Heart Surgery Safety and Surgical Outcomes

The CHOC Heart Institute is committed to safe surgical outcomes and the highest quality of care possible for our patients.

For more than a decade, CHOC has been a member of the Society of Thoracic Surgeons (STS) National Database, an international benchmarking organization that sets the highest standards for hospitals performing heart surgery. CHOC was among the first 15 institutions to join the registry and report surgical outcome data. Today, there are more than 130 premiere hospitals in the STS database.


Heart surgery survival rates

CHOC survival rates compared with national STS survival rates for all heart surgery procedures from July 2014 through June 2018.

The Society of Thoracic Surgeons

The Society of Thoracic Surgeons (STS) is a non-profit organization dedicated to promoting the best possible outcomes for thoracic surgeries (surgeries of the heart, lung and esophagus).

The STS National Database is the leading clinical data registry for cardiothoracic surgery. Participating medical centers can compare their outcomes against STS national benchmarks.

STS outcome rates disclose not just each center’s success rate, but what experts thought the success rate should have been taking into consideration how sick and fragile the patients were prior to surgery. Additionally, the STS performs its own objective audits of hospital data to ensure accuracy without bias.
