The association of scoliosis and congenital heart defects
LN Reckles, HA Peterson, WH Weidman and AJ Bianco
The effects of cardiac surgery on patients with congenital heart defects
and the subsequent development of scoliosis were studied. A group of 998
patients with congenital heart defects who were less than sixteen years old
were operated on at the Mayo Clinic during the ten-year period 1950 through
1959. Standing roentgenograms of the spine were made of 377 of the patients
ten years or more after surgery. The ages of the patients at follow-up
ranged from ten years and seven months to thirty-five years and three
months, with a mean age of twenty-one years and four months. The average
length of follow-up was fourteen years and eleven months. Of the 377
patients, thirty-two (8.5 per cent) had curves greater than 20 degrees. The
female:male ratio of patients with congenital heart defects was 1:1,
whereas of those who developed scoliosis it was 5:3. There was no
correlation between scoliosis and the following: patient's sex, cardiac
abnormality, size or side of the heart, side of the aortic arch, presence
of cyanosis, age at surgery, number and type of surgical incisions, number
and side of ribs removed, or number and type of surgical procedures.
