, including “Aliens”, “Titanic” and TV series “Big Love”.
