My main research focus is to improve understanding of fetal cardiovascular pathophysiology and the life-long consequences of the in-utero environment on the cardiovascular system; and to improve understanding of cardiovascular physiology of the pregnant woman’s heart, both during and after normal pregnancy and after complicated pregnancy. This includes studies using dedicated cardiovascular magnetic resonance (CMR) to assess fetuses with fetal growth restriction, with fetal cardiovascular malformations, and pregnant women. We have already changed clinical routine and improved prenatal diagnosis of cardiovascular malformations and continue to further investigate fetal pathophysiology anxd biomarkers to determine fetal cardiovascular alterations that cannot be visualised using standard imaging. For pregnant women, cardiac pumping physiology is incompletely understood. Nevertheless, this understanding is crucial to understand complicated pregnancies affecting the maternal cardiovascular system, to find biomarkers, and ultimately improve outcome in complicated pregnancies. We therefore apply validated methods of cardiac pumping that have never before been used in studies of the pregnant woman’s heart.
