Aortic valve stenosis is a common heart disease when the aortic valve in the heart has narrowed, causing the heart to work harder to pump blood to the body.

The usual treatment is to replace the damaged valve with an artificial one through open-heart surgery -- known as surgical aortic valve replacement. Another option, called transcatheter aortic valve implantation, is a less invasive procedure that may benefit people who are too frail for open heart surgery. This procedure involves going through an artery, most commonly in the leg, to place an artificial valve inside the damaged one.

Health Quality Ontario looked at how safe and effective transcatheter aortic valve implantation is for people with severe aortic valve stenosis who are at intermediate risk for surgery (which means at increased risk of dying within 30 days of a surgical valve replacement). We also looked at the cost-effectiveness and budget impact of publicly funding this procedure for people at this risk level, and we talked with people with aortic stenosis to learn about their experiences, preferences and values.

About Health Quality Ontario

Health Quality Ontario is the provincial lead on the quality of health care. We help nurses, doctors and other health care professionals working hard on the frontlines be more effective in what they do—by providing objective advice and data, and by supporting them and government in improving health care for the people of Ontario.

We focus on making health care more effective, efficient and affordable through a legislative mandate of:

  • Reporting to the public, organizations, government and health care providers on how the health system is performing,

  • Finding the best evidence of what works, and

  • Translating this evidence into clinical standards; recommendations to health care professionals and funders; and tools that health care providers can easily put into practice to make improvements.
