30-Day Surgical Mortality: Coronary Artery Bypass Graft and Aortic Valve Replacement

A coronary artery bypass graft addresses the most common form of heart disease, blockages limiting flow of blood through the coronary arteries.


If aortic valve replacement is also needed, UW Health surgeons can combine both these procedures during one surgical procedure.


The graph below shows UW Hospital's outcomes for adult patients who underwent combined bypass surgery and aortic valve replacement.


UW Hospital's mortality rates are consistently lower than other hospitals. 

  • Vertical axis: 30-day mortality rate percentages
  • Horizontal axis: Year 
UW Hospital 0.0 4.8 4.7 0.0 0.0 0.0
All STS 5.3 4.9 5.3 4.8 4.5 4.2
