Learn from the experts
What can heart valves used for replacement be made out of?
The most common heart valves used for replacement contain cow tissue (the heart sac of the cow), or from pig tissue, or possibly a combination of the two. In less common situations, a valve can be taken from a cadaver, or a valve from another section of your heart can be used and transferred, but these last two types have very specific indications. Your surgeon will review the valve options for you if you are a candidate for valve replacement surgery.
What is TAVI?
TAVI stands for Transcatheter Aortic Valve Implantation. Basically a catheter is used to access and replace the valve in your heart rather than opening your chest and gaining access that way. It is considered a less invasive approach than the traditional surgery and may be offered to you if your medical condition raises concerns about your potential risks with a surgery.
What are the symptoms of dementia?
There are subtle changes that you (or those around you) may notice which could be signs of dementia. These include short-term memory difficulties, irritability, issues finding the right word when speaking, and challenges following through on tasks. If you are noticing these symptoms in yourself, or someone close to you, you can speak with your family doctor to see if dementia could be developing.
