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.
Health Quality Ontario Reviews Transcatheter Aortic Valve Implantation
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.
The Ministry of Health and Long-Term Care has accepted this recommendation.
The Ministry of Health and Long-Term Care has provided the following response: The Ministry is currently supporting transcatheter aortic valve implantation in selected high volume centres for the patient groups recommended by Health Quality Ontario
