Two patients have maintained the grafts for nearly a year, whereas adult skin would have sloughed off in less than a month...
...things can be wrong with the heart to require surgery. Some defects may be present in a child's heart or great vessels at birth (estimated annual U.S. incidence: 30,000 to 80,000 births). The great vessels (pulmonary artery and aorta) may be transposed, not harmful during fetal life but usually fatal soon after birth. Often there is a hole in the wall (septum) between the auricles or between the ventricles; there may be a hole permitting all four heart chambers to communicate. The aorta may override (straddle) both right and left ventricles. The neck (infundibulum...
