Aortic Valve Replacement

Aortic Valve Replacement

Aortic Valve Replacement (AVR) is an operation for treatment of narrowing (stenosis) or leakage (regurgitation) of the aortic valve. Sometimes, the valve can be repaired, but most often, it is replaced with a valve made of animal tissue or a mechanical valve. An "isolated" Aortic Valve Replacement occurs when AVR is the only major cardiac surgery performed.

What are we measuring?

The number of Aortic Valve Replacement (AVR) surgeries performed annually.

Why is this important

Studies have found that surgical teams with experience - that is, routinely performing a sufficient number of cases - get better results. The Leapfrog Group, a nationally recognized patient safety organization recommends that hospitals such as BIDMC perform at least 120 or more AVR procedures annually

Mortality Rate

What are we measuring?

Inpatient Mortality Rate is the percentage of patients who do not survive Isolated AVR surgery and die at any point during their hospital stay. 30-day Mortality rate is the percentage of patients who do not survive Isolated AVR surgery and die within 30 days immediately following surgery.

Why is this important?

Mortality rate provides general information about the quality of care delivery, and can be an important quality indicator. However, some hospitals care for patients with a greater severity of illness and therefore may have a higher mortality rate.

What is BIDMC's performance?

At BIDMC, the Inpatient Mortality Rate for Isolated AVR surgery in CY 2010 is 0%. A national database reports a national average Inpatient Mortality of 2.6% for Isolated AVR surgery.

The 30-Day Mortality Rate for Isolated AVR surgery at BIDMC in CY 2010 is 0%. A national database reports a national average 30-day Mortality Rate for Isolated AVR surgery of 3.0%.

Therefore, BIDMC's Inpatient and 30 Day Mortality performance appears better than the national average for Isolated AVR surgeries.

Length of Hospital Stay

What are we measuring?

The average number of days a patient undergoing Aortic Valve Replacement (AVR) surgery stays in the hospital.

Why is this important?

The number of days that AVR surgery patients must stay in the hospital is a way of looking at both the efficiency of care as well as its effectiveness. A shorter average length of stay may indicate that patients are recovering more quickly and experiencing fewer complications.
