21. 3D versus 2D echocardiography assessment of maternal cardiac remodeling in gestational hypertension

Introduction Considering that the left ventricle (LV) is losing its standard elliptical shape during pregnancy and that these changes are more pronounced if pregnancy is complicated by hypertension, we assumed that there was a difference in geometric remodeling of the LV evaluated by 2D compared to 3D echocardiography in gestational hypertension (GH). Objective To establish the difference between 2D and 3D evaluation of maternal cardiac remodeling in GH and reversibility of these changes after delivery. Methods 55 women with GH and 26 normotensive pregnant women as controls underwent a complete echocardiography in the third trimester and 6 weeks after delivery, to assess parameters of chamber quantification, wall thickness and LV myocardial mass index. The LV remodeling was determined as normal geometry (NG), concentric hypertrophy (CH), eccentric hypertrophy (EH) and concentric remodeling (CR) according to the reference values of Relative wall thickness and LVmass index due to recommendations of Europian Association of Cardiovascular Imaging and American Society of Echocardiography. Results Hypertensive women had statistically significant higher values of almost parameters of the LV geometry, that caused most abnormal geometry in women with GH (p  i evaluated by 3D and 2D, there was also the difference in geometric remodeling but only in GH group. Thus, evaluated by 3D, NG was presented in GH in 25% vs 26,8% meassured by 2D (p  Conclusion There was statistically significant diference between 3D and 2D estimation of the maternal cardiac remodeling in gestational hypertension.
