The Society of Thoracic Surgeons Adult Cardiac Surgery Database: 2024 Update on National Trends and Outcomes

The Society of Thoracic Surgeons (STS) Adult Cardiac Surgery Database (ACSD) is the most robust and advanced clinical database in cardiac surgery. With more than 8.3 million procedures and more than 1000 participating institutions encompassing more than 97% of cardiac surgery in the United States, the ACSD is the specialty's vital instrument for quality improvement, patient safety, and outcome reporting in cardiac surgery. The database continues to advance initiatives to achieve these goals, which recently have included adding new risk models for multivalve procedures, isolated tricuspid valve surgery, aortic valve replacement after transcatheter aortic valve replacement, and mitral valve surgery for degenerative mitral regurgitation. In addition, the ACSD can now provide longitudinal survival data through linkage to the National Death Index. This report reviews current trends in the ACSD through the end of 2023, impactful research during the past year, and database innovations being implemented.
