Ontario Health Technology Advisory Committee Recommendations
- The Ontario Health Technology Advisory Committee recommends that transcatheter aortic valve implantation be publicly funded in patients with severe symptomatic degenerative aortic valve stenosis:
- Who are not candidates for surgical aortic valve replacement or
- Who have an estimated risk of mortality of 8% or greater within 30 days of surgery, as determined by a multidisciplinary cardiac team after evaluating the patient’s Society of Thoracic Surgeons risk assessment score and other patient characteristics.
- The Ontario Health Technology Advisory Committee recommends that transcatheter aortic valve implantation be offered only in selected hospitals, as determined by the Cardiac Care Network of Ontario.
- The Ontario Health Technology Advisory Committee recommends that transcatheter aortic valve implantation be publicly funded in patients with severe symptomatic degenerative aortic valve stenosis:
- Ministry Response
-
The Ministry of Health and Long-Term Care has accepted this recommendation.

The aortic valve is one of four valves in the heart. Blood flows through the aortic valve when it is pumped from the left ventricle of the heart into the aorta (the main artery in the body). Aortic valve stenosis occurs if the valve narrows and cannot open all the way, partially blocking the flow of blood out of the heart. Severe aortic valve stenosis is a life-threatening condition that can lead to death, usually from heart failure.
The diseased aortic valve can be removed and replaced with an artificial valve, but doing this involves open-heart surgery. Transcatheter aortic valve implantation, or TAVI, is a newer procedure. In most cases, cardiologists make a small opening in an artery near the groin to insert a catheter to deliver and implant the new valve. We reviewed the evidence that compared TAVI with surgical aortic valve replacement.
