The role of home monitoring in interstage management of infants following the Norwood procedure.

Although outcomes for infants with complex single ventricle heart defects have steadily improved in recent decades, there is still a significant risk for mortality and morbidity during the interstage period between stage 1 Norwood hospitalization discharge and stage 2 palliation. Home monitoring programs, which involve parental surveillance of daily weight and oxygen saturations during the interstage period, have been shown to significantly improve survival rates. This article describes the potential risk factors or causes of interstage mortality and reviews the role of home monitoring in early detection and potential prevention of adverse outcomes.
