“…In line with other researchers we believe that it would be of great clinical interest to apply tissue Doppler (TD) echocardiography in fetal diagnostics [1,2] . Several studies have reported the feasibility of TD for assessing fetal cardiac function using both spectral TD [3][4][5] and color-coded tissue velocity imaging (TVI) [2,[6][7][8] .…”

“…Previous studies have reported observed limitations regarding the occurrence of fetal and/or maternal movement [2,[23][24][25][26][27] and the importance of exact placement of the ROI for offline analysis [26,27] . As far as reproducibility is concerned this creates difficulties when considering the environmental changes between the exams and in placing the ROI in the exact same location between investigations.…”

“…Several studies have reported the feasibility of TD for assessing fetal cardiac function using both spectral TD [3][4][5] and color-coded tissue velocity imaging (TVI) [2,[6][7][8] . The advantage of these methods over conventional echocardiography is their ability to quantify cardiac function by providing detailed regional information about myocardial velocity, displacement and strain pattern [9] -information that in several studies have indicated prenatal pathology [5,6,8,[10][11][12][13][14] .…”

Objective: The introduction of color-coded tissue velocity imaging (TVI) in fetal medicine is quite recent, and as this method is presently evaluated and developed in regard to diagnostic precision it is of outmost importance to evaluate the reproducibility for adequate clinical use. In this study, reproducibility and intra-and inter-observer variability was assessed for offline analysis as well as echocardiography investigations. Also, we evaluated the importance of exact placement of the region of interest (ROI).Methods: TVI recordings from 21 fetuses, at a gestational age of 27 to 41 weeks, were acquired at 208-239 frames/s for subsequent offline analysis. All recordings were performed with the transducer positioned to provide an apical four-chamber view and the myocardial velocity data was obtained from basal inferoseptum. The data set was analyzed according to Bland-Altman and reproducibility was expressed as the standard error of a single determination, estimated from duplicate determinations in percentage of the total. Results:The variation of reproducibility for the echocardiography investigation ranged from 2.0% to 9.8%. The duration of left ventricular ejection, and the peak velocities of early diastolic filling and atrial contraction being the most robust events measured. The variation of inter-observer variability for the echocardiography investigation ranged from 1.5% to 8.4%, and the variation of intra-and inter-observer variability for the offline analysis ranged from 1.2% to 10.4%. Least robust were the events of shortest duration, including isovolumetric contraction and relaxation. Conclusion:We believe that TVI measurements of the fetal myocardium could be performed in the clinical routine with acceptable reproducibility.

“…Other color tissue Doppler studies reported about increasing annular velocities during gestation in normal fetuses placing the ROI in the RV free wall or annulus 14,15 . We think, that measurements of tissue velocities are highly dependent on region of interest placement (even close to the atrioventricular level), the basically undefined ROI size (in the literature this ranges between 1 and 3mm) and the different ultrasound machines with post-processing algorithms [14][15][16][17][18][19][20] . Therefore, published tissue velocities vary and cannot be used interchangeably.…”

Introduction: The long-term outcome of patients with HLHS (hypoplastic left heart syndrome) is mainly determined by right ventricular function. Our study examines, whether there are differences in segmental right ventricular myocardial displacement and tissue velocities of fetuses with HLHS compared to healthy fetuses during gestation.Materials and methods: A prospective study was conducted including 20 fetuses with HLHS and 20 gestational age matched controls. c-TDI (colour tissue Doppler imaging) derived systolic and diastolic velocities as well as myocardial displacement were assessed in three different locations of the right ventricle (RV). A ROI (region of interest) was placed in the basal, middle and apical part of the myocardium. Possible changes of c-TDI indices in the course of pregnancy and between the three different segments were investigated in both groups.Results: HLHS fetuses showed significantly lower e' velocities measured in the basal and middle part of the RV compared to healthy controls (p < 0.05). Basal displacement showed significantly lower values in HLHS fetuses compared to controls. In control fetuses but not in HLHS fetuses there was a significant increase of basal diastolic velocities and displacement in the course of pregnancy. According to myocardial velocities and displacement values there was a significant decrease from the base of the fetal heart to the apex pointed in both groups.Conclusions: An altered right ventricular myocardial function in HLHS fetuses within different myocardial segments could be demonstrated. An apicobasal gradient with higher velocity and displacement values in the basal part of RV myocardium could be found in both groups. The technique may be of value in the prenatal assessment of myocardial function, however its role as a monitoring tool and outcome predictor needs to be defined.
