Abstract
OBJECTIVES: Fetal cardiac function can be quantified by different methods. This is the first approach of real three-dimensional(3 D)-based speckle tracking echocardiography in the fetus to assess different cardiac strain parameters. METHODS: We present preliminary results of fetal global myocardial strain analyses. For fetal echocardiography a Toshiba Artida system was used. Based on an apical or basal four-chamber view of the fetal heart, raw data volumes with a high temporal resolution were acquired and digitally stored. RESULTS: 8 individual healthy fetuses with an echocardiogram performed between 21 and 37 weeks of gestation were included. The mean temporal resolution was 31.2 ± 4.3 volumes per second (vps). Basic parameters such as longitudinal and circumferential strain as well as advanced 3 D myocardial motion patterns such as area strain, rotation, twist and torsion were assessed. CONCLUSION: Currently the assessment of fetal myocardial deformation parameters by 3 D speckle tracking seems to be technically feasible only in individual cases. In the future further development of this technique is necessary to improve its application in fetal echocardiography. © Georg Thieme Verlag KG Stuttgart · New York.
