Doctor said my son has a heart defect but i don't know what it is can you help me the doctor said that there are 3 chambers in each of the 4 chambers of your heart and that in one of my sons chambers there are only 2. and it was nothing to worry about no

The : The heart has four chambers that are separated from each other by one-way valves. These valves consist of thin, cup-shaped membranes called cusps. The cusps are attached to the heart wall along their lower edge and one side, with the free edges coming together or separating to keep the blood flowing in one direction. My guess is that your son has a condition called bicuspid aortic valve. The aortic valve, which controls blood flow out of the left ventricle (which pumps blood out of the heart and to the rest of the body), normally has three cusps. In many people, however, it only has two. This can lead to valve dysfunction over time--either failure to open all the way or failure to close all the way. If so, it needs to be fixed. At present, fixing the aortic valve requires open-heart surgery. However, there is active research into developing a valve replacement that can be inserted using a catheter introduced through a small puncture in the groin. By the time your son needs treatment, this will probably be the norm.
