A vertical skin incision with median sternotomy for open heart surgery usually leaves an unsightly hypertrophic scar, and it makes cosmetic and psychic problems especially in young female patients. Since November 1986, we have used a bilateral submammary skin incision with dissection of a fasciocutaneous flap in 5 young female patients with uncomplicated acyanotic congenital heart disease. The exposure of the operative field was excellent. And we had good results without any significant complication associated with this type of incision.
