ABSTRACT
OBJECTIVE: To assess the impact of prenatal diagnosis of transposition of the great arteries (TGA) on postnatal outcome. METHODS: Hundred and fifty-four patients with either simple (n = 101) or complex forms (n = 53) of TGA, diagnosed prenatally (G1, n = 88) or postnatally (G2, n = 66), who were admitted and underwent surgical correction in our centre between 1998 and 2014, were analysed. RESULTS: Prostaglandin E1 (PgE1) infusion and balloon atrial septostomy (BAS) were performed in the first 48 h after birth more commonly in G1. The hospital mortality rate for the whole group was 7.1%, higher for complex forms (13.2%) than for simple TGA (3.9%), (p = 0.034). The overall mortality rate was similar in G1 and G2. The mortality for simple TGA was higher when PgE1 infusion and BAS were implemented after the first 48 h (p = 0.001). All deaths in G2 occurred in patients first receiving PgE1 and BAS beyond 48 h. PgE1 was initiated in the first 48 h in most patients (83%) with simple TGA postnatally diagnosed. CONCLUSIONS: Adequate measures in the first 48 h after birth are essential to reduce the early mortality in TGA, especially in the simple form. This can be provided by prenatal diagnosis or by early neonatal clinical suspicion and prompt measures.
