Surviving High-risk Cardiovascular Surgery at the Bluhm Cardiovascular Institute - Better than National Odds

Northwestern Memorial Hospital August 14, 2011

Medicare population survival rates show sharp increase according to an article in the New England Journal of Medicine.

CHICAGO, IL – Results from a recent article in the New England Journal of Medicine* show that the odds of a Medicare patient surviving one of eight high-risk surgeries has increased sharply. This is good news for the estimated 45 million Medicare recipients, but even better for those Medicare recipients that undergo these surgeries at Northwestern’s Bluhm Cardiovascular Institute as our survival rates for these cardiovascular surgeries are better than the national odds.

Of the eight high-risk surgeries that were studied in the article, four are cardiovascular surgeries. The information below compares the national operative mortality rates for these surgeries to operative mortality rates at the Bluhm Cardiovascular Institute. Operative mortality is defined as death within 30 days of the surgery or death before discharge from the hospital.

AAA repair operative mortality graphAbdominal Aortic Aneurysm (AAA) Repair
The most recent Medicare data shows that operative mortality for abdominal aortic aneurysm repair has dropped to 2.8 percent in the United States. At the Bluhm Cardiovascular Institute operative mortality has been 1.9 percent over the last 5 years (2004-2008).

Aortic valve replacement mortality graphAortic Valve Replacement
The most recent Medicare data shows that operative mortality for aortic valve replacement repair has dropped to 6.6 percent in the United States. At the Bluhm Cardiovascular Institute operative mortality has been 0.7 percent over the last 5 years (2004 - 2008).

CABG mortality graphCarotid Endarterectomy (CEA)
The most recent Medicare data shows that operative mortality for carotid endarterectomy repair has dropped to 1.2 percent in the United States. At the Bluhm Cardiovascular Institute operative mortality has been 0.8 percent over the last 5 years (2004 - 2008).

Cartoid endartectomy mortality graphCoronary Artery Bypass Grafting (CABG)
The most recent Medicare data shows that operative mortality for coronary artery bypass grafting repair has dropped to 3.4 percent in the United States. At the Bluhm Cardiovascular Institute operative mortality has been 0.8 percent over the last 5 years (2004 - 2008).
