This condition is characterized by a constriction of the vessels and a low plasma volume with low cardiac output and stroke volume. The assessment of the maternal hemodynamic condition requires an echocardiographic evaluation or the use of other non invasive devices, but in the absence of these instruments there is also a simple clinical method that can give us an idea of the maternal hemodynamic profile of the mother: the measurement of blood pressure and heart rate. In a hypodynamic low cardiac output condition, the choice of drugs that might reduce cardiac output and myocardial contractility to lower blood pressure might be irrational, whereas pharmacological interventions that directly act on the vessels reducing vasoconstriction, such as dihydropyridine calcium channel blockers and nitric oxide donors, might be more appropriate.

The most important parameters that can be assessed by intrapartum ultrasound include the fetal head position, station and attitude. In the first section of this review, we explain how to use intrapartum ultrasound to assess these parameters, providing a broad overview of the different available techniques. The second section describes the indications of intrapartum ultrasound and provides some insight on how intrapartum ultrasound may help to improve management of abnormal labor. In the last section, we discuss the future perspectives of intrapartum ultrasound. This includes topics such as the incorporation of new labor parameters, such as maternal pelvimetry, molding and caput succedaneum; the development of “sonopartograms”, and the use of artificial intelligence.

Pregnancy can be considered as the ultimate stress test for these organ systems. Preeclampsia and gestational hypertension may be considered as a derangement of the hemodynamic and cardiovascular system during pregnancy. During later life the hemodynamic and cardiovascular system again derails when aging has its toll. Cardiovascular morbidity and mortality are greatly increased after pregnancies complicated by hypertensive disorders of pregnancy. These complications must be acknowledged by health care providers as a risk factor for later cardiovascular disease. All women after HDP should be followed scrutinous at least during the first 5–10 years after their deliveries. The focus of the follow-up should be on the development of hypertension. Women with an increased risk are those with early-onset preeclampsia, recurrent preeclampsia and preeclampsia in the last pregnancy.
