Congenital heart diseases (CHD) are suggested to be associated with advanced maternal age in different ethnicities and geographical locations. To provide a profound ground for comparison with Saudi Arabian population, in this study, we have assessed the association between maternal age and congenital heart diseases for different age groups during the period from 2016 to 2018 in King Abdul-Aziz Medical City in Jeddah. In this case-control study, we found no evidence relating maternal age to the incidence of CHD. However, an association between maternal age and the type of CHD was found. Mothers who are 35 years old or younger are more likely to have a baby with atrial septal defects, while babies of mothers who are older than 35 presented mostly with ventricular septal defects and patent ductus arteriosus. Therefore, no modification to the local clinical practice, including a referral of patients for fetal echocardiography based on maternal age, is recommended.
