Objective: To evaluate ventricular contractility and profile heart deformations in fetuses of hyperglycemic mothers using the Speckle tracking imaging (STI). The fractional area change (FAC), global longitudinal strain (GLS) and global sphericity index (GSI) of the 4-chamber view (4-CV) were computed.
Study Design: Dynamic 4-CV images of 60 fetuses exposed to maternal diabetes (MD) and 60 controls were retrospectively collected between 19 and 37 weeks of gestation.
Classical absent pulmonary valve syndrome (APVS) with tetralogy of fallot (TOF) is a rare congenital cardiac anomaly commonly associated with the absence of patent ductus arteriosus (PDA), which is mostly diagnosed after 20 weeks of gestation by fetal echocardiography. This case of APVS with TOF was suspected at 13 weeks of gestation and diagnosed at 14 weeks of gestation with an obvious PDA. The pulmonary arterial trunk and the branches did not dilate obviously.
