Objective To compare the ability of two different methods for longitudinal annular motion measurement, M‐mode and tissue Doppler imaging ( TDI ), to demonstrate cardiac dysfunction in intrauterine‐growth‐restricted ( IUGR ) fetuses. Methods Cardiac longitudinal annular motion in the basal free wall of the left ventricle (mitral annulus), interventricular septum and tricuspid annulus was assessed in 23 early‐onset IUGR cases and 43 controls by TDI (annular peak velocities) and M‐mode (displacement). Results All annular parameters were significantly decreased in the IUGR group with respect to controls using both methods. M‐mode showed a trend towards equal performance as classifier between cases and controls, as compared to TDI , mainly in the tricuspid annulus. Conclusions Both M‐mode and TDI demonstrate annular motion changes and consequently cardiac dysfunction in IUGR fetuses. M‐mode imaging is simpler to perform and could be as sensitive as TDI for detecting subtle changes. Copyright © 2012 ISUOG. Published by John Wiley & Sons Ltd.
