The California Society of Thoracic Surgeons (CA STS) is a non-profit organization supported by surgeons, heart hospitals and heart team members. The CASTS reporting project, the California Cardiac Surgery and Intervention Project (CCSIP), was developed with unrestricted grants from non-profit foundations and medical product companies. The CCSIP reports an important source of information not only to heart team members but to all stakeholders, including patients and companies that manufacture heart valves and other medical devices. The CASTS and the CCSIP depend on the support of our constituents, healthcare organizations as well as industry sponsors.
