178 Perioperative myocardial performance in infants with down syndrome undergoing congenital heart disease repair: a comparison with infants with a normal chromosome complement

Infants with Down Syndrome (DS) undergoing surgical correction of congenital heart disease (CHD) may exhibit altered loading conditions and myocardial performance during the peri-operative period when compared with counterparts with a normal chromosome complement. This my result in higher morbidity. We aimed to characterise the impact of DS on myocardial performance and loading conditions in infants with CHD over the perioperative...
