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.

Health Technology Assessment at Health Quality Ontario

As part of our core function to promote health care supported by the best available evidence, we use established scientific methods to analyze the evidence for a wide range of health interventions, including diagnostic tests, medical devices, interventional and surgical procedures, health care programs and models of care. These analyses are informed by input from a range of individuals, including patients and clinical experts. The Ontario Health Technology Advisory Committee — a committee of the Health Quality Ontario board of directors — reviews the evidence and makes recommendations about whether health care interventions should be publicly funded or not. Draft recommendations are posted on the Health Quality Ontario website for feedback. Final recommendations are approved by our board of directors and then shared with the Ministry of Health and Long-Term Care. For more detailed information, visit our Evidence to Improve Care pages.
