Prelabour myocardial deformation and cardiac output in fetuses that develop intrapartum compromise at term: a prospective observational study.

Redistribution of cardiac output is responsible for the "brain sparing" effect seen during periods of acute or chronic fetal stress. We investigated the relationship between prelabour cardiac function in fetuses that subsequently developed intrapartum fetal compromise (IFC). A blinded, prospective, observational, cohort study, at Mater Mother's Hospital, Brisbane, Australia.

Obstetric and perinatal outcomes in pregnancies with isolated foetal congenital heart abnormalities.

To determine obstetric, intrapartum, and perinatal outcomes for pregnancies with isolated foetal congenital heart defects (CHDs). This was a retrospective cohort study of women that delivered an infant with an isolated major CHD between January 2010 and April 2017 at a major Australian perinatal centre. The study cohort was compared with a cohort of women with infants without CHD.

Assessment of left ventricular function using the Myocardial Performance Index in term fetuses that develop intrapartum compromise.

Objective: To investigate the relationship between the prelabour left ventricular Myocardial Performance Index (LVMPI) and intrapartum fetal compromise (IFC) in low-risk term pregnancies.

Methods: A blinded, prospective observational cohort study at the Mater Mother's Hospital, Brisbane, Australia. A cohort of 284 women with uncomplicated singleton pregnancies underwent fortnightly ultrasound from 36 weeks until delivery.
