A congenital heart defect that results in the narrowing of the exit vessel from the heart. Depending on the severity of the narrowing, this condition can prove fatal as it prevents oxygenated blood from progressing out to the body. This condition, when combined with a PDA can allow for survival. In most cases surgery is the only possible solution, and rates of success have yet to be determined.+ Associated link: http://www.nlm.nih.gov/medlineplus/ency/article/000191.htm
