Loading Calculator


Enter your medical information to the best of your knowledge. If there is information that you do not know, it is ok to leave those fields blank. If left blank, the risk calculator will assume that you are like the majority of others who have undergone these two procedures. Consider asking your health care team to provide you with any unknown information because the risk calculator is more accurate if complete information is entered (for example, your recent laboratory values, echocardiography and cardiac catheterization reports).

Exclusion criteria: If you have any of the following characteristics, this calculator will not be applicable to you:

  • Age < 65 years old or > 90 years old
  • If your chest has been deemed inoperable due to factors such as scar tissues or prior radiation (i.e. “hostile chest”)
  • If you have to undergo another open heart surgery at the same time (such as another valve or a procedure to treat atrial fibrillation. A CABG at the same time of your procedure is OK.)
  • If you have aortic insufficiency (regurgitation) without aortic stenosis
  • If you have or had endocarditis, an infection of your aortic valve
  • Moderate or severe mitral stenosis
  • If your procedure must go immediately, usually within less than 12 hours, to avoid death (emergent or emergent salvage)
  • STS PROM score </=3%

Important Note: The current version of this calculator will declare that one treatment is a better fit for you even if the difference in risk between the two treatments is very small. Remember that there is some degree of error in any estimate of risk. Thus, if the estimates are very similar, you may need to discuss with your physician or health care team whether these differences are meaningful to you.

Disclaimer: Choosing between transcatheter aortic valve replacement and surgical aortic valve replacement is complex. The results of this calculator are estimates of risk only and should not be used as a substitute for medical advice. This tool is designed to help you and your doctor discuss which treatment is best for you given your medical history. All treatment decisions must be made between you and your doctor.

Starting with the Basics
Laboratory Values
Echocardiogram Values

The following are likely to be found on your last echocardiogram report. If you have had multiple echocardiograms, use the most recent results.

Cardiac Catheterization Values

The following are likely to be found on your last cardiac catheterization. If you have had multiple cardiac catheterizations, use the most recent results.

The following fields are likely to apply only to patients in the intensive care unit:
