The main thing the heart does is pump blood.
And it's a pump that's got to pump 24 hours a day, 7 days a week.
Sometimes it has got to pump a lot of blood, (like when you're running). And then sometimes it's got to pump not too much blood (like when you're fast asleep). .
The heart pumps blood by squeezing blood in its two main pumping chambers, the right and left ventricles. The right ventricle pumps blood to the lungs, where the blood picks up lots of oxygen. And the left ventricle pumps blood to the rest of the body (including the heart itself), where that oxygen is used up. .
A PDA stands for "patent ductus arteriosus-. A PDA is an abnormal opening between the aorta and the pulmonary artery. This opening causes too much blood flow to the lungs, and gets the lungs all wet. Kids with a PDA can get winded pretty quickly, and babies with a large PDA may not grow normally.
An ASD stands for "atrial septal defect-. This is a hole in the heart, located between the left and right atriums. .
This type of "hole in the heart- can be readily closed by a special device that is placed to plug up the hole. Or a congenital heart surgeon can operate and close the hole directly.
A VSD stands for "ventricular septale defect-. This is a hole in the heart between the left and right ventricles. .
Some VSDs can be closed by plugging up the hole with a special device without an operation. However, most VSDs that need closing still need to be closed directly by a congenital heart surgeon. .
In transposition, the two great vessels are backwards in position. Soooo, the aorta is where the pulmonary artery should be, and the pulmonary artery is where the aorta should be. .
Transposition is repaired by "switching- the position of the two great vessels, so everything is where is should have been in the first place. .

Arrhythmias, or disorders of the regular rhythmic beating of the heart, are common.
