Regional differences in MPI in the normal fetal heart – a Tissue Doppler echocardiography (TDI) study

Objective: An explorative study on regional differences in MPI in the normal fetal heart in the second trimester of pregnancy. Materials and methods: In 20 fetuses without abnormalities in the second trimester screening between 19th and 24th week of gestation longitudinal four chamber view colour TDI cineloops of 3 cardiac cycles were recorded. Sample areas were in the subvalvulare plane, the middle segment and the apex of the myocardium of free walls of both ventricles and the interventriculare septum. Thus allowing the simultaneous measurement of myocardial velocities in different regions in the same heart cyc…
