That's the anatomy in a nutshell.... a very short and concise nutshell. I won't get into all the implications of leaky valves, and the 'electrical system' this time. Don't want your eyes to start glazing over! Too much information can lead to confusion...I speak from experience! It takes a bit to fully understand it!
Ready for a quiz now?!?

pumps blood from the body into the lungs. The left side
pumps the blood from the lungs out to the body. Each
side has an atrium and a ventricle. The atrium acts like a
“waiting room” for the blood. The ventricle does the hard
work of pushing the blood out to the lungs or body. At
the entrance and exit from each ventricle is a valve, which
acts like a door. These valves allow the ventricle to fill
with blood from one side, and then push it out the other.
Each ventricle and valve is designed to do its specific job.
The right ventricle is designed to give the blood a gentle
push to send it to the lungs. It is bigger than the left ventricle
and does not have as much muscle. The left ventricle
is designed to give the blood a strong push out to the
body. It has less space inside because its thick walls take
up more space. The valve between the left atrium and
ventricle, the mitral valve, is the body’s strongest valve.
It is designed to stay shut against the strong push of the
blood out to the body.

- One to three of every 100 Canadian children are born with one or more types of CHD's.
- More than 50% of all children born with congenital heart defect will require at least one invasive surgery in their lifetime.
- There are more than 40 different types of congenital heart defects. Little is known about the cause of most of them. There is no known prevention or cure for any of them.
- In the United States, twice as many children die from congenital heart defects each year than from all forms of childhood cancer combined.
