Kline: Ritter Foundation's Work Could Have Prevented Death
4 Nov
Summary
- John Ritter died in 2003 from a thoracic aortic dissection.
- The John Ritter Foundation's work saved his brother's life.
- His father also likely died from an aortic dissection.

Richard Kline expressed that the knowledge now available through the John Ritter Foundation could have saved his late co-star John Ritter's life. Ritter tragically passed away on September 11, 2003, at age 54 due to a thoracic aortic dissection, a rare and critical condition.
The foundation, established in Ritter's honor by his wife Amy Yasbeck, has been instrumental in funding research and raising awareness about aortic aneurysms and dissections. Kline highlighted its impact, revealing that the foundation's work directly led to the life-saving diagnosis and surgery for John's brother, Tom Ritter.
Yasbeck further elaborated that Tom's condition, an aneurysm in the ascending aorta, was similar to John's. She also noted that their father, Tex Ritter, likely died from an aortic dissection, a condition then misdiagnosed as a heart attack. This underscores a potential genetic predisposition within the family.
Friends and colleagues continue to honor Ritter's memory. Kaley Cuoco, who starred with him on "8 Simple Rules," recently participated in the foundation's Aortic Dissection Awareness Week, emphasizing Ritter's lasting influence.
