On June 6, 2008, Hollywood High School dedicated a mural of Ritter painted by Eloy Torrez. In March 2010, the Thoracic Aortic Disease (TAD) Coalition, in partnership with Yasbeck and the John Ritter Foundation (JRF), announced the creation of the "Ritter Rules" which are life-saving reminders to recognize, treat, and prevent thoracic aortic dissection. The purpose of the JRF is to provide accurate information to the general public about the disease and its risk factors, provide support to individuals who have thoracic aortic disease or have lost a loved one to the disease, and improve the identification of individuals at risk for aortic dissections and the treatment of thoracic aortic disease through medical research. Yasbeck worked with the University of Texas Health Science Center at Houston (UTHealth) to establish the John Ritter Research Program in Aortic and Vascular Diseases with the goal of preventing premature deaths due to aortic dissection by identifying genetic mutations that predispose individuals to thoracic aortic aneurysms and dissections.
