Preeclampsia (PE) is a major cause of maternal and perinatal morbidity and mortality and is thought to be predominantly as the consequence of impaired placentation. A major challenge in modern obstetrics is early identification of pregnancies at high-risk of early onset PE and undertaking the necessary measures to improve placentation and reduce the prevalence of the disease.
