A comparison of the fetal Doppler indices and cardiac function measurements of maternal asthma and control groups is shown in Table 2. Doppler indices did not differ between groups. The Tricuspid E wave velocity and tricuspid E/A ratio measured by pulse wave were statistically different between groups. (p=0.001) and (p=0.005), respectively. These parameters were lower in the case group. Left ventricular IVRT was statistically different between groups (p=0.025) and was longer in the asthma group, 45.06±8.47 ms (mean±SD), than in the control group, 40.98±7.76 ms (mean±SD). When the M-mode technique was used, the mean values of the TAPSE (p=0.010) and MAPSE (p=0.012) measurements were statistically different between the groups. The mean value of TAPSE was 8.17±1.32 mm and the mean value of MAPSE was 6.97±1.39 mm in the case group, and these values were significantly lower in the asthma group than in the control group.
