Maternal consumption of polyphenol-rich foods in late pregnancy and fetal ductus arteriosus flow dynamics

Result: In the exposed fetuses, ductal velocities were higher (systolic: 0.96±0.23m/s; diastolic: 0.17±0.05m/s) and right-to-left ventricular ratio was higher (1.23±0.23) than in unexposed fetuses (systolic: 0.61±0.18m/s, P<0.001; diastolic: 0.11±0.04m/s, P ¼0.011; right-toleft ventricular ratio: 0.94±0.14, P<0.001). Conclusion: As maternal polyphenol-rich foods intake in late gestation may trigger alterations in fetal ductal dynamics, changes in perinatal dietary orientation are warranted.
