Aim: To assess the effect of short‐term pressure overload on left atrial (LA) mechanical function in pre‐eclampsia. Methods: Twenty women with pre‐eclampsia and 17 age‐matched healthy pregnant women were included. LA volumes were measured echocardiographically at the time of mitral valve opening (V max ), onset of atrial systole (p‐wave at the electrocardiography = V p ) and mitral valve closure (V min ) according to the biplane area‐length method. Results: The mean age, gestational age, weight and body surface area were similar in pre‐eclampsia and controls. The ventricular septal and posterior wall thickness were greater in pre‐eclampsia ( P < 0.001). There were no significant differences in LA diameter, V max , V min , V p , LA‐passive emptying volume, LA‐passive emptying fraction, LA‐active emptying volume, LA‐active emptying fraction, conduit volume, LA‐total emptying volume and LA‐total emptying fraction between the groups. Conclusion: Left atrial mechanical function didn’t change in pre‐eclampsia. We conclude that short‐lasting pressure overload is not capable of inducing changes in LA function.
