This study evaluates the use of MTD in the assessment of cardiac diastolic function in fetuses with intrauterine growth restriction (IUGR) with placental insufficiency and in appropriate\u2010for\u2010gestational age (AGA) fetuses with hypertensive mothers.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>This study included 14 IUGR fetuses with placental insufficiency (Group 1), 13 AGA fetuses with hypertensive mothers (Group 2), and 29 AGA fetuses with healthy mothers (Group 3). Patients with other diseases were excluded. All fetuses had a gestational age of at least 25 weeks. MTD assessment was performed with the sample volume placed at the basal segment of the left ventricular side wall (LV), the interventricular septum (IVS) and the right ventricular free wall (RV). E\u2032\/A\u2032 ratios were calculated for each location. Mitral and tricuspid flows were assessed by conventional spectral pulsed Doppler.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Significant differences were found between groups for E\u2032\/A\u2032 at the IVS (<jats:italic>P<\/jats:italic> &lt; 0.001) and LV (<jats:italic>P<\/jats:italic> = 0.009), with a higher mean (\u00b1 SD) value in Group 1 (IVS: 0.92 \u00b1 0.28; LV: 0.85 \u00b1 0.19) than in Groups 2 (IVS: 0.62 \u00b1 0.09; LV: 0.68 \u00b1 0.14) and 3 (IVS: 0.71 \u00b1 0.14; LV: 0.69 \u00b1 0.15). In the RV, there was no statistically significant difference in the E\u2032\/A\u2032 ratio (<jats:italic>P<\/jats:italic> = 0.2). No differences were observed for mitral and tricuspid flow velocities and ratios.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Using MTD, the ratios between early and late diastolic myocardial velocities are higher in IUGR fetuses than in AGA fetuses at the IVS and the LV, regardless of the presence of maternal hypertension. MTD may be more sensitive than atrioventricular spectral Doppler for the detection of ventricular diastolic dysfunction in IUGR fetuses. Copyright \u00a9 2009 ISUOG.
