The left ventricular outflow tract and ventricular function were difficult to assess due to the size of the mass. As a result, fetal cardiac MRI with a 1.5-T imager was performed at 31 weeks, by using accelerated imaging (compressed sensing), translational motion correction, and data-derived retrospective gating, to produce motion-compensated high-spatial-resolution cine images of the fetal heart (Figure; Movie E1 [online]). Fetal cardiac MRI was used to identify the location of the mass in the left ventricle, confirm the patency of the left ventricular outflow tract, determine the fetal right and left ejection fractions (21% and 36%, respectively), and calculate the volume of the mass (35 mL). These images highlight the complementary role of fetal cardiac MRI in understanding complex fetal cardiac anatomy and function in the setting of an intracardiac mass.Coronal balanced steady-state free precession fetal cardiac MR images depict a large rhabdomyoma (M) in the left ventricle, the right ventricular outflow tract (RVOT, A), left ventricular outflow tract (LVOT, B), a pericardial effusion (P), and liver (L). Intracranial masses were also present on MR images of the brain (not shown).Download as PowerPointOpen in Image Viewer Get the Flash Player to see this video.Movie 1 Multisection multiphase motion-compensated coronal balanced steady-state free precession (bSSFP) cine images of a fetal heart with a giant cardiac rhabdomyoma in the left ventricle.Download Original Video (6.6 MB)Disclosures of Conflicts of Interest: C.W.R. disclosed no relevant relationships.
