Background Preeclamsia (PE) is a multisystem disorder that affects maternal and fetal outcomes. We aimed to assess right heart function in PE by echocardiography using conventional, tissue Doppler techniques, and 2D and 4D strain. Patients and methods This study comprised 100 pregnant women aged between 32 and 41 weeks divided into two groups: group 1 included 50 pregnant women with PE, who were compared with 50 age-matched normotensive pregnant women as a control group (group 2). They were subjected to proteinuria detection, pelviabdominal ultrasound, conventional echo, tissue Doppler imaging, and 2D and 4D speckle tracking echocardiography for measurement of right ventricular (RV) dimensions and RV systolic and diastolic function indices. Results The higher percentages of cesarean delivery, low birth weight, and need for NICU were present in group 1 compared with group 2. There were significantly increased RV dimensions in group 1 compared with group 2. TAPSE (2D and 4D), RV FAC (2D and 4D), average RV Sa, 4D-RV EF, 2D-RV strain, 4D septal strain, and 4D-RV free wall strain were significantly lower in group 1. RV MPI (PW and TDI) was higher in group 1 patients. Both tricuspid E/A and RV E/Ea were significantly higher in group 1. There was a positive correlation between proteinuria and mean arterial pressure, 2D-TAPSE, RV PW-MPI, and RV TD-MPI, whereas there was a negative correlation with 2D and 4D-RV strain, 4D RVEF, 4D-FAC, and T E/A. Conclusion Women with PE had significant RV structural and functional changes. Assessment of RV by newer echocardiographic modalities such as speckle tracking echocardiography and 4D-echocardiography can detect subtle cardiac changes that may help in early diagnosis of maternal and fetal complications.
