Coarctation of the Aorta is a birth defect in which part of the aorta – the tube that carries oxygen-rich blood to the body – is narrower than usual. If the narrowing is severe enough and if it is not diagnosed, the baby may have serious problems and may need surgery or other procedures soon after birth. About 4 in every 10,000 babies born has coarctation of the aorta.
The condition has been repairable since 1944. Surgical treatment involves resection of the stenosed segment of the aorta and re-anastomosis.
