Do I have congenital heart disease?

On Friday, I went to the doctor's for my physical. My doctor saw that my arms are longer than normal. I am 5'3". When I am standing straight, my arms end at about 3 inches above my kneecap. My doctor said that my breathing sounds normal, but he thinks that there is a connection between congenital heart disease and my long arms. The long arms do not run in my family by the way. I am 14. Has anyone heard of this connection before?
