Résumé : Patent ductus arteriosus (PDA) is the most common cardiac abnormality of the preterm infant. Its incidence is inversely related to gestational age, such that it affects almost 60% of infants less than 28 weeks’ gestation. Data published in 2007 demonstrated that spontaneous closure of the ductus occurs in 30% of infants with birthweights below 1500 g (very low birth weight [VLBW]) [1]. It is obvious that percentages are decreasing for each lower birthweight category (Table 80.1), but also that a markedly wide variation exists among centers. This may reflect the influence of varying factors on the closure of the ductus.
