Oral communication abstracts Objectives: Transposition of the great arteries (TGA) represents a neonatal emergency. In 1999, it has been demonstrated that prenatal diagnosis improves outcome, but since then these results had not been confirmed by other centers. The aim of this study is to assess whether prenatal diagnosis of TGA has any impact on short-term outcome. Methods: We report our results over the last 14 years (1995-2008), on a series of 252 cases of TGA, including 208 cases diangnosed postnatally and 39 cases diagnosed prenatally. Cases with extra-cardiac anomalies and those with contraindications to the switch operation were excluded from the study. Variables considered included: age at admission, intubation, Rashkind septostomy, age at surgery, pre-and post-operative mortality, 1 month survival. Statistics were performed with the SPSS package. Results: Gestational age at delivery, birth weight, Apgar Score, coronary arteries anatomical pattern, time of total circulatory support and length of stay in ICU did not significantly differ between the groups.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
