What was wrong with Lucille's balls Heart?

Answer 1

"On April 18, 1989, Ball was at her home in Beverly Hills when she complained of chest pains. An ambulance was called and she was rushed to the emergency room. She was diagnosed as having a dissecting aortic aneurysm and underwent heart surgery for nearly eight hours, receiving an aorta from a 27 year old male donor. The surgery was successful, and Ball began recovering, even walking around her room with little assistance. On April 26, shortly after dawn, Ball awoke with severe back pains. Her aorta had ruptured in a second location and Ball quickly lost consciousness. All attempts to revive her proved unsuccessful, and she died at approximately 05:47 PST. She was 77 years old."
