Women with congenital heart disease (CHD) are more often born preterm or small-for-gestational age and with a caesarean section. This pattern together with an increased risk of congenital anomalies seems to be repeated in the next generation.
Information on the effect of paternal CHD on their offspring is sparse. In this study we investigated if men with CHD differ from those who do not have CHD with respect to characteristics related to their own births, their reproductive patterns and the neonatal outcomes of their children.
Methods:
In this national cohort study data were derived from Swedish population-based registries.
The population consists of all men born in 1973-1983 who were alive and living in Sweden at 13 years of age (n = 522 216). The index group is men with CHD (n = 2689).
Men diagnosed with CHD were compared with men without CHD. The CHD were also divided into two groups, complex and simple CHD and comparisons between the groups were made.
Results:
Men with CHD are more likely to have been born preterm (p
They are also more likely to have been the result of a twin pregnancy (p
The neonatal outcomes of children of men with CHD do not differ from the outcomes of children of non-CHD men.
Conclusions:
Men with CHD were more often born with non-optimal characteristics compared to men without the condition. However, the increased risk does not repeat itself in the next generation.
This knowledge can lead to improved preconception counselling for couples in which the father has a CHD.
