Adult Cardiac Surgery Database

The STS Adult Cardiac Surgery Database (ACSD) is the world's premier clinical outcomes registry for adult cardiac surgery. Launched in 1989, the Database contains more than 6.2 million cardiac surgery procedure records and currently has more than 3,100 participating physicians, including surgeons and anesthesiologists.



Data Collection

STS has compiled a training manual, data collection forms, and additional resources to aid in data collection for the Adult Cardiac Surgery Database.


Executive Summaries

Executive summaries provide a high-level overview of each Database for the reporting period. Executive summaries contain volume data by selected procedures and unadjusted operative mortality for selected procedures.

Sample Data Analysis Reports

These sample Data Analysis Reports are examples of the quarterly Data Analysis Reports received by ACSD Participants. Each Data Analysis Report provides Participant-level data compared to the STS Benchmark and to Like Groups for each reporting period.
