Statistics and Outcomes
At Seattle Children’s Heart Center, our outcomes are among the best in the nation for simple to complex heart procedures and transplants for children. Our heart surgeons perform more pediatric cardiac procedures than any other providers in the Washington, Wyoming, Alaska, Montana and Idaho (WWAMI) region.
"Outcomes” refer to the results of treatment and evaluate how effective care is. We also provide statistics such as the number of patients seen (volumes).
We gather this data to:
- Measure the health of our patients
- Improve the quality of the care we provide
- Help you make informed decisions about your child’s care
Heart Center Volumes and Survival Rates
We treat the entire range of pediatric heart conditions – from the most common to the most complex and rare. We only treat babies, children, teens and young adults. This means we bring years of experience to your child’s unique situation.
Seattle Children’s Heart Center is the largest pediatric heart program in the WWAMI region and the third-largest program west of the Rocky Mountains.

Number of surgeries and 30-day survival rate
This table shows:
- The number (volume) of each type of complex heart surgery performed at Seattle Children’s Hospital
- The number of patients who survived more than 30 days after surgery (outcome). “30-day survival” is the measurement for success used by hospitals throughout the nation. Using this measurement allows you to compare us with other hospitals.

Pediatric heart transplant survival rates
This table compares survival rates at Seattle Children’s with the national average for pediatric patients. Pediatric patients are children who are not yet 18 years old when they are put on the transplant waitlist.
Seattle Children’s 1- and 3-year pediatric survival rates are among the best in the nation. Read more.
These data are for transplants performed in the following periods:
- 1-year survival: January 1, 2015 – June 30, 2017
- 3-year survival: July 1, 2012 – December 31, 2014
Transplant data updated January 2018.
Prenatal Diagnosis Volumes and Accuracy
This table shows the number of prenatal heart exams we did in each of the previous 3 years. It also shows how accurate we are in making the diagnosis during pregnancy. Some things cannot be detected before birth due to the differences between blood circulation during pregnancy and after birth.
Where does this information come from?
These statistics and outcomes reflect national metrics reported to the National Quality Forum, the Society of Thoracic Surgeons (STS) and the Scientific Registry of Transplant Recipients.
Who do I contact if I have questions?
