Speckle tracking echocardiography revealed lower ventricular strain values in fetuses with afterload-increasing congenital heart disease compared to controls despite normal fractional shortening (P<.01).
Case-Control
Does two-dimensional speckle tracking echocardiography detect abnormal myocardial deformation in fetuses with congenital heart disease causing ventricular afterload increase compared to gestational age-matched controls?
Speckle tracking echocardiography is feasible and potentially more sensitive than conventional fractional shortening for evaluating early cardiac dysfunction in fetuses with congenital heart disease causing increased ventricular afterload.
p-value: p=< .01
AIMS: To study myocardial deformation in fetuses with ventricular afterload increase compared with gestational age-matched controls using speckle tracking echocardiography. METHODS AND RESULTS: < .01). CONCLUSION: The results of this study showed that the ventricular LS, LSr, SRs, SRe, SRa values were lower in fetuses with LV or RV afterload increasing CHD estimated by speckle tracking imaging but LV and RV FS were normal,which indicated the strain imaging is feasible in evaluating cardiac function of fetus, and may be more sensitive.
Li et al. (Mon,) conducted a case-control in Congenital heart disease with ventricular afterload increase in fetuses. Speckle tracking echocardiography vs. Gestational age-matched controls was evaluated on Myocardial deformation (ventricular LS, LSr, SRs, SRe, SRa) (p=< .01). Speckle tracking echocardiography revealed lower ventricular strain values in fetuses with afterload-increasing congenital heart disease compared to controls despite normal fractional shortening (P<.01).
