Graphical abstract
Figure 1
Figure 1
(A) Fetal two-dimensional echocardiographic image on initial study at 31-1/7 weeks’ gestation in the four-chamber view, in systole, demonstrating a large echogenic mass (asterisk) in the anterior left atrium associated with the septum near the crux measuring 8.1 × 4.3 mm. (B) Postnatal two-dimensional transthoracic echocardiogram image on the first day of life in the apical four-chamber view, in systole, demonstrating location of the echogenic mass (asterisk) postnatally at the atrioventricular junction along the atrial septum, measuring 7.4 × 9.3 mm. Asterisk indicates P-MAIVF. LA, Left atrium; LV, left ventricle; RA, right atrium; RV, right ventricle.
Figure 2
Figure 2
(A) Two-dimensional parasternal long-axis view, in systole, on postnatal transthoracic echocardiography on the first day of life showing the P-MAIVF (asterisk) originating between the aortic and mitral valves (B), with color Doppler showing flow into the P-MAIVF in systole in the parasternal long axis view. Asterisk indicates P-MAIVF. LA, Left atrium; LV, left ventricle; RV, right ventricle.
Figure 3
Figure 3
Fetal two-dimensional echocardiography with color Doppler in the four-chamber view demonstrating blood flow into the mass during systole (arrow) on initial study at 31 weeks’ gestation (A) and follow-up study at 37 weeks’ gestation, with blood flow into the mass during systole (B). Blood flow into the mass was not initially noted on these studies, making this finding more consistent with a diagnosis of P-MAIVF. LV, Left ventricle; RV, right ventricle.
