Fetal color tissue Doppler imaging (cTDI): Assessment of fetal arrhythmias

Purpose: Assessment of fetal arrythmias of different origin by cTDI off-line analysis Material and methods: Preliminary multicenter prospective cross-sectional study. An AplioXG (Toshiba Medical Systems Corporation, Otawa, Tochigi, Japan) equipped with 1 – 5 MHz transducer was used in all centers. To achieve high frame rates the size of the scan area and the overlying color box in a longitudinal or transverse four chamber view were kept small. Cardiac cycles were digitally stored for later offline analysis. We analysed cTDI-files of 20 fetuses (range, 19+2 – 36+2 weeks) with different types of arrhythmias (SVES,…
