ORLANDO — Listing unborn babies with severe prenatal heart problems results in earlier heart transplants and comparable outcomes when compared with babies added to a transplant list after birth, researchers reported here.
A prospective, multicenter, events-driven data registry was used to determine outcomes of babies listed for heart transplantation before birth. The researchers’ search identified 4,365 children added to a heart transplant list for the study period of 1993 to 2009. Unborn babies comprised 1% and newborns (aged 0 to 30 days) comprised 19.8% of those listed.
The most common indication for fetal listing for heart transplant was congenital heart disease, with left-side obstructive lesions predominating.
Unborn babies were listed for an average 18 days before delivery. About half of the babies listed before birth waited 1 month to receive a transplant while newborn babies waited 3 months, on average. The median wait-list time to heart transplant after birth was 25 days for babies listed before birth vs. 39 days for newborns.
