The University of Washington Pediatric Cardiology Training Program will produce pediatric cardiologists with the cognitive and procedural expertise to provide excellent care to children with cardiovascular disease and the academic skills to make meaningful scholarly contributions.

Training at the University of Washington School of Medicine:
Each year, approximately 1,200 residents and fellows conduct their ACGME training at one of UW’s primary training sites. For more information, including appointment information and stipends visit the Prospective Residents and Fellows page.




First Year

The first year is primarily clinical. The fellow is exposed to all the areas of clinical cardiology through month-long rotations. First-year fellows also participate in the continuity clinic.

Second and Third Years

In their second and third years, fellows focus on developing research skills and take on increasing clinical responsibilities. The program is designed to allow for approximately two years of clinical training and one year of research time.


Major categories of clinical exposure include inpatient cardiology, echocardiography/noninvasive imaging, cardiac catheterization, electrophysiology, cardiac intensive care, cardiothoracic surgery, heart failure/transplant and adult congenital heart disease.


Research opportunities include clinical, basic science and transitional research. Faculty research interests include cardiac metabolism, cardiac regeneration, Kawasaki disease, outcomes research in adult patients with congenital heart disease, interventional/hybrid treatment for congenital heart disease, and clinical applications of noninvasive imaging.
