The STS Intermacs Database became part of the STS National Database™ on January 1, 2018. It represents the next generation of Intermacs, a joint effort among the National Heart, Lung, and Blood Institute, the Food and Drug Administration, the Centers for Medicare & Medicaid Services, and others that was established in 2005 at the University of Alabama at Birmingham. Intermacs is a North American registry for the clinical outcomes of patients who receive an FDA-approved mechanical circulatory support device to treat advanced heart failure.

Established in 1989, the STS National Database is an internationally renowned clinical outcomes registry that helps cardiothoracic surgeons measure and improve patient care. Due to its exponential growth, both in terms of participation and stature, the Database has become the gold standard for clinical outcomes registries among health care administrators, government officials, and payers.

The Society of Thoracic Surgeons believes that physicians are in the best position to measure clinical performance accurately and objectively.

In addition to Intermacs, the STS National Database has three other components: the STS Adult Cardiac Surgery Database, the STS Congenital Heart Surgery Database, and the STS General Thoracic Surgery Database.

The addition of the Intermacs registry represents a new chapter in the history of the STS National Database in light of the registry’s collection of longitudinal data. The STS Intermacs Database includes longitudinal data for the life of a patient with an MCS device.
